Silicone hip pad wear resistance test: full analysis of international standards
In today’s global market environment, silicone hip pads have received widespread attention and popularity due to their unique comfort and functionality. For international wholesale buyers, it is crucial to ensure that the quality and performance of silicone hip pads meet international standards, especially the key indicator of wear resistance. Wear resistance not only affects the service life of the product, but is also directly related to the consumer’s experience and satisfaction. This article will explore in depth the internationally recognized standards for wear resistance testing of silicone hip pads, providing you with a strong reference for procurement and quality assessment.
1. The importance of wear resistance testing
Silicone hip pads are mainly used to improve sitting posture, reduce pressure and improve sitting comfort. They are subject to repeated friction and pressure in daily use. Wear resistance testing can simulate the wear of products during actual use and help evaluate the performance changes of products after long-term use. Through strict wear resistance testing, high-quality and long-life silicone hip pad products can be effectively screened out to ensure that consumers get a satisfactory product experience. At the same time, it also helps companies establish a good brand image in the international market and enhance the competitiveness of their products.
2. Internationally recognized test standards for the wear resistance of silicone hip pads
(I) ISO 5470-1:2016 “Rubber or plastic coated fabrics – Determination of wear resistance – Part 1: Rotating platform, oscillating and finger abrasion testers”
The ISO 5470-1:2016 standard specifies the method for determining the wear resistance of rubber or plastic coated fabrics using a Taber abrasion tester. This standard is applicable to various rubber or plastic coated fabrics, including silicone hip pads. The test principle is to fix the sample on a rotating platform, contact and rotate it with the abrasive, and evaluate the wear resistance of the sample by the mass loss after a certain time or number of revolutions. The standard provides detailed test conditions, including the selection of parameters such as abrasive type, load, and rotation speed, to ensure the accuracy and comparability of the test results. Its advantage is that it can simulate the wear conditions under different use conditions, providing a comprehensive reference for the wear resistance evaluation of silicone hip pads.
(II) ISO 12947 “Textiles – Test method for the determination of abrasion resistance of fabrics by the Martindale method”
The ISO 12947 standard series is a widely recognized abrasion resistance test standard in the field of textiles. ISO 12947-1 specifies the general test method for the determination of abrasion resistance of fabrics by the Martindale method, while ISO 12947-2, ISO 12947-3 and ISO 12947-4 respectively provide detailed provisions for different types of sample clamping and abrasive application. Although this standard is mainly for textiles, since silicone hip pads will come into contact with textiles and generate friction during use, their abrasion resistance test can also refer to this standard. The Martindale method uses a specific sample clamping device to rub the sample against the abrasive under a certain pressure, and the abrasion resistance is evaluated by the appearance change or mass loss after a certain number of times. The advantage of this method is that it can simulate the actual friction between the fabric and the silicone hip pad, which is of great significance for evaluating the abrasion resistance of the silicone hip pad when it is in contact with textiles such as clothing.
(III) ASTM D4060 “Standard Test Method for Evaluating the Wear Resistance of Materials Using Taber Abrasion Tester”
The ASTM D4060 standard is one of the classic standards developed by the American Society for Testing and Materials for evaluating the wear resistance of various materials. This standard uses the Taber Abrasion Tester to measure the wear resistance of materials by allowing the specimen to contact and rub against a rotating grinding wheel under a certain load. For silicone hip pads, the appropriate specimen preparation method can be selected according to its shape and size, and the test can be carried out according to the friction revolutions and loads specified in the standard, and then the wear resistance of the specimen can be evaluated by measuring the mass loss or appearance change of the specimen. The Taber Abrasion Tester has a variety of grinding wheel types and load options, which can be flexibly selected according to different test needs. Its test results have high repeatability and comparability, and have been widely used and recognized internationally.
(IV) GB/T 30314-2013 Rubber or plastic coated fabrics – Determination of abrasion resistance – Taber method
GB/T 30314-2013 is my country’s national standard, equivalent to ISO 5470-1:2006. This standard specifies the method of using Taber abrasion tester to determine the abrasion resistance of rubber or plastic coated fabrics, which is applicable to similar products such as silicone hip pads. Its test method and parameter settings are basically consistent with ISO 5470-1 standard, providing a unified test basis for domestic silicone hip pad manufacturers and testing agencies, and also facilitating integration with international standards, promoting international trade and exchange of products. In the domestic market, silicone hip pad products that meet GB/T 30314-2013 standard have better quality and performance assurance, and can meet consumers’ basic requirements for product wear resistance.
(V) ISO 20868:2001 “Footwear – Test methods for insoles – Abrasion resistance”
The ISO 20868:2001 standard specifies the test method for the abrasion resistance of insoles. Although it is mainly for insole products, the wear resistance test method of silicone hip pads can also be used for reference because of the similarities between silicone hip pads and insoles in terms of function and use environment. This standard uses a specific friction test device to simulate the friction and movement of the insole in the shoe. After a certain number of frictions, the wear amount or appearance change of the insole is measured to evaluate its wear resistance. Its test conditions and methods are optimized according to the characteristics of footwear products, which can more realistically reflect the wear resistance of insoles in actual use, and have certain reference significance for the wear resistance evaluation of silicone hip pads in similar friction environments.
3. Comparison and selection of wear resistance test methods
Different wear resistance test standards and methods have their own characteristics. When choosing a wear resistance test method suitable for silicone hip pads, the following factors need to be considered comprehensively:
(I) Product characteristics and usage scenarios
If the silicone hip pad is mainly used in scenes where it comes into contact with textiles, such as being placed on a seat and in contact with clothing, then referring to the ISO 12947 standard for testing can better simulate the friction conditions in its actual use and evaluate its wear resistance with textiles.
For scenes where the silicone hip pad comes into contact with other hard materials, such as certain plastic or metal parts, the Taber abrasion test method in the ASTM D4060 standard may be more applicable because it can simulate the friction and wear characteristics with different materials by selecting a suitable grinding wheel.
(II) Test purpose and accuracy requirements
If the purpose is to conduct a quick and preliminary screening of the wear resistance of the silicone hip pad, some relatively simple and fast test methods can be selected, such as the falling sand method, but it should be noted that the accuracy and repeatability of the test results are relatively low.
If the purpose is to obtain accurate and reliable wear resistance data for product quality control, R&D improvement or to align with international high-end market standards, it is recommended to select ISO 5470-1, ASTM D4060 and other internationally recognized standard methods with high test accuracy. These methods can provide detailed and accurate wear data, providing strong support for product quality assessment and improvement.
(III) Test equipment and cost factors
The equipment and costs required for different wear resistance test methods vary greatly. For example, the price of equipment such as Taber abrasion tester and Taber abrasion tester is relatively high, and there are certain requirements for the test environment and the technical level of the operator.
Some simple friction test devices or manual test methods have low equipment costs and relatively simple operations, but may be insufficient in test efficiency and result accuracy. Therefore, when choosing a test method, it is necessary to comprehensively weigh the actual equipment conditions, budget and requirements for test result accuracy of the enterprise.
4. Key points to ensure that the wear resistance of silicone hip pads meets international standards
(I) Raw material selection
High-quality silicone raw materials are the basis for ensuring the wear resistance of hip pads. When selecting silicone raw materials, attention should be paid to its mechanical properties, such as tensile strength, tear strength, etc., which are closely related to the wear resistance of the material. Choose a basic silicone material with good wear resistance, and add an appropriate amount of reinforcing agent, wear-resistant additive, etc. as needed to improve the overall wear resistance of the silicone mixture.
(II) Production process control
Strict production process control is essential to ensure the wear resistance of silicone hip pads. During the production process, the mixing uniformity of silicone should be ensured to avoid local performance differences; the vulcanization process parameters, such as temperature and time, should be accurately controlled to ensure that the cross-linking degree and mechanical properties of silicone are in the best state; at the same time, during the molding process, attention should be paid to avoid the generation of defects such as bubbles and impurities, which will seriously affect the wear resistance and service life of the product.
(III) Quality inspection and monitoring
Establish a complete quality inspection system to strictly inspect and monitor the wear resistance of silicone hip pads. During the production process, samples are regularly taken for wear resistance testing to promptly discover and solve quality problems in production; before the product leaves the factory, strict wear resistance sampling is carried out in accordance with international standards to ensure that each batch of products meets quality requirements. In addition, attention should be paid to market feedback, and wear resistance problems that occur during consumer use should be tracked and analyzed, product design and production processes should be continuously improved, and the overall quality and performance of the product should be improved.
