A Comprehensive Guide to Rubber Materials in China
China’s rubber industry is a significant player on the global stage, encompassing production, consumption, and manufacturing of diverse rubber materials. Companies like Chengdu Eson New Material Co.,Ltd (www.esonmaterial.com) and Yusheng Enterprise Limited (www.yushengmax.com) are prominent examples of the breadth and depth of this sector. This guide delves into the technical aspects and variety of rubber materials manufactured in China.
Understanding Rubber Material Types and Properties
Rubber materials are broadly classified into natural and synthetic rubbers. Natural rubber, derived from the latex of rubber trees, exhibits excellent elasticity and resilience. However, its performance is limited by temperature and chemical resistance. Synthetic rubbers, conversely, are engineered to possess specific properties tailored to diverse applications. These properties are achieved through the use of various polymers, fillers, and additives. Companies like Yoda Rubber (www.yodarubber.com) showcase the extensive range of rubber products based on these materials.
Technical Features of Common Rubber Materials
The following table highlights the key technical features of some widely used rubber materials in China:
| Rubber Type | Tensile Strength | Elongation | Hardness | Temperature Resistance | Chemical Resistance |
|---|---|---|---|---|---|
| Natural Rubber (NR) | High | High | Moderate | Low | Low |
| Styrene Butadiene Rubber (SBR) | Moderate | Moderate | Moderate | Moderate | Moderate |
| Nitrile Butadiene Rubber (NBR) | Moderate | Moderate | Moderate to High | Moderate | Good (oils, fuels) |
| Ethylene Propylene Diene Monomer (EPDM) | Moderate | Moderate | Moderate | Good | Excellent (ozone, weather) |
| Fluoroelastomer (FKM/Viton) | High | Moderate | High | Excellent | Excellent (chemicals, oils) |
| Silicone Rubber (VMQ) | Low to Moderate | High | Low to Moderate | Excellent (high and low temperatures) | Good (ozone, weather) |
Many Chinese manufacturers, such as Zhong Xiang Rubber Products Co., Ltd (www.zxrubberco.com), specialize in rubber products with specific performance characteristics, often incorporating advanced materials and manufacturing techniques. Beijing Rubber (beijingrubber.com) for instance, emphasizes quality control measures like online gauge control and metal screening to improve the final product.
