A Comprehensive Guide to Silicone Rubber in China: From Manufacturing to Applications
Silicone rubber, a versatile synthetic elastomer, plays a crucial role in numerous industries globally. China, with its robust manufacturing capabilities, has become a significant player in the global silicone market. This guide explores the intricacies of silicone rubber in China, encompassing its manufacturing processes, diverse types, technical features, and widespread applications. We will delve into the reasons behind China’s success in this field, examining aspects highlighted by industry leaders like siliconesbenefits.cn, www.cfsilicones.com, www.fictiv.com, www.newtopsilicone.com, and rysilicone.com.
Understanding Silicone Rubber: Chemistry and Curing
Silicone rubber’s unique properties stem from its chemical structure. It’s composed of alternating silicon and oxygen atoms (Si-O) forming an inorganic backbone, distinct from organic polymers with carbon-carbon (C-C) backbones. This difference contributes to its exceptional heat resistance, flexibility, and chemical inertness. The most common type is polydimethylsiloxane (PDMS).
The curing process transforms liquid silicone into a solid elastomer. Several methods exist, each influencing the final product’s properties. Condensation curing uses tin catalysts and atmospheric moisture, releasing byproducts. Platinum curing, favored for medical applications, is cleaner and doesn’t produce byproducts. Peroxide curing is cost-effective, suitable for tubing and O-rings. UV curing offers rapid curing, ideal for electronics and some medical uses. www.fictiv.com details these curing processes comprehensively.
