A Comprehensive Guide to EPDM 85 in China
EPDM (ethylene propylene diene monomer) rubber is a versatile synthetic elastomer widely used in various industries due to its excellent properties. EPDM 85, specifically, refers to a grade of EPDM with a Shore A hardness of 85. This guide will delve into the specifics of EPDM 85, focusing on its presence and applications within the Chinese market. We will explore its technical features, different types, and key manufacturers and suppliers.
Understanding EPDM 85’s Properties and Applications
EPDM 85 is known for its exceptional resistance to weathering, ozone, and UV radiation. This makes it ideal for outdoor applications. Its resistance to heat and steam, up to 150°C and even 180°C with specialized types, further expands its utility. Companies like Kaflon (Xiamen) Seal Co., Ltd. (www.kaflon-seal.com) highlight these features in their product descriptions. The material’s compatibility with various chemicals, including many acids and certain hydraulic fluids, makes it suitable for demanding industrial environments. However, it’s crucial to note its incompatibility with mineral oils and greases. This characteristic is vital for selecting the right EPDM for a specific application.
The versatility of EPDM 85 is reflected in its diverse applications. Common uses include O-rings, flat seals, funnels, grooved rings, and wipers. Its excellent properties make it a preferred choice in automotive, construction, and industrial sectors. Furthermore, the material finds use in various specialized applications, demonstrating its adaptability to different needs. The high demand for EPDM 85 in China is evident in the numerous suppliers listed on platforms such as TradeWheel (www.tradewheel.com).
