What is the temperature tolerance of silicone rubber products?
Silicone Rubber Material Characteristics and Applications
Silicone product could withstand -40°C to 250°C; rubber could withstand -20°C to 100°C generally. According to different materials, rubber has different temperature resistance. Some rubber could withstand higher temperature such as FKM may undergo 200°C. Silicone has better heat resistance than rubber. If it is not use in special condition such as benzene and ether solvents, it is the most suitable material for thermal insulation.
Silicone rubber with different material properties can be added with pigments or printed colored into commercial products. Through silicone injection OEM services, silicone compression molding and other manufacturing methods, it is widely used in industrial applications such as mechanical electronics and electric vehicle industries. Medical and daily necessities, etc. Through the comparison table below, you can better understand the industries that different materials are suitable for. Jhanhui is committed to providing customers with a more competitive market space, increasing production capacity and reducing costs for you, and matching the delivery date.
