ACM acrylic rubber seal ring: resistance to oil, high temperature resistance, good weather resistance, but mechanical strength, compression deformation rate and water resistance are slightly poor. It is generally used in automotive drive systems and power steering systems. Not suitable for hot water, brake oil, phosphate ester. Generally, the temperature range is from -25 to 170 ° C.
NR Natural Rubber Seals: It has good wear resistance, elastic, tear strength and elongation. However, it is easy to aging in the air, and it is easy to expand and dissolve in mineral oil or gasoline, alkali-resistant but not resistant acid. Suitable for use in liquids such as hydroxide ions such as car brake oil, ethanol. Generally, the temperature range is -20 to 100 ° C.
