Polymer Characteristics
-
In addition to excellent general characteristics including heat resistance,weather resistance,ozone resistance, chemical resistance and electrical properties.
These grades of EP also offers a faster vulcanization rate,and lower compression set and stronger resistance to flex cracking than general-purpose EP.JSR EP grades are suited to application in functional parts such as packing or diaphragms.
EP331 and EP342,in particular. Offer the best compression set and cold resistance among any of SR EPgrades through the use of array operations with ethylene and propylene. Many of JSR grades have a low Mooney viscosity (M),and JSR EP lineup offers an excellent balance of both product properties and processability.

The Rubber Piston Cup user EPDM as the raw material labeled EP-35,all imported from
Japanand.all are imported to bring better sealing performance and oil return characteristics.
