High avulsion resistance silicone rubber
Click rate:564   Time:2022-05-10

1, Product introduction: translucent or milky white high tear resistance type fluorosilicon rubber, good physical properties and processing properties, with good tear resistance, vulcanization speed and good fluidity characteristics, more suitable for the production of complex seals, as well as diaphragm and other products.


2, use method: Mixing: first in the smelting machine to return several times, add double penta vulcanization agent (add ratio 0.6-1%), eat the material and then return to 0.5mm-1mm thin through 8-10 times after the film park. Vulcanization: The mixed rubber with a good vulcanization agent is returned to the sheet or cut into the desired shape, and then to the molding machine to press vulcanization molding (customers should determine the most appropriate vulcanization temperature and time according to the size of the product and vulcanization method).


3, storage: stored in dry environment at room temperature, valid for one year.
