1, Product introduction: translucent or milky white high resilience type fluoro-silicon rubber, good physical properties and processing properties, with good resilience, low pressure change, vulcanization speed and good flow characteristics, suitable for making a variety of sealing 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 required shape, and then to the molding machine to press vulcanization molding (customers should determine the 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.

1. The vulcanizing agent is 2, 5dimethyl-2, 5di-tert-butyl hexane peroxide (DBPH), and the dosage is 0.8gDBPH/100g premixed glue.


2, the production of test film: a stage vulcanization: 170℃*10Min, two stage vulcanization: 200℃*4H. 3, meet the heat resistance requirements need to add heat resistant additives.
