| Description |
Low Compression Set Fluorosilicone Rubber Compound FS-R8400 is translucent uncatalyzed fluorosilicone rubber base mixed evenly with some kinds of fillers and additives. Its compression set is lower than that of normal fluorosilicone rubber compound. |
| Appearance |
Translucent, smooth surface, no visible impurities |
| Application |
Used as sealing materials to resist petroleum oil, lubricant oil, hydraulic oil, transformer oil, and non-polar chemical reagents in low temperature and/or high temperature environments.
Used to produce molded, extruded, and calendered fluorosilicone parts, such as O-rings, gaskets, sealing rings, oil seals, sealing strips, sensor materials, diaphragms, membranes, and clips for fluorosilicone gaskets and pipes. |
| Shelf Life |
1 year |
| Storage |
Transported as non-dangerous substance.
Keep it in good condition of packing during transportation.
The product should be stored in a dry and ventilate place at room temperature.
Avoid from acid, alkali chemical materials and other impurities. |
