Product description
Fluoroelastomer FKM copolymer Gum-26 series are the copolymer of vinylidenefluoride and hexafluoropropylene , whose fluorine content is over 66%. After valcanizing process,the products have excellent mechanical performance, outstanding anti oil property(fuels, synthetic oils, lubricating oils) and heat resistance.
Execution standard Q/0321DYS 005-2015

Technical Index

Product Use
Widely used for manufacturing washers, gaskets, O-rings, V-rings, oil seals, diaphragms, rubber pipes, cable sheaths, heat insulation cloth, valve plates, expansion joints, rubber rolls, coatings and pasty room temperature vulcanization putties in occasions resisting high temperature, auto fuel, lubricating oil (synthetic oils), fluid (various non-polar solvents), corrosion (acid, alkali), strong oxidizer (oleum), ozone, radiation and weathering.

Cautions
1. Fluoredastomer copolymer has good heat stability under 260℃. It will generate trace decomposition if being put at 260?300℃ for a long time, and its Secomposing speed accelerates at above 320℃, the decomposition products are mainly toxic hydrogen fluoride and fluorocarbon organic compound. When raw fluorous rubber encounters fire, it will release toxic hydrogen fluoride and fluorocarbon organic compound.
2. Fluorous rubber cannot be mixed with metal powder such as aluminum powder and magnesium powder, or over 10% amine compound, if that happens, temperature will arise and several element will react with FKM, which will damage the equipment and operators.
Package ,transportration and storage
1. Fluorous rubber is packed in PE plastic bags , and then loaded into cartons, the net weight of each carton is 20kg.
2. Fluorous rubber is stored in clean, dry and cool warehouse. It is transported according to non-hazardous chemicals, and should keep away from pollution source, sunshine and water during transportation.
