| Description |
Fluorous rubber (FKM-26), commonly called 2# rubber, is white elastomer and copolymer of VDF and hexafluoropropylene, with fluorine content of over 66%. The product processed and vulcanized by raw fluorous rubber (26), featured by good mechanical property and excellent oil resistance (fuels, synthetic oils, lubricating oils) and heat resistance, is an indispensable material for modern aviation, rocket, space flight, and other top technologies and industries. |
| Application |
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 andpasty room temperature vulcanization putties in occasions resisting high temperature, fuel (aviation gasoline, auto fuel), lubricating oil (synthetic oils), fluid (various non-polar solvents), corrosion (acid, alkali), strong oxidizer (oleum), ozone, radiation and weathering. |

| Notes |
1. Raw fluorous rubber has good heat stability under 260℃. It will generate trace decompositionif being put at 260 ~ 300℃ for a long time, and its decomposing speed accelerates at above 320℃, and decomposition products are mainly toxic hydrogen fluoride and fluorocarbon organic compound. When raw fluorous rubber encounters fire, it will release toxic hydrogen fluoride andfluorocarbon organic compound.
2. Fluorous rubber cannot be mixed with metal powder such as aluminum powder and magnesiumpowder, or over 10% amine compound, if that so, it will seriously damage the mixer and operator due to temperature rise and drastic reaction of partial elements and fluorous rubber during mixing. |
| Packaging |
1.Fluorous rubber is packed in PE plastic bags in the form of film, and then loaded into cartons, and each carton has net weight of 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 duringtransportation.
3.The product has one year of shelf time since the date of production, and can be reinspected according to our company standard if exceeding the shelf time and used if meeting requirements. |
