| Description |
Fluoroelastomer FKM Terpolymer Gum 246 series are the terpolymer of vinylidenefluoride, tetrafluoroethylene and hexafluoropropylene. Because of its high fluorine content, its vulcanizedrubber has excellent anti oil property and high thermal stability. It also has good mechanical property and can be used in 275 ℃ for a long time, in 320℃ for a short time. The property of anti oil and anti acid is better than F23, resistance of FKM246 to oil, ozone, radiation, electricity and flamer is similar with FKM26. |
| Application |
Widely used in aerospace, automotive, machinery, petrochemical, and other fields. For example, the aircraft static/dynamic seals materials of hydraulic system and lubrication system; used in drilling equipment and oil pipelines; the chemical industry for equipment, flexible pipe connections, liner of pump or corrosion-resistant sealing material, made of pipes to carry solvents or other media, such corrosion. |

| 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. |
