Product Characters

• FKM JHF26 series (commonly known as 2# gum) is an elastomer synthesized by copolymerization of vinylidene fluoride (VDF), hexafluoropropylene (HFP);
• The product is non-toxic, tasteless, incombustible, self-extinguishing and with good storage stability. It could be soluble in low-molecular-weight ketone or ester;
• Vulcanized rubber has good mechanical properties like heat, oil, solvent, flame, and weather resistance, electrical insulation.

Main Application

• The product is widely used in the areas of high temperature resistant, fuel resistant (aviation fuel, automotive fuel), lubricant resistant (various synthetic oil), fluid resistant (various non-polar solvents), corrosion resistant (acid, alkali), strong oxidant resistant (fuming sulfuric acid, etc.), ozone resistant, radiation resistant and weather resistance;
• It is also used to make gaskets, O-rings, V-shaped bodies, skeleton oil seals, diaphragms, hoses, cable sheaths, heat-insulating cloths, valve plates, and expansion and contraction, joints, rubber rollers, coatings, paste-like room temperature vulcanized putties, etc.

Packing, Storage & Transportation

• 5kg/bag, 5 bags/carton;
• Packed in a polyethylene bag, stored in a clean, dry and cool warehouse;
• It is transported as non-hazardous chemicals and should be kept away from pollution, sunlight and water during transportation;
• The storage period of the product is one year from the date of production. If it exceeds the storage period, it can be re-inspected according to the company’s inspection standard. If it meets the requirements, it can still be used.
