Description

Flurine® 26502, 26602, 26702, 26703, 26802 and 26902

Flurine® 26502,26602,26702,26703,26802 and 26902 are middle Mooney Fluoroelastomer, which is comprised of vinylidene fluoride (VF₂) and hexafluoropropylene (HFP), frequently used in many industries including automotive, fluid power, appliance and chemical industries. They have good ductility and be excellent resistant to oils, fuels, aliphatic series, aromatic hydrocarbons, lubricants, and most mineral acids.

Process safety instructions

Store and use all fluoroelastomers only in a well-ventilated area.
Do not smoke in areas contaminated with dust from fluoroelastomers.
Avoid eye contact. After handling fluoroelastomers wash any skin that came in contact with the product with soap and water.
Potential hazards, including evolution of toxic vapors, exist during compounding or processing under high temperatures.
Before processing the fluoroelastomers, read and consult the MSDS, and follow all label directions and operation cautions.

Packaging and storage

FKM is packed in a plastic bag and then be put into a PVC bag with the net weight 25KGS. It must be stored in clean, cool, dry place.It must be stored in a clean, cool, and dry place. The storage life is one year from the date of production. It must be re-inspected if over one year and only can use if qualified.
It is transported as non-dangerous chemicals. Avoid excessive vibration and far away from pollution, sunshine and water during the transport.
