Description

Description

Flurine®PC series is peroxide-cured fluoroelastomer, copolymerized with vinylidene fluoride (VF2), hexafluoropropylene (HFP), and bromine-containing or iodine-containing fluoroolefin monomers.

Usually used in automotive, hydraulic applications, electrical and chemical industries. It has excellent processability and mechanical properties, excellent resistance to high-temperature steam. In addition, only a very short curing time is required.

Process Safety Instructions

1）Store and use all fluoroelastomers only in a well-ventilated area.

2）Do not smoke in areas contaminated with dust from fluoroelastomers.

3）Avoid eye contact. After handling fluoroelastomers wash any skin that came in contact with the product with soap and water.

4）Potential hazards, including evolution of toxic vapors, exist during compounding or processing under high temperatures.

5）Before processing the fluoroelastomers, read and consult the MSDS, and follow all label directions and operation cautions..

Packaging And Storage

1）Fluoroelastomers be packed in PVC bags in the shape of rubber film, each bag weight 5KGS, and finally be put into a carton. Each carton contains 5 bags with net weight 25KGS.

2）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.

3）It is transported as non-dangerous chemicals. Avoid excessive vibration and far away from pollution, sunshine and water during the transport.
