TECHNICAL INFORMATION

 

 

 

 

EFEP RP-5000

 

FEATURES

 

EFEP RP-5000 is a fluoropolymer combining the excellent physical and chemical properties derived from ETFE together with a low processing temperature that is more compatible with engineering resins and conventional thermoplastic polymers. This resin adheres well to many kinds of plastics and inorganic materials (glass, metals) without adhesive or etching.

 

BENEFITS

 

EFEP RP- 5000 can be easily co -extruded into multi-layer tubing or films and offers the following advantages for a wide range of applications found in the automotive, oil and gas, chemical processing, semiconductor and film industries:

 

• Very good permeation resistance to hydrocarbons 

 

• Excellent chemical resistance 

 

• High purity 

 

• Improved heat aging resistance 

 

• Co-extrusion with other resins (nylons, EVOH, modified PE, and ETFE) without adhesive or etching 

 

• Superior adhesion strength 

 

• Excellent weathering 

 

• Cold impact resistance 

 

TYPICAL APPLICATIONS

 

Mono- and multi-layer tubing, mono- and multi-layer films and injection molding parts.
