TECHNICAL INFORMATION

 

 

 

EFEP RP-4020 & 4040

 

 

FEATURES

 

EFEP RP-4020 and RP-4040 are fluoropolymers combining the excellent physical and chemical properties derived from ETFE together with the very low melting temperature characteristic of a conventional thermoplastic. These resins have a high transparency and adhere well to many kinds of plastics and inorganic materials (glass, metals) without adhesive or etching.

 

 

BENEFITS

 

EFEP RP-4020 and RP-4040 offer the following advantages for a wide range of applications found in the chemical processing, semiconductor and film industries:

 

• Very low processing temperature and excellent thermal stability 

 

• High transparency 

 

• Excellent chemical resistance 

 

• High purity 

 

• Excellent weathering 

 

• Improved heat sealing properties 

 

• Low mold shrinkage (injection molding) 

 

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

 

 

TYPICAL APPLICATIONS

 

Injection molding parts, mono- and multi-layer tubing, mono- and multi-layer films, bottles and containers.

SAFETY

 

When EFEP RP -4020 and RP-4040 resins are heated to temperatures above 280 °C, some decomposition products may be given off. These decomposition products may be harmful, and inhalation of these fumes must be avoided. Process equipment and working area must be adequately ventilated.

 

For further information, please refer to the material safety datasheet for these products and the Guide to the Safe Handling of Fluoropolymer Resins published by SPI Inc., 1801 K Street, NW, Suite 600K, Washington, DC, 20006-1301 (202-974-5200) or e-mail your questions to EFEP@daikin-america.com.
