Thermoplastic Application

Weipren® Chlorinated polyethylene (CPE) finds use in thermoplastic applications, such as wire and cable jackets, rigid foam, injection molded goods, sheet/films, fabric coatings and adhesives seals.

Weipren® CPE blends well with many types of plastics such as Polyethylene, EVA, and PVC. Such blends can be formed into final products with adequate dimensional stability without the need of vulcanization.

The excellent additive/filler acceptability characteristics of Weipren® CPE can provide a benefit in blends where compound performance and economics are emphasized. Examples of these products are flame retardant Wire and Cable jackets and flexible magnets.

CPE is unique in its ability to compatibilize thermoplastic blends, based on its intermediate status between polar (e.g. PVC) and non-polar (e.g. PE) polymers.

CPE can be used as a process aid in rigid PVC foam applications as a partial replacement for acrylics. CPE can also be used as an additive in injection molding applications of a variety of thermoplastic resins.

Impact Modification for Rigid Vinyl Applications

Weipren® Chlorinated polyethylene (CPE) modifiers provide excellent impact resistance and ductility to the entire range of rigid PVC applications, including vinyl siding, fence, window profiles, and pipe. The range of use extends to PVC cap stocks, based on proven weatherability of CPE-modified compounds. Specialized Weipren® CPE grades provide enhanced efficiency with an excellent combination of processing characteristics.

• Vinyl Siding: CPE is the modifier of choice for cost/performance efficiency in vinyl siding substrate, providing toughness at low temperatures, ductility, and a high capability for filler acceptance. Good weatherability for CPE-modified compounds extends the range of application to the siding capstock.

• Fence/Deck: CPE provides excellent impact properties, filler acceptance, and ductility in vinyl fence substrate, and can also be utilized in capstock applications.

• Window Profiles: CPE is used extensively, alone or in blends with acrylic impact modifiers, to achieve a desirable combination of ductile impact and processing performance. CPE-modified profiles are characterized by improved low temperature properties and corner-weld strength
  

• Pipe: CPE finds use in pipe applications, typically in specialty PVC pipe, CPVC pipe, electrical conduit, and any highly-filled compounds in this category.
