FLEX NORYL™ Resin WCD855

1 of 26 products in this brand

FLEX NORYL WCD855 resin is a thermally stable, flexible, and flame-resistant material composed of PPE and TPE, with low water absorption and good electrical properties, making it well suited for consideration in AC cable jacket applications.


It is a non-reinforced, extrudable, flexible material made from a blend of Polyphenylene Ether (PPE) and Thermoplastic Elastomer (TPE).


This resin has the following properties:

  • High flame resistance: It contains non-halogenated flame retardants and meets the UL 1581 VW-1 requirements
  • Good electric properties
  • Low specific gravity
  • Excellent thermal stability
  • Low water absorption


It is well suited for evaluation in AC cable jacket applications that require a UL62 rating at temperatures of 90°C or 105°C and is available in black color.


FLEX NORYL WCD855 resin has a Shore A Hardness of 85.


FLEX NORYL WCD855 resin is typically processed using standard extrusion equipment. UL 1581 testing is performed on 2.0mm wire with a 0.12mm x 20 stranded copper conductor.


This product does not contain PFAS intentionally added during SHPP’s manufacturing process. Each user is responsible for evaluating the presence of unintentional PFAS impurities.
