As markets of, for example, electrical and electronics, automotive, appliances and energy storage, demand higher voltages and smaller, lighter components, materials that balance safety and performance have become increasingly important.

Teknor Apex introduces Crealen, a glass-filled, halogen-free flame-retardant polypropylene (HFFR PP) product series to meet these challenges. It offers very good flammability ratings and glow wire ignition performance while maintaining its mechanical properties even after exposure to moisture and acid.

Utilizing an innovative halogen free flame-retardant technology, these grades deliver UL94V0 performance at 1.5mm and achieve UL5VA at 3.0mm, while maintaining high mechanicals properties.

Crealen solutions utilize halogen free flame-retardant technology to deliver UL94V0 performance at 1.5mm and pass UL5VA at 3.0mm.

This unique balance of properties makes them suitable for a wide range of demanding applications, including thin-wall housings, connectors, brackets, shields, etc. in eMobility, power tools, outdoor power equipment appliances, and electronics.

In contrast to more commonly used glass filled flame retardant grades based on polyamides (such as PA 6) or polyesters (such as PBT), Crealen HFFR PP products offer a wide range of benefits, such as inherent resistance to moisture absorption, high adhesion to TPEs and TPVs in 2-K molding, and significantly lower density.

Due to these unique performance characteristics, they are good for applications with that require resistance to acid exposure or for use in high humidity environment.

“Specialty Crealen HFFR PP compounds offer enhanced performance and unique characteristics, that enable electrical system engineers to successfully replace typical engineering plastics, by unlocking design potential and enabling systems cost savings,” emphasized Pratik Shah, Vice President Engineering Plastics BU.

"We plan to expand this product series with further innovation and launch products suitable for extrusion processing for manufacturing of wire & cable products, conduits, tubing, and sheet applications.”
