Key Products

Zytel® (PA66)

Zytel® is proven across diverse industries, including automotive, electrical and electronics, industrial, consumables, and oil and gas. Each nylon variant has been expertly developed to meet a wide array of performance requirements, ensuring reliable solutions for your specific needs.

Crastin® (PBT)

Crastin® is the leading brand name of PBT chemistry from Celanese, known as Polybutylene Terephthalate (PBT). Crastin PBT is an engineering thermoplastic polyester used in automotive, medical, consumer, electrical and electronics industries.

Rynite® (PET)

Rynite® (PET) is an excellent alternative to die-cast metals and thermosets, particularly in applications requiring durable electrical and electronic performance at elevated temperatures. Rynite® is well-suited for use in electrical devices, photovoltaic panels, switches, and more.

Hytrel® (TPC-E)

Hytrel® is a TPC-ET thermoplastic polyester elastomer based on block copolymer technology.
Hytrel® combines the flexibility of rubber with the strength and processability of plastic, making it an exceptionally versatile polymer for a wide range of applications.

Celcon-Copolymer

Copolymer (POM) also known as acetal or polyacetal, is a highly crystalline engineering plastic that offers low friction, excellent wear resistance, and high stiffness. It combines strength and toughness with resistance to solvents and fuels, making it ideal for precision parts.
