Envalior

PBT - Pocan®

Pocan® is a high-quality brand of polybutylene terephthalate (PBT) and PBT blends crafted by Envalior. Pocan is known for its impressive resistance to heat and chemicals, outstanding electrical properties, strength and hardness. It is designed to cater to a wide range of industries, including automotive, electrical/electronics, lighting, household appliances, and sports & leisure.

Explore Pocan

  • High heat resistance, strength, and hardness
  • Outstanding electrical insulation properties, widely independent from temperature
  • Good chemical resistance and low tendency for stress cracking
  • Minimal moisture absorption and very good dimensional stability
  • Powerful elastomer-modified, and food contact approved grades
  • Excellent sliding properties and abrasion resistance
  • Unreinforced, glass fiber reinforced, and mineral-filled grades
  • Blends with acrylonitrile-styrene-acrylic ester copolymer (ASA) , Polyethylene terephthalate (PET) and polycarbonate (PC)
  • Specialties, optimized with regard  to flame retardancy (halogen and halogen-free),  hydrolysis resistance, tracking-resistance, laser marking and laser weldability

Pocan® portfolio highlights

Pocan E grades offer high tracking resistance

Especially for applications with a high need for miniaturization, such as connectors, our Pocan® E grades are well suitable. The Pocan E grades offer high tracking resistance (CTI A 600 / PLC 0) in combination with excellent long-term heat stability regarding electrical properties and good flowability. 

The PBT materials are available with different GF contents (e.g. Pocan B3225E (PBT GF20). Additionally, for parts operating in hot and humid environments we offer hydrolysis stabilized grades such as Pocan B3233HRE (PBT GF30 HR).

Furthermore, the Pocan® E-technology is available for several other Pocan® grades like the halogen-free flame retardant and hydrolysis resistant Pocan BFN4232HR (PBT-GF25-HR-V0).

Pocan XHR
