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).
