What Kind Of Plastic Is The Insulating Material Of Heavy-duty Connectors Made Of?

These materials can be either thermoplastic or thermosetting, and the specific materials should be selected according to actual needs.

Available thermoplastics include polycarbonate PC, reinforced PC, reinforced PET, PBT, PCT (cyclohexyl terephthalate), PTT (polypropylene terephthalate), PA6, PA66, PA6T, PA9T, PA46, PA612, PPS (polyphenylene sulfide), LCP, PASF (polysulfone) and PEI.

Available thermosetting plastics include phenolic resin (PF), polydiallyl phthalate (DAP), epoxy resin (EP) and unsaturated polyester (UP).

For different applications, the focus of specific materials is different.

For Heavy Duty Connector, mineral-filled phenolic plastics were mainly used in the past, but due to low production efficiency, they have been replaced by new thermoplastics such as PA, PC, reinforced PC and polysulfone. Most of the white contacts of our common mobile phone chargers, HA Connector Insert, are made of PC or enhanced PC.

DAP materials should be selected for H48B Connector Hood & Housing used under hot and humid conditions.

For electronic connectors with high sealing requirements, such as submarine cable connectors, sulfur-free or low-sulfur rubber with good dielectric properties should be selected, such as silicon-containing nitrile rubber or fluororubber.
