Parker Chomerics PREMIER™ PBT-225 is a single pellet, polybutylene terephthalate (PBT) based, electrically conductive plastic that delivers superior reliability, making metal to plastic housing conversions possible for demanding electronics applications. PBT is known for its excellent chemical resistance thereby making it an ideal material for environments that have exposure to automotive type fluids (gasoline, motor oil, glycol 50/50 mix, brake and transmission fluids).

PREMIER PBT-225 is specially formulated to deliver excellent hydrolysis resistance, thereby improving long term aging performance when exposed to typical heat and humidity conditions found on automotive applications. It provides up to 75° C continuous use temperature rating

The single pellet composition of PREMIER PBT-225 provides a more reliable solution to traditional two pellet blend (also known as “salt and pepper blend”) conductive resin systems. The easy processing of PREMIER PBT-225 allows for uniform filler dispersion and, as a result, tightly controlled electrical and mechanical performance throughout complex geometries. The improved hydrolysis resistance, electrical properties and manufacturability of PBT-225 makes it a superior choice for plastic housing.

This product was specifically developed to provide a more reliable solution to traditional cube blend conductive resin systems and a more efficient alternative to metal and non-conductive plastic housings.

The cutting-edge processing of PREMIER PBT-225 into a single pellet composition allows for uniform material dispersion and a tightly controlled conductive material ratio throughout complex geometries, delivering a matrix of polymer and conductive filler.
