Chomerics Premier PBT-225

Parker Chomerics released Premier PBT-225 in March of 2017. Since then, our team here at KRA Fab has found this new material to be a reliable choice that offers big improvements over previously available plastic housing products. Read on to learn more about PBT-225 and why we use it.

What is Chomerics Premier PBT-225?

This single-pellet electrically conductive plastic is polybutylene terephthalate (PBT)-based. PBT-225 conductive plastic pellets offer EMI shielding and are ideal for making metal to plastic housing conversions in electronics applications.

Why use Chomerics Premier PBT-225?

Chomerics PBT-225 was designed as a better alternative to the previously standard cube-blend conductive resin systems and metal-coated plastic housings.

Parker Chomerics estimates that, compared to aluminum, metal-to-plastic conversions reduce housing weight by 35% and cut costs by 65%. (They attribute the cost savings to cutting out secondary operations, including assembly and machining.)

One of the biggest benefits of PBT-225 is that it eliminates mixing to ensure a uniform material dispersion. This makes for a more uniform matrix of the conductive filler. Single-pellet plastics are also easier to control for more precision when working in electronic and mechanical applications.

Other helpful properties include hydrolysis resistance and long-term reliability, which make it a dependable choice for a variety of designs. 

It’s also consistent with Six Sigma standards for automotive industry tolerances.
