Plastic Enclosures

B&R Enclosures supply a range of enclosures that use different plastics and are suitable for a variety of different applications.
For more information on which type of material to choose, please see our pages on chemical resistance (pdf) and plastic flammability.
Materials used in B&R Enclosure’s range include: –

  • Noryl – Noryl is a blend of polyphenylene oxide (PPO) and polystyrene (PS) that was developed by General Electric Plastics in 1966. It has good electrical resistance and is widely used for electrical enclosures
  • Polyester – Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term “polyester” as a specific material most commonly refers to polyethylene terephthalate (PET).
  • GRP/Polyamide – A polyamide is a polymer containing monomers of amides joined by peptide bonds. They can occur both naturally, examples being proteins, such as wool and silk, and can be made artificially through step-growth polymerization, examples being nylons, aramids, and sodium poly (aspartate).
  • Glass filled polyester – As detailed for polyester above, but with additional glass fibres for strength and rigidity at larger sizes.

Our enclosure materials are as follows:
