Polycarbonate: Techno Brief

This technology profile features various key facts about polycarbonate. It deals with various significant properties of polycarbonate, its strengths, limitations, applications in different markets and processing guidelines.

Polycarbonate

  • It is one of the most versatile and widely used thermoplastic polymer manufactured by the reaction of bisphenol A and phosgene.
  • It is transparent, hard, stiff and consists of carbonate groups.
  • Shows excellent mechanical properties.
  • Thermally stable upto 135°C and exhibit good impact strength.
  • Offer poor scratch and chemical resistance which limits its use in several applications.
  • Shows excellent compatibility with certain polymers. Therefore, it is widely used in blends. Some of these characteristics match with PMMA.
  • It can be processed by extrusion, injection molding, blow molding etc.
  • Major applications include : automotive, appliances, household/domestic articles, electronics, etc.
