EMS-Grivory Grilamid® TR 90 NZ PAMACM12-I
Categories: Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 12 (PA12)

Material Notes: Product description: Grilamid TR grades are transparent thermoplastic polyamides based on aliphatic and cycloaliphatic blocks. Grilamid TR 90 NZ offers a variety of interesting properties such as:
  • outstanding impact resistance even at low temperatures
  • very high flexural fatigue strength
  • good chemical- and stress-crack resistance
  • high UV resistance
  • can be colored in transparent as well as opaque colors
Grilamid TR 90 NZ shows reversible thermotropic transparency. The transparency continuously decreases during heating from room temperature to about 70°C. At 80°C the material is opaque. Grilamid TR 90 NZ is suitable for production of optical and technical demanding parts in the application fields of:
  • Optics
  • Electro
  • Electronics
  • Automotive
  • Mechanical engineering
  • Domestic appliances
