Trinseo TYRIL™ 905 Styrene-Acrylonitrile
Categories: Polymer; Thermoplastic; SAN Polymer

Material Notes: TYRIL™ styrene-acrylonitrile (SAN) resins are designed to offer superior chemical resistance, strength, hardness and dimensional stability in a broad range of product applications. The key property of TYRIL 905 is its superior water-clear clarity compared to other SAN resins and a high thermal stability that results in consistent color (reduced yellowing). TYRIL 905 is designed for applications demanding chemical and heat resistance and offers good processability. TYRIL 905 represents a technology breakthrough in trace-color reduction. Its thermal stability and exceptionally low base color make it a product especially suited for self-coloring. The UV-stabilized version exhibits excellent weatherability, suitable in particular for lighting applications.

Applications:

  • Large appliances: transparent kitchen parts
  • Lighting applications: louvers and covers
  • Automotive: taillight lenses and reflectors
  • Cosmetic packaging: water-clear, thick-wall applications
