 Covestro Bayblend W 85 XF PC/ABS Description 

Bayblend W 85 XF is a composite material consisting of polycarbonate and acrylonitrile-styrene-acrylate terpolymer produced by Covestro AG. It is also known as"PC/ASA material"or"PC alloy"and, due to its excellent weather resistance, is commonly used in the manufacture of products intended for outdoor use.

Covestro Bayblend W 85 XF PC/ABS Advantage

  • High weather resistance, The key difference between Bayblend W 85 XF and conventional PC alloys is that it incorporates ASA, a high-performance polymer with excellent weather resistance that can withstand UV radiation, rain, humidity, and high temperatures. Compared to PC/ABS materials, it is better suited for manufacturing products intended for outdoor use, particularly automotive exterior trim.
  • Heat resistant.  the vicat softening temperature of Bayblend W 85 XF reached 130℃，temperature of deflection under 1.8 MPa reached 109℃, is more heat-resistant than standard ABS materials and performs better in outdoor environments exposed to direct sunlight.
