Altuglas® HT 121
PMMA(亚克力)
阿科玛Altuglas (Arkema)
产品描述
Highest heat and scratch resistance
Pure acrylic resin intended for both injection and extrusion exhibiting unique features:
> Highest Temperature Resistance of all PMMA grades available on the market (increases productivity by reducing cycle times) with a Vicat B50 of 121°C vs 108°C max in the regular range. Altuglas® HT 121 can indeed sustain 100°C in a continuous use.
> Highest Scratch Resistance of all PMMA grades available on the market for a premium aesthetic retention.
> Incredible clarity with 92% in light transmission and 0.5% in haze.
> Outstanding weatherability and UV resistance (AMECA certification).
> Typical PMMA ease of colouring.
Altuglas® HT 121 is typically used in sensitive tail light and cluster lens designs, household appliances and electronic device displays and any application with stringent combinations of heat/optics/hardness/UV ageing demands.
For applications with more stringent purity requirements (e.g. cluster lens), QCB quality material is also available. For visually clear applications requiring higher UV screening (e.g. automotive medallions), the UVP3 version of Altuglas® HT 121 is suitable.
