产品描述

Altuglas® V 825T both injection and extrusion resin with good flow and high heat resistance.  For applications with more stringent purity requirements (e.g. cluster lens), QCB quality material is also available.

Altuglas® V Resins Non impact-modified resins exhibit the following features:

> Greatest optical performances of all existing thermoplastic materials (92% LT / 0.5% haze) to ensure crystal sparkle and brilliance even at high thickness,

> Outstanding resistance to mechanical damage and discoloration by ultraviolet rays; years of outdoor exposure have no visible effect on Altuglas® PMMA,

> Unsurpassed surface hardness (Rockwell M-Scale) and hence scratch resistance ensuring a lasting premium look, 

> Higher heat resistance than impact-modified grades (Vicat B50 up to 108°C),

> Good stiffness,

> Delicate feel and sound, 

> Ease of colouring (PMMA based MB required for non opaque colours to avoid optical defects).

Altuglas® V Resins have, over the years, demonstrated their outstanding performance and benefit and are thus  widely used today in the most demanding applications such as automotive tail lights and instrument clusters, light fittings, household appliances, mobile phone displays, optical parts and cosmetic jars, etc. For both injection and extrusion, no matter how critical the part is, you will find an Altuglas® V Resin to address your processing needs through the wide MFI range (from 2 to 14.5) and custom lubrications available.
