PLEXIGLAS® Hi-Gloss NTX-8
PMMA(亚克力)
罗姆化学(原赢创)(Rohm/Roehm Chemical)
产品描述
PLEXIGLAS® NTX-8 is an amorphous thermoplastic molding compound (PMMA).
In addition to the typical properties of PLEXIGLAS® molding compounds like:
• high mechanical strength, surface hardness and abrasion resistance
• very good weather resistance
• very good polishable
PLEXIGLAS® NTX-8 does have the following features:
• increased wipe resistance
• significantly increased flowing properties
• increased demoulding
• less tendency to create weld lines
PLEXIGLAS NTX-8 is available in coloured state only.
Application:
PLEXIGLAS® NTX-8 is particularly suitable for injection molding of technical components. Owing to ist superior brilliance, high-gloss (Class A) black surfaces can be obtained without an expensive painting process. Due to the improved flowing properties NTX-8 is suitable for sandwich molding of e.g. B-pillar covers or decorative trim parts for automotive interior.
