ABS CHIMEI Taiwan PA‑758
ABS CHIMEI Taiwan PA‑758
Product Introduction ABS CHIMEI Taiwan PA‑758 is a high‑flow, high‑transparency MABS resin (transparent ABS). MMA component is added to adjust the refractive index of the base material to match that of rubber elastomer, so as to achieve transparent effect.
Main Applications
Home‑Appliance Products: Air‑conditioner panels, washing‑machine top covers, vacuum‑cleaner housings.
3C Product Housings: Shells for computers, mobile phones and other electronic products.
Stationery & Daily Articles: Ball‑point pens, toys, gear covers.
Other Applications: Certain automotive interior and exterior parts (non‑primary application).
