MABS LG Chem TR‑557
MABS LG Chem TR‑557
MABS LG Chem TR‑557 is a high‑transparent (transparent ABS) resin. Featuring excellent transparency, high rigidity, high flowability and good impact resistance, it is one of the ideal choices for manufacturing transparency‑required products.
Main Applications
Electrical‑electronic: vacuum‑cleaner components, air‑conditioner panels, copier parts, telephone components, computer housings. Home appliances: refrigerator internal parts, humidifier water tanks, mixer housings. Automotive: automotive interior trims (instrument panels, decorative strips), window‑related components requiring transparency and strength. Lighting: lamp housings and lamp‑shades. Others: stationery, toys, cosmetic packaging.
