Features & Benefits
Excellent for Blow Molding
LG ABS BM662 is specifically formulated for blow molding processes, ensuring consistent flow and parison control for creating complex, hollow parts like spoilers with high dimensional stability and uniform wall thickness.
Withstands High Temperatures
This ABS resin maintains its structural integrity in high-heat environments, with a Heat Deflection Temperature of 95°C. This prevents deformation when exposed to summer sun or engine heat, ensuring long-term part performance.
Superior Paintability and Impact Resistance
The surface of BM662 provides excellent adhesion for paints and coatings, allowing for a flawless, durable finish. Combined with high notched impact strength, it helps parts resist chipping, cracking, and abrasion.
