Features & Benefits
Superior Impact Strength at Low Temperatures
With high Izod and dart impact values even at -30°C, LG9000 Resin ensures your products remain tough and crack-resistant in challenging environments, from freezing winters to refrigerated applications.
Excellent Heat Resistance for Assembled Parts
Its high Heat Deflection Temperature (HDT) allows parts to withstand the high heat of assembly processes, such as soldering or hot environments, without warping or losing structural integrity.
Consistent Low-Gloss, Aesthetic Finish
This LG9000 plastic material delivers a uniform low-gloss surface straight from the mold, ideal for consumer electronics and automotive interiors where a premium, non-reflective look is critical, saving on paint and finishing costs.
Use & Application
- Automotive Interiors: Durable, low-gloss components
- Consumer Electronics: Housings for monitors, printers, and home appliances
- Industrial Equipment: Housings and covers for machinery
