NORYL LPN170HG resin is a non-reinforced blend of polyphenylene ether (PPE) + polystyrene (PS) designed for high heat resistance, low density, high gloss, low outgassing and good dimensional stability performance. This extrusion and injection moldable grade carries HDT 170°C, special gravity 1.07 g/cm3. This grade is capable for physical vapor deposition with good light distribution and high reflection rate. LPN170HG is targeted for automotive headlamp reflector, bezel, trim, light shielding and other high surface quality / high heat resistance demanded components.
All colors are customizable. Refer our ColorXpress tool to check color availability
