HENGLI HC-31RT
- Medium viscosity polycarbonate resin
- Heat stabilized blue tint PC
- High optical clarity with low haze
- Excellent impact resistance
- Balanced flow for injection molding
Product Overview
HENGLI HC-31RT includes two medium-viscosity, heat-stabilized polycarbonate (PC) grades: HC-31RTA and HC-31RTB.
Both grades feature a light blue tint and are designed for injection molding applications requiring balanced flow behavior, high impact strength, excellent optical clarity and thermal stability.
HC-31RT grades are suitable for transparent components used in automotive, optical and industrial applications where both appearance and heat resistance are important.HENGLI HC-31RT
