HENGLI HC-70T
- Low viscosity high flow polycarbonate resin
- Heat stabilized transparent PC
- Excellent optical clarity with low haze
- Ideal for thin-walled injection molding
- Stable and high productivity processing
Product Overview
HENGLI HC-70T includes two low-viscosity, heat-stabilized polycarbonate (PC) grades: HC-70TA and HC-70TB.
These grades are designed for injection molding applications requiring high flowability, excellent optical clarity and thermal resistance.
HC-70T grades are optimized for thin-walled parts, complex mold designs and high-productivity manufacturing, making them suitable for transparent components used in automotive, electronics and industrial applications.
Key Properties
Low viscosity with very high melt flow for thin-walled molding
Heat stabilized formulation for elevated temperature performance
Excellent optical clarity with high light transmittance
Low haze for transparent and see-through components
Good impact strength and mechanical balance
Consistent particle quality for stable processing
Available Grades
HC-70TA
Higher light transmittance
Lower yellow index
Suitable for high-clarity and high-flow applications
HC-70TB
Balanced optical and mechanical performance
Slightly higher yellow index
Suitable for general thin-walled transparent components
Typical Applications
