PC GF45 Glass Fiber Reinforced Polycarbonate Material

Glass Fiber Reinforced Polycarbonate – PC GF45

Ultra-High Rigidity Engineering Plastic for Structural Components

PC GF45 is formulated by incorporating 45% glass fiber into a polycarbonate (PC) matrix, resulting in a material with superior stiffness, strength, and thermal endurance compared with lower fiber content grades. While maintaining the impact resistance and processing characteristics of PC, this grade provides excellent load-bearing capability and dimensional integrity for heavy-duty engineering parts.

Material Composition & Reinforcement Structure

PC GF45 combines short chopped glass fibers with the PC matrix through precision compounding. This creates an internal load-bearing network that significantly amplifies mechanical performance.

Material Composition Overview

• Base Polymer: Polycarbonate (PC)

• Glass Fiber Content: 45%

• Fiber Type: E-glass

• Optional Additives:

  • Heat stabilizers

  • Flame retardant (HB / UL94 V0)

  • UV stabilizers

  • Conductive / Antistatic additives

• Color Options: Natural, black, customized

Compared with PC GF25 and PC GF30, PC GF45 delivers much higher modulus and strength, making it suitable for high-stress structural applications.
