PC GF25 – 25% Glass Fiber Reinforced Polycarbonate Material

Glass Fiber Reinforced Polycarbonate – PC GF25

Balanced Structural Engineering Plastic for Injection Molding

PC GF25 is formulated by reinforcing polycarbonate (PC) with 25% glass fiber, creating a composite material that significantly enhances stiffness and load-bearing performance compared with unfilled PC. At the same time, it retains better flowability and surface appearance than higher glass fiber content grades like PC GF30, making it suitable for robust structural and housing applications with a balance of performance and manufacturability.

Material Composition & Glass Fiber Reinforcement Mechanism

PC GF25 uses short chopped glass fibers uniformly dispersed in a PC matrix. This enhances the material’s modulus, dimensional accuracy, and thermal stability.

Material Composition Overview

• Base Polymer: Polycarbonate (PC)

• Glass Fiber Content: 25% by weight

• Fiber Type: E-glass

• Optional Additives:

  • Heat stabilizers

  • Flame retardant (HB / UL94 V0)

  • UV stabilizers

  • Conductive or antistatic additives

• Color Options: Natural, black, customized

Compared to PC GF15, PC GF25 offers higher rigidity and heat resistance, while compared to PC GF30 it maintains better flow and appearance.

Core Advantages: Rigidity, Stability & Performance

FAQ

Q1: Is PC GF25 stronger than PC GF15?
Yes. PC GF25 provides higher rigidity and better load-bearing performance than PC GF15.

Q2: How does PC GF25 compare to PC GF30?
PC GF30 offers even higher stiffness, but PC GF25 typically provides better flowability and surface quality.

Q3: Is UL94 V0 available for PC GF25?
Yes. UL94 V0 flame-retardant versions can be supplied upon request.

Q4: Can PC GF25 be used for outdoor components?
Yes, with proper UV stabilizers and additives, UV-resistant grades are available.

Q5: Does glass fiber affect surface finish?
Glass fiber enhances rigidity but may slightly increase surface texture; design and mold finish control can mitigate this.
