E-Glass Chopped Strands for Spray-Up Composites | PIONEER®
Durable, High-Strength Fiberglass Fiber Reinforcement
Upgrade your composites production with E-glass chopped strands, providing high-strength, lightweight, and consistent reinforcement for spray-up, hand lay-up, and thermoplastic compounding applications.
What Are PIONEER® E-Glass Chopped Strands?
PIONEER® HPM® EG-S is a premium E-glass chopped strand engineered for spray-up fiberglass composites and thermoplastic reinforcement. Manufactured using alkali-free glass fiber, these soft chopped strands disperse quickly and uniformly without clumping, enhancing tensile and flexural strength while supporting smooth, efficient processing for high-quality molded surfaces. Backed by over 22 years of expertise, PIONEER® ensures reliable, cost-effective reinforcement for composite manufacturers globally.
