Pultrusion Resin Manufacturer
High Speed. High Strength. Perfect Finish.
Specialized low-viscosity, high-reactivity formulations for FRP profiles, grating, and rebar.
Optimized for the Pultrusion Process
Pultrusion is a continuous molding process that demands specific resin characteristics. Unlike open molding, pultrusion requires resins with low viscosity for rapid fiber wetting and high reactivity for fast curing within the heated die.
As a specialized pultrusion resin manufacturer, Changyuan New Materials engineers formulations that maximize line speed without compromising mechanical properties. Our resins are trusted by manufacturers of fiberglass profiles, cable trays, and structural grating.
We offer a complete range including Orthophthalic, Isophthalic, and Vinyl Ester grades to meet varying structural and corrosion requirements.

Frequently Asked Questions
What is the ideal viscosity for pultrusion resin?
For most pultrusion processes, a viscosity between 300-600 cps (at 25°C) is ideal. This ensures the resin can fully penetrate tightly packed glass rovings before entering the heated die.
Can your pultrusion resin be used for carbon fiber?
Yes, we offer specialized vinyl ester and epoxy-based vinyl ester resins compatible with carbon fiber, providing superior wetting and mechanical properties for high-performance profiles.
Do you supply internal mold release agents?
Yes, we provide a complete package including compatible internal mold release agents (IMR) to ensure smooth processing and protect your dies.
