Unsaturated Polyester Resin for Pultrusion

This Unsaturated Polyester Resin supports continuous, industrial-scale pultrusion lines with consistent dimensional accuracy and smooth linear profile formation. Applications include FRP structural profiles, ladder rails, cable trays, pultruded rods, rebar, window and door frames, cooling tower profiles, walkway gratings, wind turbine blades, antenna elements, marine components, fencing profiles, cross-arms, and corrosion-resistant industrial beams. Ideal for construction, infrastructure, energy, transportation, electrical support systems, and composite architecture.

Composition typically include orthophthalic or isophthalic unsaturated polyester resin, styrene monomer, MEKP initiator, cobalt accelerator, glass-wetting agents, cure-rate modifiers, low-shrink additives, impact-resistance boosters, UV stabilizers, and heat-resistant fillers. High strength pultrusion grades are designed for maximum glass content with minimal void formation.
