Unsaturated Polyester Resins (UPR): High-Performance Thermosets for Composite Manufacturing

Unsaturated polyester resins are thermosetting polymers synthesized from dibasic acids (e.g., phthalic anhydride) and diols, featuring cross-linkable unsaturated bonds activated by initiators like MEKP. Engineered for versatility, our formulations deliver:

Rapid Room-Temperature Curing - 5-30 min gel time for hand lay-up, spray-up, and filament winding processes
Lightweight & High-Strength - Density 1.11-1.20g/cm³, FRP tensile strength ≥50MPa (4x lighter than steel)
Chemical Resistance - Withstands 10% acids/alkalis; isophthalic/bisphenol-A grades improve corrosion resistance by 50%
Electrical Insulation - Volume resistivity >10¹³Ω*cm for transformer encapsulation
Multi-Grade Portfolio - General-purpose, flame-retardant (LOI≥31%), and FDA-compliant food-grade resins

Five Key Industrial Applications Driving $2.1B Market Growth (2025-2030)

Industry	Critical Applications	Recommended Resin Type	Performance Edge
Construction	Cooling Towers/Corrosive Flooring	Isophthalic Resin (e.g., 191-type)	Weathering resistance ↑30%, HDT≥70°C
Transportation	Automotive Hulls/Wind Turbine Blades	Vinyl Ester Resin	Fatigue strength ↑200%, salt spray >1,000h
Electronics	PCB Substrates/Transformer Potting	Brominated Flame-Retardant Resin	UL94 V-0 certification (3mm thickness)
Chemical Processing	Acid Storage Tanks/Piping	Bisphenol-A Resin	Resists 98% H₂SO₄, HDT≥120°C
Consumer Goods	Artificial Stone/Buttons	Low-Shrinkage Crystal Resin (C7A)	Transparency >90%, shrinkage <0.1%

Selection Guide

Cost-Effective General Use -> Orthophthalic Resin (viscosity 300-600mPa*s)

Custom Carbon Fiber Fabric Sheets Woven For Industrial Applications

Turkey Jan 21.2026

Helpful (1)

As a manufacturer in Istanbul, we use WGSC’s Custom Woven Carbon Fiber Sheets for lightweight automotive chassis components. The 6K twill weave (240g/m²) was tailored to 1.2x3m sheets to fit our stamping molds, and its 1.75g/cm³ density cut vehicle weight by 35% vs. steel. The fabric’s compatibility with our polyester resins (zero delamination after 15,000 km road tests) impressed our R&D team. Mehmhet Yilmaz, our production manager, noted the Ankara warehouse’s JIT delivery—always arriving within 5 days—kept our assembly lines running smoothly. A game-changer for Turkish auto exports.

High Durability Heat Resistant Continuous Roving Fiberglass LFT Direct Roving

Philippines Jan 16.2026

Helpful (1)

At our marine engineering firm in Subic Bay, WGSC’s J860 LFT Roving revolutionized our offshore buoy mooring systems. The 1200tex profile’s exceptional saltwater resistance (no degradation after 18 months in 3.5% salinity) and 550MPa tensile strength exceeded ABS marine standards. The filament winding process ensured zero fiber breakage during injection molding, and the military-grade packaging survived typhoon-season shipping. Engr. Juan dela Cruz, our project lead, praised the 3-day delivery from Manila warehouses—critical for our 24/7 operations

High Strength Fiber Reinforced Plastic Panels Frp Plastic Sheet For Industrial Applications

Brazil Aug 28.2025

Helpful (22)

We used WGSC’s FRP Panels for the walkways and equipment platforms at our São Paulo ethanol plant—where constant steam and organic acids demand tough materials. The 8mm thick, 1000x2000mm panels (with a glass fiber-reinforced polyester core) handled 200kg/m² foot traffic and 80°C steam exposure without cracking. Their anti-slip surface (Ra 6.3 texture) improved worker safety, and the modular design let us assemble 200m² of platforms in 3 days. Mariana Silva, our project engineer, highlighted the São Paulo distributor’s JIT delivery—panels arrived just as our concrete bases cured. With a 20-year lifespan estimate, these panels are a smart investment for Brazilian agro-industrial sites!
