| High Light | Clear Unsaturated Polyester Resins ，Solvent Resistant Unsaturated Polyester Resins ，Solvent Resistant upr Polyester resin | ||
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
| 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% |
