​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)9
  • ​Food Contact​ → Hydrogenated Bisphenol-A (Pb migration <5ppm)4
  • ​Dynamic Loads​ → Vinyl Ester Resin (impact strength >15kJ/m²)5

​Technical Specifications (ISO/GB Compliance)​​

​Parameter​ ​191 General-Purpose​ ​197 Bisphenol-A​ ​FX-3520 Isophthalic​ ​Test Standard​
​Viscosity @25°C (mPa·s)​​ 300-600 350-650 600-1,000 GB/T 7193
​Gel Time @25°C (min)​​ 9-15 8.4-15.6 15-30 GB/T 7193.6
​Tensile Strength (MPa)​​ ≥50 ≥80 ≥55 GB/T 2567
​Flexural Strength (MPa)​​ ≥85 ≥120 ≥95 GB/T 2570
​HDT (°C)​​ ≥70 ≥115 ≥135 GB/T 1634
​Barcol Hardness​ ≥36 ≥45 - GB/T 3854


​Military-Spec Packaging & AIoT Storage​

​Triple-Barrier Protection System​

​Component​ ​Technical Specification​ ​Certification​
​Primary Container​ UV-blocking HDPE drum (220kg, ≥99% opacity) ISO 15750
​Moisture Barrier​ Al-foil laminate (<0.1g/m² WVTR) MIL-STD-2073
​Shipping Crate​ Honeycomb corrugated box (12kN crush) ISTA 3E

​Smart Traceability:

  • ​Color Coding: General (Blue █) │ Food-Grade (Green █) │ Flame-Retardant (Red █)
  • ​NFC Digital ID: Tap for real-time SDS & batch data

​Technical Validation & Global Certifications​

  1. ​Extreme Testing: Bisphenol-A resin endures 120°C for >500h without failure
  2. ​Eco-Compliance: REACH Annex XVII & RoHS 3 full compliance
  3. ​Field Proven: 191 resin used in Three Gorges cooling towers (8-year zero penetration)

​


​Why This Converts Industrial Buyers?​​

✅ ​Problem-Solution Fit: "UL94 V-0 certification" directly addresses fire safety regulations in construction/transport
✅ ​Data Transparency: Full ISO/GB test parameters build technical credibility
✅ ​Supply Chain Security: NFC traceability simplifies compliance audits
✅ ​Market Authority: Cites $2.1B growth projection (FMI 2025)
