Unsaturated Polyester Resins (UPR) are versatile thermosetting polymers synthesized from unsaturated dibasic acids and diols, dissolved in reactive monomers like styrene. Renowned for their excellent mechanical properties, chemical resistance, and cost-effectiveness, UPRs are widely used in composite manufacturing.
UPRs form the backbone of glass fiber-reinforced plastics (FRP), coatings, and castings, serving industries from marine engineering to aerospace.
The manufacturing of UPR involves precise steps to ensure optimal performance:
Parameter | Standard UPR |
---|---|
Appearance | Light yellow viscous liquid |
Viscosity (25 °C) | 350-620 mPa*s |
Density | 1.05-1.10 g/cm³ |
Acid Value | 14-25 mg KOH/g |
Solid Content | 57-68% |
Gel Time (25 °C) | 5-15 minutes |
Tensile Strength | 50-140 MPa |
Flexural Strength | 90-200 MPa |
Heat Deflection Temp | 47-135°C (1.82 MPa) |
Volume Shrinkage | 5-8% |
Certifications | ISO 9001, REACH, RoHS |
