Unsaturated Polyester Resin – DCPD Base
DCPD (Dicyclopentadiene)-based unsaturated polyester resins are a cost-effective class of thermosetting resins widely used in composite manufacturing. They are synthesized by reacting DCPD with glycols and unsaturated acids.
Key Properties
- Low Viscosity: Easier processing and better filler compatibility.
- Fast Curing: Suitable for high-speed production methods like SMC/BMC.
- Good Surface Finish: Ideal for aesthetic applications.
- Moderate Mechanical Strength: Suitable for non-structural components.
- Cost-Effective: Lower raw material cost compared to orthophthalic or isophthalic resins.
Applications
- Automotive parts (e.g., body panels, bumpers)
- Electrical enclosures
- Sanitary ware
- Decorative laminates
- General-purpose molded components
