Introduction
Polyester resins are versatile, thermosetting polymers renowned for their adaptability, cost-efficiency, and performance across a range of industrial and commercial applications. At Chem Horizon, our portfolio of polyester resins empowers manufacturers worldwide with tailored solutions for markets including paints and coatings, composites, construction, automotive, marine, and more.
What is Polyester Resin?
Polyester resins are complex polymers formed by the reaction of polyhydric alcohols and dibasic organic acids. Most commonly available as “unsaturated polyester resins” (UPRs), they are supplied in a liquid state and cured through crosslinking agents, often using styrene monomers and catalysts like methyl ethyl ketone peroxide (MEKP). Once cured, these resins deliver robust, durable, and chemically resistant structures.
Key Features
- Thermosetting: Forms a permanent, infusible matrix after curing.
- Adaptable Chemistry: Customizable for flexibility, hardness, chemical resistance, or rapid curing.
- Excellent Compatibility: Blends well with glass fibers, minerals, pigments, and fillers.
- Value-Driven: Provides a cost-effective alternative to epoxies and other high-performance resins.
Types of Polyester Resins
| Resin Type | Description/Features | Typical Applications |
|---|---|---|
| Orthophthalic | General-purpose, balanced properties | Boat hulls, tanks, pipes |
| Isophthalic | Enhanced chemical/stress resistance | Automotive parts, chemical tanks |
| DCPD Modified | Fast wet-out, lower viscosity, lower cost | Large composite structures |
| Low-Styrene Emission | Eco-friendly, reduced VOC | Conforming to environmental norms |
Chem Horizon supplies all mainstream and specialty grades to fit your precise manufacturing needs.
Technical Benefits of Polyester Resin
