Orthophthalic Polyester Resin
Description: A general-purpose polyester resin with good mechanical and chemical resistance properties.
Applications:
Boat hulls and other marine applications
Automotive parts and components
Construction materials (e.g., panels, laminates)
General-purpose FRP (fiber-reinforced plastic) applications
Isophthalic Polyester Resin
Description: Offers improved mechanical strength, flexibility, and resistance to water and chemicals compared to Orthophthalic resins.
Applications:
High-performance marine applications (e.g., boat decks)
Chemical storage tanks and pipelines
Swimming pools
Corrosion-resistant industrial components
Dicyclopentadiene (DCPD) Modified Polyester Resin
Description: A modified resin with low shrinkage and high heat resistance, known for improved impact resistance and dimensional stability.
Applications:
Automotive panels and structural parts
Large-scale castings (e.g., manhole covers)
Electrical components (e.g., housings)
Bisphenol-A Fumarate Polyester Resin
Description: Contains bisphenol-A, which improves its chemical resistance, especially against acids and alkalis, and enhances thermal stability.
Applications:
Chemical storage and handling equipment
Tank linings for aggressive chemical storage
Piping and other components in the chemical processing industry
Vinyl Ester Polyester Resin
Description: Although technically a different class, vinyl esters are often combined with polyester for increased toughness, flexibility, and chemical resistance.
Applications:
Chemical-resistant linings and coatings
Offshore and marine applications
High-stress FRP components
Wind turbine blades and other renewable energy components
Hydroxyl-Terminated Polyester Resin
Description: Has hydroxyl groups, making it compatible with isocyanates in polyurethane formulations. It is used where flexibility and durability are important.
Applications:
Coatings, adhesives, and sealants
Polyurethane elastomers
Flexible coatings for wood, metal, and plastic
Carboxyl-Terminated Polyester Resin
Description: Contains carboxyl groups and is typically used in powder coating formulations. Provides strong, chemically resistant finishes.
Applications:
Powder coatings for appliances, automotive parts, and metal furniture
Adhesives and sealants
Structural composite materials
These thermoset polyesters, tailored through specific chemistries, serve industries requiring robust, durable, and specialized materials for high-performance applications.
