Resins for Thermosetting Urethane Elastomers

DIC possess a broad range of products based on our synthesizing techniques for polyester polyols, one of our core technologies.

Products can be designed according to application, from low hardness to high hardness.
Excellent abrasion resistance, solvent resistance, heat resistance, and load bearing.
Two curing system proposals are possible.
- Two-component curing by a prepolymer and curing agent (amine, glycol) (prepolymer system)
- Two-component curing by polyol and polyisocyanate (one-shot system)

Product Examples

As industrial components, they undergo a cutting process and are used in various applications.

We are promoting expansion into applications focused on cleaning blades and rolls for office equipment.

This table introduces typical product numbers. DIC will also propose product designs that meet your desired application by conditions.
