Product Description:
Prepolymers are reactive intermediates used in polymer manufacturing. They remain soluble and meltable, making them ideal for controlled processing. Polyurethanes can be produced through:
One-step method:
Direct reaction of a polyol with a polyisocyanate
Two-step method:
Formation of a prepolymer followed by chain extension to form the final polymer
Key Applications:
Prepolymers are used in the production of:
- Cast polyurethane components
- Rigid and semi-rigid foams
- Flexible polyurethane foams
Common Uses Across Industries:
Insulation:
Used in rigid polyurethane foams for thermal insulation in buildings, refrigerators, cold storage units, and refrigerated transport.
Construction:
Applied in insulated panels, pre-insulated pipes, and as a binder in engineered wood products like particleboard and fiberboard.
Refrigeration:
Essential for thermal insulation in household and commercial refrigeration systems.
Automotive:
Used in seating, dashboards, headliners, and as a binder for composite parts.
Coatings, Adhesives, Sealants, and Elastomers (CASE):
Ideal for coatings, adhesives, sealants, and elastomers, offering weather resistance, strength, and durability.
Footwear & Sports Equipment:
Used in the manufacturing of footwear soles, protective gear, and sporting goods.
Binders for waste foam / Rubber Recycling:
Prepolymer-based binders help convert waste foam and rubber into value-added products like orthopedic mattresses and rubber flooring tiles.
