High Performance Cold-Cure Elastomers for Industrial Castings
Cold-Cure Systems That Simplify Industrial Processing
UrePac® Cast elastomers are designed to be processed at ambient temperatures above 15°C — making them suitable for operations where conventional heated tooling or ovens are not practical.
With quick gel times and excellent demould properties, these systems are ideal for small or large component casting across a wide range of hardness levels, from 35 Shore A to 85 Shore D.
All systems are two- or three-component polyurethane formulations, developed for tooling, moulds, protective parts, electronics encapsulation, and rigid industrial castings.
2K, 3K, and BIO-Based Systems
Our UrePac® Cast Elastomer range includes versatile 2-component (2K), 3-component (3K), and BIO-based systems designed to meet a wide spectrum of performance and processing requirements. Whether you’re casting high-strength industrial parts, moulding complex shapes, or looking to reduce environmental impact, these systems deliver exceptional mechanical properties, chemical resistance, and processing flexibility.
2K Cast Elastomer Systems
Two-component systems: polyol + isocyanate
Preformulated hardness levels (e.g. 60A, 85A, 95A, 85D)
Processable at room temperature (>15°C)
Demould typically within 6–17 minutes
No post-curing required (optional: 75°C for 12–16 hours to enhance performance)
Ideal for fast prototyping, general-use parts, and cost-sensitive applications
3K Cast Elastomer Systems (Quasi MDI Technology)
