Poolkemie provides a large range of polyurethane rubbers, with different properties, according to the specific application. Available self-release and not-self-release formulations. The ones with no anti-adherence features need a release agents treatment before application.
The polyurethane rubbers are polyurethane elastomers curing at room temperature. Are characterized by high fluidity (applicable by pouring), high mechanical strength and no linear shrinkage. Therefore they can assure absolute faithfulness in the reproduction of smallest details.
Owing to their high chemical-mechanical properties combined with high elasticity, the polyurethane rubbers are suitable for making flexible moulds and matrices to reproduce, starting from an original model, objects in different applicative sectors.

Materials that can be used in hand-made objects reproduction from polyurethane rubbers matrices are: natural and synthetic waxes, plaste, cement and ceramic pastes.

- No linear shrinkage
- High elasticity, easy demoulding also for objects with undercuts
- Extreme faithfulness in the reproduction of details from any original model
- Easy mould building, no need of particular equipments
- Adding appropriate charges the elastomer can be worked with tools
- Some polyurethane elastomers have anti-adherent properties
- Some polyurethane elastomers are not toxic (ex. TR series TDI monomer less than 0,1 %)
- Odourless.
