We offer a complete range of polyurethane prepolymers for the cast elastomer industry. The chemical backbones we offer include isocyanates such as TDI and MDI, and polyol backbones such as PTMEG and PPG ethers, traditional ESTERS, and higher performance ester types such as CAPROLACTONES.
Each and every product is made to a strict quality standard, ensuring we offer you truly world class products.
Within each range there are numerous hardnesses available (Shore A to Shore D rating), as well as varying pot lifes (gel times and working life).
Our TDI and MDI products can be reacted with different types of curatives, some of which are listed in the separate category on the left, whereas our BINDERS and ADHESIVES are more commonly single component moisture reaction products.
If you are not sure which type of elastomer is ideal for your process, please contact us for further information.
