Adiprene LF Composite - XDC

1 Adiprene LF products are TDI-based prepolymers with exceptionally low levels of free TDI monomer. These products offer cast polyurethane processors important advantages in three areas: Hygiene All TDI based prepolymers contain unreacted TDI monomer. The level of monomer can vary from to by weight, with high hardness materials generally having the highest level of free TDI. Regardless of hardness, all Adiprene LF products have less than free TDI, which can be beneficial in the management and control of worker exposure to TDI. Processing Relative to conventional TDI based prepolymers of equal hardness, Adiprene LF products have the processing advantages of longer pot life and lower viscosity.

2 These qualities can improve the performance of a casting operation by reducing scrap while increasing the variety of products that may be made via the casting process. End-Use Performance A third advantage of Adiprene LF prepolymers is excellent end-use dynamic performance. This material has low heat build-up due to hysteresis in high speed, high load-bearing applications such as rolls, tires and wheels. Therefore, it may be possible to expand the use of polyurethane into more dynamically demanding applications.
