Urethane elastomers have various advantages when compared with rubber, plastic and metal. This is especially true in regard to the urethane elastomers made using our product Tolidine diisocyanate (TODI). TODI-based elastomers offer excellent heat and hydrolysis resistance, along with superior mechanical properties.
Concerning the manufacturing point of view, due to its longer pot life, TODI-based prepolymer is easier to handle in comparison to NDI-based products.
