TODI

Introduction

Urethane elastomers have various advantages when compared with rubber, plastic and metal. This is especially true of the urethane elastomers made using Tolidine diisocyanate (TODI). TODI-based elastomers offer excellent heat resistance and hydrolysis resistance properties along with superior mechanical properties.

From the manufacturing stand point, TODI-based prepolymer can be stored for certain period, and TODI, because of its longer pot life, is easier to handle than NDI-based products.
