TDI 83A is a hot curing TDI-based liquid PTMEG prepolymer

TDI 83A has exceptional abrasion and tear resistance, resistance to oils, solvents, hydrocarbons, weak acids and alkaline environments, and temperature extremes.

It is used for the production of engineering parts, sheets, rods, rollers, bushings, rings and gaskets, some auto parts and devices for car tires, as well as for lining.

Material can be processed both by machine and manually. Produced in the EU by OSV Technology order.
