Tadco AM Series Tadco D Series Tadco E Series Tadco L Series Tadco M Series Tadco S Series Tadco X Series Tadco 11A Series Tadco 11B Series Tadco Roto-Systems
 

Two Component Polyurethane Cast Elastomer Systems 

Shore A50 - A97 Hardness

Components : Polyether Polyol Mixture and Polyether or Polyester / MDI Quasi-Prepolymer Isocyanate.

Applications : Any dynamic application where extremely high Tensile and Tear properties are not a necessity, but where low hysteresis (heat build-up), good compression and/or low cost is required.

Shock absorbers, Bushings, rollers, caster wheels, toys,…

Advantages
