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 A30, A50, A70, A90 Hardness

Components : Polyether Polyol Mixture and Polymeric MDI Isocyanate Mixture.

Applications : Various applications of a A-Scale Polyurethane Elastomer where easy processing (1:1 Volume Ratio, Low Viscosity) and good Physical Strength (Tensile, Tear, Abrasion) is required.

 

Advantages:

1:1 Volume Ratio (Iso/Poly)
Low viscosity
Long Open Time
Low Exotherm
Clear to translucent color
Material Cost
Room Temperature Cure
