|---|
| VIBRATHANE 8083 is a TDI-terminated polyester based prepolymer which yields an 85 Shore A hardness urethane when cured with 4,4′-methylene bis-(orthochloroaniline), commonly called MBCA. This prepolymer is liquid at room temperature, exhibits low viscosities at processing temperatures and is exceptionally heat stable. Vibrathane 8083 elastomers are characterized by: High tensile and tear strength. Excellent heat, fuel and solvent resistance. Outstanding abrasion resistance. Good low temperature and dynamic properties.&& |
