| VIBRATHANE 6012 is a polyester-based MDI-terminated prepolymer which yields 87A to 53D hardness urethanes when extended with 1,4-butanediol or hydroquinone bis (betahydroxyethyl) ether (HQEE) curatives. Urethanes from VIBRATHANE 6012 have these features: FDA approved for use with both wet and dry foods Outstanding abrasion resistance High tensile and tear strength Excellent load-bearing capability. No methylene bis (ortho-chloroaniline) (MBCA) required Lower isocyanate exposure Superior urethane hydrolytic stability&& |
