| Andur 7501 DPLF is a polyether (PPG) based liquid, toluene diisocyanate terminated prepolymer containing .1% or less free TDI. An elastomer with a hardness of 74 to 77 Shore D is obtained when this prepolymer is cured with Curene 442 [4,4'-methylene-bis (orthochloroaniline)]. Elastomers of lower hardness can be obtained by reaction with various polyols and their combination with Curene 442 and other diamines, or through the use of plasticizers. |
