LUPRANATE T80
LUPRANATE T80
LUPRANATE® T80 toluene diisocyanate (TDI) is an 80% – 20% mixture of the 2,4 and 2,6 isomers of toluene diisocyanate. This product is used in the preparation of polyurethane foams, prepolymers and elastomers.
LUPRANTE T80 is available in two types:
- T80 Type 1 is the industry standard for high quality molded and slabstock foams.
- T80 Type 2 is acidified, often used for specialty prepolymer synthesis and CASE applications.
