CAST ELASTOMERS

POLYURETHANE PREPOLYMERS
Prepolymer only - require curative component such as MBCA, DMTDA, DETDA, or polyol for casting applications, or a formulated B component for spray polyurea applications.

TDI
TDI systems possess dynamic properties and reliable processing characteristics.

TDI PTMEG in 72, 82, 90, 92, and 96 Shore A
TDI PTMEG/PPG ~50/50 blends in 82, 90, and 95 Shore A
TDI PPG & PPG/PTMEG-blends in 82, 86, 92 Shore A and 61 Shore D
TDI polycaprolactone polyester prepolymers
TDI polyester prepolymers
Custom TDI prepolymers

H12MDI
H12MDI prepolymers provide high hydrolytic stability, resistance to acids and bases, UV stability, and resistance to moisture degradation.

H12MDI PTMEG in 90 and 97 Shore A
Custom H12MDI prepolymers

MDI
MDI prepolymers / quasi-prepolymers provide high resilience, good adhesion, and with quasi-prepolymers - low viscosity.

MDI polyether and polyester prepolymers in 7-10% NCO
MDI PPG/PTMEG polyether quasi-prepolymers in 12-16% NCO
MDI PPG polyether quasi-prepolymers in 12-16% NCO
Custom MDI prepolymers

CUSTOM PREPOLYMERS
In addition to TDI and H12MDI, custom prepolymers are available using IPDI and TXMDI, with various polyether and polyester polyols. Quantities as small as 20 gallons can be produced.
