Elastomer TSP

Product description:
ELASTOMER TSP is a polyester based urethane cast system with can be used for the production of a range of polyurethane elastomers from 55 – 95 Sh A hardness.

Fields of application:
PROCESSING The optimum processing temperature for Elastomer TSP series components is as follows: CHEMOLAN TSP1 prepolymer 40 - 50°C CHEMOLAN TSP3 curative 40 - 50°C CHEMOLAN TSP2 polyol 35 - 40°C The mixed components should be cast into pre-released moulds heated to a temperature of approximately 80°C. Gel Time 5 - 30 min at 90°C mould temperature Demould Time 30 - 80 min at 90°C mould temperature Heating Time 24 – 48 hours at 90°C

MIXING RATIOS

ELASTOMER TSP can be blended in the following proportions to give a range of hardness curatives.

Hardness [Sh A] 55 60 65 70 75 80 85 90 95
CHEMOLAN TSP2 (polyol) 360 207,7 160,3 142,5 126,7 107,6 86,8 70 53,2
CHEMOLAN TSP3 (curative) - 7,3 9,7 10,5 11,3 12,2 13,2 14 14,8
CHEMOLAN TSP1 (prepolymer) 132 118 115 113 112 110 108 107 105

The above ratios are in parts by weight and should be measured to an accuracy of ± 1%.
