Rim Elastomers with Improved Catalyst Efficiency |
| abstract |
A reaction injection molded polyurethane elastomer is made by reacting a polyisocyanate (the A- component) with a high molecular weight polyhydric polyether and a low molecular weight active hydrogen containing compound having a functionality of at least two (the B- component in the presence of a tin catalyst, wherein all of tin catalyst is mixed with the A-component before reaction. Reaction proceeds more quickly with the use of less catalyst than is needed with the conventional process in which the tin catalyst is incorporated in the B-component. Moreover the elastomer properties (tensile strength, tear strength, elongation, impact resistance and sag) are improved. |
