| Abstract: | The influences of the propolymer , stuffing , and silane on the mechanical properties of the polyurethane sealant such as francture strength .stretcher strain at the breaking point ,and hardness,are studied . It is observed that different prepolymers and stuffings have different influences on the properties of the sealant ,and carbon biack ,as a stuffing ,exhibits strong enhancement action. |
