Our company is absorbed in producing rubber water stop series and research and development. We could produce various rubber water stop series. And our products all have high quality. Rubber water stop use high elasticity to make elastic deformation under load. Thereby, it could make seal sturdy, and prevent structure leak and seepage in order to shock absorption.
