BH adheres to the development direction of scientific and technological innovation, and strives to be an industrial pioneer. For polyester backing fabric, a part of reverse osmosis membrane, aiming to make pure water, is a wet-laid non-woven project, jointly developed by BH and some famous universities. The production of the above product fills its blank and achieves the transformation of our products.

Reverse osmosis membrane substrate (polyester wet-laid nonwovens), as the backing fabric of RO flat sheet, polyester nonwoven fabric provide the structural strength of the whole membrane. Polyester wet-laid nonwoven has uniform surface, high strength and excellent coating performance.
