As some products have higher and higher requirements for waterproof performance, many customers will use the characteristics of ptfe waterproof and breathable membrane to achieve waterproof requirements.
Let’s introduce it below.
Waterproof and breathable membrane (breathing paper) is a new type of polymer waterproof material.
In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. At the same time, from a quality perspective, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have.
It is a ptfe waterproof and breathable membrane manufacturer that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
The technology of ptfe waterproof and breathable membrane was first introduced from European and American countries. However, the production processes of domestic products are diverse, and the quality of products from various manufacturers is uneven, failing to form a unified quality standard.
In fact, waterproof and breathable membranes mainly consist of three layers: PP spunbond non-woven fabric, PE polymer breathable membrane, and PP spunbond non-woven fabric.
The main function of spunbond non-woven fabric is to enhance tensile force and hydrostatic pressure and protect the middle layer (breathable film). Real breathability mainly relies on the middle layer PE polymer breathable film.
Undertake various filter material coating processing services. Our company will perform coating processing according to the coating substrate provided by the customer or the coating substrate specified by the customer.
The key to its technology is the optimized combination of speed ratio, pressure ratio, operating temperature and other parameters. Our company can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different needs of users.
