​What happens to the waterproof and breathable membrane when it encounters water?


Many customers will have some questions when they buy waterproof and breathable membranes. Is the waterproof and breathable membrane they bought really waterproof when exposed to water?

There is the worry of coming off. Today, I would like to share with you how the waterproof and breathable membrane meets water:

The technology of waterproof and breathable membrane was first introduced from European and American countries. However, the production process of domestic products is varied, and the quality of products of various manufacturers is uneven, and a unified quality standard has not been formed.

In fact, the waterproof and breathable membrane mainly consists of three layers: PP spunbonded non-woven fabric, PE polymer breathable membrane, and PP spunbonded non-woven fabric. The function of spunbonded non-woven fabric is mainly to enhance the tensile force and hydrostatic pressure and protect the middle layer (breathable film). The real breathability mainly depends on the middle layer PE polymer breathable film.

This material has the characteristics of acid and alkali resistance, resistance to various solvents, and also has the characteristics of high temperature resistance, at least 250 degrees.

It is very inert to most chemicals and solvents, and is also resistant to water and various organic solvents.

It is also the best aging life among plastics.

Lowest coefficient of friction among solid materials.

Surface tension is minimal and does not stick to any substance.

The characteristics of the above points can fully represent that as long as the quality and production of the waterproof and breathable membrane are no problem, the product will definitely be waterproof and there will be no risk of falling off.

Kunshan Xin Zhenpin is a professional manufacturer of waterproof and breathable membranes. It has been focusing on the research and development of waterproof membranes for a long time. It provides a variety of product choices such as waterproof and breathable membranes, waterproof and breathable membranes for electronic appliances, waterproof membranes for mobile phones, waterproof and breathable membranes for small appliances, and waterproof and breathable membranes for packaging.
