What is the real waterproof and breathable membrane


The waterproof and breathable membrane is produced by the middle layer of polyolefin microporous membrane and two layers of non-woven fabric through advanced thermal lamination process. Polyethylene resin is the main waterproof layer, and double-surface composite polypropylene filament non-woven fabric is used as the reinforcement layer. Composite molding by fusion direct compression process. So what does the real waterproof and breathable membrane look like? The following is introduced by the editor of Kunshan Yizhenpin waterproof and breathable membrane manufacturer:

The polyethylene film of the main waterproof layer is made of linear low-density polyethylene (LLDPE) resin with good puncture resistance. At the same time, auxiliary materials are added to improve the flexibility and adhesion of the main waterproof layer of the membrane. agent to improve the aging resistance of the main waterproofing layer of the membrane. Air permeability resin is added to improve its air permeability.

The surface reinforcement layer adopts new polypropylene filament hot-rolled spunbond non-woven fabric. The main functions are: first, to increase the overall tensile strength of the core layer (main waterproof layer), so that the thickness of the core layer is relatively reduced; The surface roughness makes the core layer play a protective role; the third is to provide a bondable network void structure.

The product is spread on the building roof or the insulation layer of the outer wall, and under the water strip, while strengthening the watertightness and airtightness of the building, at the same time, with its unique ventilation function, the moisture in the enclosure can be discharged smoothly, so as to effectively maintain The service life of the building has the functions of heat preservation, energy saving and improvement of the living environment.

The real waterproof and breathable membrane is suitable for curtain walls, profiled steel plates, steel-wood knot exterior walls and sloping roofs. It is highly breathable and adopts the latest domestic technology to overcome the shortcomings of most manufacturers in the past. Contains glue, so it can withstand temperature above 100 degrees, smooth surface, no wrinkling and foaming, good composite fastness, high strength and air permeability, high strength and anti-aging, this is the current domestic product that can really meet the EU standard.

Kunshan XinZhenpin Co., Ltd. is a professional manufacturer of waterproof and breathable membranes. It has been focusing on the research and development of waterproof membranes for 20 years. It provides waterproof and breathable membranes, waterproof double-sided adhesive tape, waterproof and breathable membranes for electronic appliances, waterproof membranes for mobile phones and other electronic and electrical die-cutting accessories.
