How to choose the waterproof and breathable membrane correctly?
The choice of waterproof and breathable membrane is related to the use direction, working temperature, installation size, ventilation requirements, protection requirements and other items. For details, please consult the company's sales staff.

What determines the air permeability of the waterproof breathable membrane?
The air flow rate is determined by the material of the waterproof and breathable membrane, the effective air flow area, and the pressure difference between the inside and outside.

Can the product size be customized?
Can be customized according to drawing requirements.

How can the waterproof and breathable membrane leak in the test?
 1. Test conditions exceed product performance.
 2. The time after the adhesive is pasted on the test product is too short, and the adhesive is not completely stable. It is recommended to test after 36 hours.
 3. Adhesive bonding is not reliable, the bonding surface of the workpiece is not cleaned, there is dust or oil stains, and there are pits, bumps, cracks, etc. on the bonding surface.
 4. The other parts of the workpiece are not well sealed. It is recommended to block the air holes first, first verify the air tightness of other parts, and then test the film after confirming that it is correct.
