There are many kinds of ptfe waterproof and breathable membranes

Waterproof and breathable materials, also known as breathable materials, refer to a material that can prevent liquid water from passing or penetrating, while at the same time allowing gas or water vapor to pass through.

There are many kinds of this material on the market, and ptfe waterproof and breathable membrane is one of them.

The air tightness, water tightness and vapor permeability of the envelope system are crucial to the energy saving, durability and comfort of the building.

European and American countries developed waterproof and breathable membranes in the late 1980s and were vigorously promoted. Waterproof and breathable membrane enclosure systems are widely used in civil and commercial buildings. Building structures using waterproof and breathable membranes are known as “breathable membranes”. House of”.

In recent years, the Chinese government has paid more and more attention to building energy conservation. With the continuous improvement of energy conservation and environmental protection requirements, waterproof and breathable membrane enclosure systems have gradually been valued by the industry.

PTFE waterproof and breathable membrane is made through special processes such as mixing, extrusion, extrusion, calendering, and biaxial stretching.

Due to the characteristics of ptfe fibrillation, when performing unidirectional stretching (i.e. longitudinal stretching), the ptfe polycrystalline aggregates begin to extend and form some fibrils. The fibrils are parallel to the stretching direction. At the same time, the fibrils The length increases.

The cross-section of ptfe fibrils is wide and thin, its maximum width is about 100nm, and the smallest fibril is ?0.5??1.0nm.

The manufacturer has advanced ptfe waterproof and breathable film production lines, lamination and composite production lines, which are at the domestic advanced level.

With strong technical force, strict management system, brand-new production equipment, and complete testing instruments, we ensure that everything is focused on the interests of users and provide users with high-tech, high-quality, high-performance, and high-level products.
