一、            PTFE微孔薄膜简介Introduction to PTFE Microporous Membrane

PTFE微孔薄膜由高结晶度的PTFE分散料，经过挤压、纵向拉伸、横向拉伸，最终形成带有立体三维结构的薄膜。其孔径在0.02～5um之间，薄膜厚度在8～30um，孔隙率在80～97%之间。

PTFE micro-porous membrane is made up of high crystallinity PTFE fine powder and shaped into 3D structure through compressing, vertical and horizontal stretching. The membrane pore size is between 0.02~5μm, thickness is 8~30μm and porosity is between 80~97%.

 

 

金由iTEX高性能PTFE微孔薄膜特点

金由iTEX高性能PTFE微孔薄膜在生产之初，严格控制PTFE分散料品质。配合18年PTFE微孔薄膜的生产经验，在生产过程中，对于细节精益求精。加上多处“独到”的生产工艺，使金由iTEX高性能PTFE微孔薄膜具有高耐水压力、高透湿性、高机械强度等性能。

 

Features of Jinyou iTEX PTFE membrane

The PTFE fine powder is controlled strictly before to be used as approved material.  

And thanks to our 18-year experience and unique technology in producing PTFE membrane, we have consistently improved the product in every detail.

Therefore, iTex membrane is featured by high water resistance, high breathability and high durability.

 

 

高耐水压力：在20次水洗以后，按美国ASTM D751-2006标准测定：C型达20,000mm耐水压力。S型可达67,000mm耐水压力，已达美国MIL-DTL-31011B水平（美国军方标准），特别适用于军、警、消防官兵服装。

High Water Resistance

According to ASTMD7751-2006, water resistance for type C reaches 20,000mm H₂O and Type S reaches up to 67,000mm H₂O after 20 times washing, which meets the standard of US MIL-DTL-31011B. Therefore, it becomes ideal material to make uniforms for army, police and firefighting.

 

高透湿/透气性：洗涤前透湿量（汗液形成的水蒸气）按日本标准JISL099B1标准测试，C型达5000g/m²·24h以上,S型达7500g/m²·24h以上。

High breathability / Air Permeability

According to JISL099B1, the moisture breathability for Type C reaches over 5000g/m²·24h and Type S over 7500g/m²·24h before washing.

 

高耐用性：金由iTEX高性能PTFE微孔薄膜，由于在生产过程经过的特殊的处理，使其具有极好的防油污性能。即使多次洗涤剂水洗后，仍具有高耐水压优点。解决了目前中国国内市场上一般PTFE面料，经水洗后耐水压急剧下降的难题，使用寿命大大延长。

High Durability

Jinyou iTEX PTFE membrane has excellent oil and stain repellence due to special treatment. It also maintains high water resistance after being washed many times by detergent.

In contrast, water resistance from other companies’ membrane garment in Chinese market still drops dramatically after being washed.

So Jinyou iTEX PTFE membrane can greatly extend the service life and be a leader in the market.
