At Kunshan Xinzhenpin New Thin Film Material Technology Co LTD., we specialize in the research, development, and manufacturing of high-performance ePTFE (expanded polytetrafluoroethylene) waterproof and breathable membranes. Our advanced microporous membranes deliver exceptional protection against water, dust, and contaminants while allowing air and vapor to pass freely — ensuring reliable pressure equalization, moisture management, and long-term product durability across demanding applications.
Quality and sustainability are deeply embedded in our operations. We are proud to hold internationally recognized certifications, including GB/T 24001, ISO 14001, and IATF 16949, among others. GB/T 24001 and ISO 14001 validate our robust environmental management system and our continuous commitment to minimizing environmental impact throughout the production lifecycle. The IATF 16949 certification — the global benchmark for automotive quality management — demonstrates our ability to consistently meet the strictest requirements of the automotive supply chain, from product design and process control to continuous improvement and defect prevention.
Whether serving the automotive industry (lighting, ECUs, battery packs, sensors), outdoor electronics, industrial enclosures, or consumer devices, our ePTFE membranes are engineered to perform with unwavering consistency. Supported by state-of-the-art production lines, rigorous in-house testing, and a strong quality culture, we deliver tailored venting solutions that enhance product reliability and extend service life.
Beyond standard products, we excel in providing fully customized membrane solutions. Our engineering team works closely with customers from concept to production, optimizing membrane characteristics such as pore size, thickness, air flow, and water entry pressure to match precise application requirements. Every solution undergoes rigorous in-house testing — including IPX7/IPX8 water immersion, thermal shock, chemical resistance, and cyclic pressure tests — to ensure dependable field performance. With a customer-centric approach, we are committed to rapid sample delivery, flexible order volumes, and responsive after-sales support. Our membranes are trusted by leading brands in automotive, new energy, outdoor electronics, and medical device sectors, helping them achieve higher product reliability and full compliance with international standards.
