Porelle? Advanced film technology with functional outdoor apparel is a registered product of Porvair International. The company is a global high-performance specialty film manufacturer with over 25 years of specific market experience. It has strong scientific research and development. Its unique polyurethane polymer technology modulates the film for specific requirements. The product has passed ISO9002 certification and is the world's most Unique film manufacturer.
The porelle® film system is designed and manufactured to meet the requirements of extreme high performance outdoor apparel, making it extremely waterproof, breathable and durable. These films are currently used in many apparel application areas where the cost performance is relatively high. It is used by many military agencies in the world and has been widely used in medical, industrial R&D, sports and leisure and other fields.
The porelleTM product line features hydrophilic and microporous technology features that make its thin film products with a variety of technical properties, including
l Extremely high perturbation
l no noise
l Excellent feel and drape
l hydrolysis resistance
l High durability and scratch resistance
l Extremely high air permeability - standard RET values ​​from 0.4 to 10.2 depending on thickness
l waterproof, at least 7 meters upward, hydrostatic head
l Windproof
l Against viruses and blood thawing pathogens
l Flame Retardant Standards up to NFPA (National Fire Protection Association) specifications Film composite technology has proven to be the most practical and durable way to make high-performance waterproof breathable fabrics. Porelle® film composite fabrics provide long-lasting water resistance and extremely high breathability. And greatly beyond the performance of coated fabrics, uniform surface provides continuous protection.

Microporous films have non-hydrophilic character and can block water passage even at high pressures, but can drive water vapor through non-hydrophilic micropores due to the relatively high temperature inside the garment and the greater water vapor density.
Microporous film
Hydrophilic film
The structure is strong, breathable and completely waterproof.
At relatively high temperatures and water vapor densities, water vapor molecules can be driven from one hydrophilic layer to another to pass through the hydrophilic film.
