825 - Microrip

When firemen choose a PTFE membrane because of its breathability and its flame resistance, we usually propose complex 825. This assembly makes use of our SIO-A.I.R. PTFE membrane. Our ePTFE membrane is laminated on a non-woven 3D aramid fabric that plays an important role in the thermal protection. 

This membrane has received the Sio-Comfort quality label that identifies breathable and flame resistant barriers. 

Complex composition

  1. Outer fabric: Nomex® Microrip Sioguard

    98% aramid - 2% AST - 230g/m2

    Our Nomex® Microrip Sioguard is an outer fabric that was designed to provide an optimal protection for firemen during their different missions. It is developped and produced in France according to a strict protocol and is also in conformity with the ÖEKO-TEX® standart 100 standard which confirms that the product doesn't contain any harmful substances that pose a threat to human health. 

    Its mechanical characteristics are 3 times better than the demands of the standard EN 469. The original weaving of the material offers an excellent breathability and a high abrasion resistance. The garment that is manufacterd with DuPont™ Nomex® has during its entire life an excellent light and wash fastness.  

    The Microrip Sioguard protects today several thousands of fireman throughout Europe. Its reliability doesn't need to be proved anymore and its breahtability offers an excellent comfort. Thanks to the Sioguard treatment against chemical substances it hasn't to be reimpregnated which simplifies the maintenace and reduces costs. 

    The Microrip Sioguard is available in different colours: navy, yellow, orange and red.

  2. Waterproof membrane: SIO-A.I.R. PTFE

    100% aramid

    In their risk analysis firemen sometimes demand that the membrane is not only breathable but also very heat resistant. That's why we developped our own solution the SIO-A.I.R barrier PTFE. We have laminated a base layer of PTFE on a 3D felt of 100% aramid.

    The SIO-A.I.R barrier PTFE is tested in accordance with the ISO 6530 standard (Protection against liquid chemicals - Test method for resistance of materials to penetration by liquids). It is waterproof, with a water column of more than 10 metres, even after it has been exposed for 7 seconds to a temperature of 220°C. It also passes the kerosene test. 

    Finally the membrane also passes after 25 washes at 60°C the ASTM F1671 test which prooves that a selection of virsuses can't penetrate the SIO-A.I.R barrier PTFE membrane.

    This membrane has received the SIO-Comfort® quality label which identifies breathable, flame resistant barriers.

  3. Thermal barrier: Quilted felt on technical 3D Nomex® fabric

    100% Nomex®

    The Nomex® felts are known for their excellent insulating qualtities when they are used in protective textile.  

    The use of a felt layer guarantees a good thermal insulation. Moreover, we quilt the felt with our technical 3D Nomex® fabric which improves the mechanical and thermal qualities of the garment. 

    The lining of a jacket is often considered to be the poor relation of the complex. We, on the other hand, think that it is every bit as important as the other layers. It is in direct contact with the skin and has to bear a lot of mechanical stress. The lining can't retain moisture and plays an important role in the protection of the jacket. That's why we created this technical 3D fabric which has a very airy structure thanks to a specific weaving technique. This technical lining is composed of 95% Nomex® to be fire resistant and of 5% Kevlar® to have a good mechanical resistance.
