New arc-rated GORE-TEX PYRAD® Stretch Garments

Following years of intensive research and development, this latest offering from the GORE-TEX Brand will revolutionise the PPE market because it is an intelligent combination of Gore’s proprietary technologies with different engineering techniques and PYRAD® product technology. The result: arc-rated Class 2 foul weather protection which is extremely comfortable and easy to wear, whilst being incredibly lightweight.

What makes GORE-TEX PYRAD® stretch technology different?

Typically, the arc-rated hardshell rainwear solutions currently available to protect electrical engineers restrict freedom of movement and can be heavy, bulky and absorb water. 

Stretch: Gore’s new fabric technology has a unique stretch attribute, in fact, it has 50% more stretch than other existing products available.

This means workers can easily bend, kneel, climb and stretch during active work because garments are noticeably softer and far more comfortable to wear.  Unlike other fabrics serving to protect workers against the risk of an accidental arc, GORE-TEX PYRAD® stretch garments are remarkably quieter when worn due to the suppleness of the fabric.

Lightweight: The fabric consists of 2-layers in combination with a flame-resistant liner, an outer shell fabric and an advanced elastic ePTFE membrane, coupled with the protective GORE-TEX PYRAD® fabric technology. Jackets and trousers constructed utilising this fabric technology are 45% lighter than other Class 2 arc protection rainwear available. 

Weatherproof and breathable: Arc Rated GORE-TEX PYRAD® stretch garments will durably protect the wearer against foul weather. They block out wind, even in the stormiest conditions, which eliminates any wind chill factor and helps to maintain a comfortable wearing temperature.  Additional wearer comfort is also achieved because jackets and trousers engineered with GORE-TEX PYRAD® stretch technology delivers a 25% increase in breathability. This helps to prevent a buildup of moisture on the inside of the garments. As well as being weatherproof, the fabric is resistant to common hazardous liquids.

The science behind GORE-TEX PYRAD® fabric technology

During an arc flash exposure, countless reactive dots rapidly react to the heat even before the outer shell starts to burn. The reaction of the dots causes them to expand by a magnitude of more than 10x higher than its original size and form a stable insulating protective shell of carbonaceous char with the face fabric without melting or dripping.  This stops flame propagation, blocks convective and radiant heat from the arc flash exposure, and reduces the heat transfer to the wearer’s skin. In addition, the physical integrity of the laminate is maintained after heat and flame exposure, which means no break or hole formation.

Jonas Andersson, Sales Associate in WL Gore & Associates’ Fabrics Division comments: “We are delighted to be bringing new arc-rated GORE-TEX PYRAD® Stretch Garments to the UK market.  Several of our licenced manufacturing brand partners will be launching these garments from the summer onwards. We believe that the total protection and wearer comfort from these garments will be well received and are much needed within the electrical engineering sector.”
