Pyrovatex Fire Retardant Orange Coverall
Suitable for Protection in Oil & Gas, Petrochemical and other related sectors.
Pyrovatex treated fabric offer very good protection against heat & flame. This fabric is durable to multiply washes and certified as per ISO11612 from BTTG (UK), STFI (Germany). Pyrovatex treated fabric also come in combination with anti-static grids, hi-visibility colours and OWR finishes. Chemical relellent finish option is also available in combination with FR for protection against select hazardous chemicals. With the cotton textile quality, we ensure the final products is soft touch with rich feel.
Pyrovatex has a life cycle of 70 washes. If proper care is taken the garment can last for 100 washes if no chlorine and other washing elements are used. It has the flame retardancy to withstand a 3 or 4 seconds flash fire and will protect against 1 and 2 degree burns.
Difference between Pyrovatex and Nomex
Pyrovatex are generally the least expensive types of flame resistant materials. The cotton fibers absorb and retain fire retardant chemicals in the treatment process. In general, they will retain the fire retardant properties beyond the point when the fabric is worn out. Because it is a cotton base, the material has excellent breathability, does not cause itching or irritation and is reasonably durable. It is also very stable in direct contact with flame, with no tendency to melt or shrink. These materials are common in a SFI 3.2A/1 rating but can be combined with other materials to achieve a higher rating.
Nomex®, which is a fire-retardant version of Nylon, developed by DuPont®. Nomex III® is a combination of Nomex® fibers and Kevlar® fibers. This combination is very stable in heat and flame and is very durable. It tends to have a higher TPP for its weight than the cotton materials. Cost of Nomex® varies widely, but is always considerably higher than cotton materials. Suit liners may consist of a layer of Nomex® knit material. The combination of an outer layer of Nomex® and a liner of Nomex® knit offers a lighter suit that still achieves an SFI 3.2A/5 rating.
Pyrovatex® started out as regular cotton material that has been treated with a fire retardant chemical. Nomex®, on the other hand is inherently in itself fire retardant and not dependent upon chemical treatment.
