Abstract
A material suitable for fabrication into protective garments that is a laminate formed from a layer of a reflective metallic material to provide flash protection and a layer that inhibits penetration by toxic and corrosive chemicals to protect against chemical exposure; both adhered to a cloth substrate to provide support.
Claims10
A laminate material suitable for use as protective clothing comprising:
- a. a first layer of flame retardant heat sealable thermoplastic film;
- b. a second layer bonded to said first layer comprising a pliable cloth substrate;
- c. a third layer that is impermeable to toxic agents and bonded through a flame retardant thermoplastic film layer to said second layer;
- d. a fourth layer comprising a material reflective to radiant heat and bonded through a flame retardant thermoplastic film layer to said third layer;
- and
- e. a fifth layer of flame retardant, substantially radiant heat transparent and light transparent, heat sealable, thermoplastic film bonded to said fourth layer.
