A fire-retardant laminated plastic material which includes a woven barrier layer of high-density polyethylene sandwiched between outer layers of low-density polyethylene material in which a polymer of antimony trioxide is incorporated in the outer layers. Additional outer layers may be laminated to the structure to serve as a carrier of pigments or to increase abrasion resistance of the structure.
The invention provides a film composition comprising a thermoplastic polymer having a melt flow rate of 20 to 2000 (g/10 min), and a flame-retardant, and a self-extinguishing laminated film comprising at least two thermoplastic polymer films, at least one of the thermoplastic polymer films being a meltable film prepared from the composition.
Fire-retardant barriers are described which are useful for protecting military personnel and equipment from both fire and chemical and/or biological agents. The fire-retardant barriers are multilayered structures having desirable flammability characteristics and resistance to chemical and/or biological agents. The preferred barriers also possess favorable durability properties and are printable.
A coextruded film with both gas barrier and fire retardant properties as well as good physical properties is made up by melt coextrusion to form a four or five layer film product useful in making laminates for protective clothing or tarps. The five layer film has a Saran resin barrier core layer and LDPE skin layers on each face with intervening EVA glue layers. The four layer film has a Saran resin barrier core layer and a CPE skin layer on one face and an EVA skin layer on the other with an EVA glue layer between the barrier core layer and the CPE skin layer. Each skin layer and each glue layer contains about 8 to about 30 percent by weight of a polyhalogenated organic/antimony oxide fire retardant and a small amount of a slip agent.
The invention provides a sheet material which comprises a non-woven plastics film and bonded thereto without an adhesive, a barrier film; the sheet material is especially useful for the production of ostomy bags.
