This invention relates to the use of a barrier film, being a thermoplastic linear polyolefin resin, to protect a styrenic resin sheet which constitutes the inner liner wall of an insulative cabinet wall of, for example, a refrigeration appliance unit from attack by the halogen-containing blowing agents present in the insulative polyurethane foam found within the cabinet wall. Preferred thermoplastic linear polyolefin resins are linear low density polyethylene.

Pencil writable and printable synthetic paper comprising a finely porous polyolefin film layer having an opacity of at least 80% obtained by stretching a polyolefin film containing from 8 to 65% by weight of an inorganic fine powder having on one or both sides thereof a stretched ethylene-vinyl alcohol copolymer film layer, at least one of the stretched ethylene-vinyl alcohol copolymer film layers having a coat layer thereon. When printed, the stretched ethylene-vinyl alcohol copolymer film laye...

A polytetrafluoroethylene porous film, which is prepared by stretching a semisintered polytetrafluoroethylene material and heating the stretched material at a temperature higher than the melting point of sintered polytetrafluoroethylene, has an area ratio of fibrils to nodes of from 99:1 to 75:25, an average fibril diameter of from 0.05 to 0.2 .mu.m, a largest node area of not larger than 2 .mu.m.sup.2 and an average pore size of from 0.2 to 0.5 .mu.m and achieves low pressure loss.

A masking sheet comprising a corrosion-resistant film and, formed thereon, a layer of an adhesive comprising at least one of a chloroprene rubber, a nitrile rubber, and a styrene-butadiene rubber.

A laminate comprising a polyolefin film having a hardened coating adhered to one surface thereof. The coating is abrasion resistant and is the photopolymerization reaction product of starting materials comprising hydantoin hexacrylate and a fluorinated surfactant. The laminate finds particularly useful application as a component of energy control window films. An abrasion resistant coating composition is also disclosed.

A unique system to insulate and retain the cold temperature of products, liquids, or materials of any type or nature. In the preferred embodiment, the system comprises a series of layers of material as follows: (1) a hard, durable plastic layer of polyvinyl chloride or similar material; (2) a layer of retardant aluminum; (3) a layer of styrofoam; (4) a layer of neoprene; (5) a cavity which is filled with dry ice through an input valve at the top of the system and which is purged through an escap...

Wrapping material formed of a foamed plastic-like material. The wrapping is formed in elongated strips and adheres to itself and most surfaces it is applied to without requiring the use of a separate adhesive.

A structural laminate comprises at least one planar facing sheet comprised largely of glass fibers but not having micro-glass as a filler. The facing sheet is self adhered to a rigid thermosetting plastic foam core. The non-glass filler material is chosen from a group consisting of clay, mica, talc, limestone (calcium carbonate), gypsum (calcium sulfate), aluminum trihydrate (ATH), antimony oxide, cellulose fibers, and plastic polymer fibers. The non-glass filler material improves containment of...

This invention relates to a replaceable ink pad that is capable of supplying ink in excess of 5,000 printing cycles. The ink pad is made of a first layer of polyethylene foam that is attached to a bottom layer of felted melamine foam by a porous polyamide adhesive. The first layer has a pore size of 10-20 microns and the bottom layer has a pore size of 140-180 microns. A tray can be provided to securely hold the pad.

The present invention relates to novel coating compositions for use on preformed foam products, comprising an aqueous admixture of a PVC copolymer dispersion and a polyurethane dispersion together with suitable additives as wetting agents, pigments dispersants, fillers and the like. The coating compositions may be applied by dipping, spraying, or any other suitable application means well known to those skilled in the art.
