Abstract:

The present invention provides an adhesive composition for use in bonding a polymeric fitting to an olefin-containing component of an article used in medical applications. The adhesive composition according to the invention includes an adhesive polymer system dissolved in a solvent system. The solvent system includes an organic solvent having a solubility parameter within the range of from about 7. 5 to about 10 (cal/cm ). Subsequent to forming a bond between the polymeric fitting and the olefin-containing component, the adhesive composition can meet the requirements for USP Class VI materials. In a preferred embodiment of the invention, the adhesive composition includes a low shear mixture of an adhesive polymer system including an atactic polypropylene and a low density polyethylene that is dissolved in a solvent system including a blend of d-limonene and a ketone selected from the group consisting of 4-heptanone and cyclohexanone. The adhesive composition can be used, for example, to bond polymeric fittings made of materials such as, but not limited to, acrylic, polycarbonate, polyvinyl chloride, polyolefin, acrylonitrile butadiene-styrene, and polyester, to olefin-containing components of articles used in medical applications such as, but not limited to, tubing.

International Classification:

B32B 2708
US Classification:

428517
Abstract:

A compatibilized polymer alloy has been developed which has excellent processability under thermoforming conditions and the molded articles produced from the alloy exhibit superior gloss, shrinkage, surface hardness, polarity, strength and high heat distortion. The alloy is, in general, comprised of a polyolefin composition, a polystyrene copolymer, or polymer blend, and a compatibilizing agent. This polymer composition or alloy is particularly useful in producing packaging materials and food containers.

International Classification:

B32B 2708
C08L 5302
US Classification:

428330
Abstract:

This invention relates to a multilayer thermoformable structure comprising (A) at least one cap layer and (B) at least one core layer, and polymer compositions for making the same. The multilayer structures and polymer compositions of the invention are useful in preparing thermoformed articles and are particularly useful in preparing liners for refrigerators and freezers. The multilayer structures and the polymer composition have good thermoformability and chemical resistance. The multilayer structures and the polymer composition have good surface properties including a glossy finish. Further these materials are compatible with new blowing agents, such as the hydrochlorofluorocarbons and hydrofluorocarbon blowing agents, which are more environmentally friendly. The layers of the multilayer structure do not require a glue layer.
