A multi-layer assembly for fluid and vapor handling and containment systems. The multi-layer tubing assembly comprises a permeation resistance layer of polymeric material and a layer of multiphase polymer surrounding the permeation resistance layer.

Multi-layer assembly for fluid and vapor handling and containment systems

A multi-layer assembly for fluid and vapor handling and containment systems. The multi-layer assembly comprises an extrudable inner layer of a polymeric material, a first layer of multiphase polymer surrounding the inner layer, a permeation resistance layer of polymeric material surrounding the first layer of multiphase polymer and a second layer of multiphase polymer surrounding the permeation resistance layer.

This invention relates to a multi-layer tubing assembly for use in fuel-line application. The multi-layer tubing assembly comprises an extruded inner layer of thermoplastic, an adhesive layer coextruded around the inner layer and a cover layer of a multiphase polymer coextruded around the adhesive layer. The multiphase polymer forming the cover layer comprises 0.5% to 20% by weight compatibilizers and rheology modifiers.

Multi-layer tubing assembly for fluid and vapor handling systems

A multi-layer assembly for fluid and vapor handling and containment systems. The multi-layer tubing assembly comprises an extrudable layer of conductive fluoropolymer, a layer of modified fluoropolymer containing a reactive group extruded around the layer of conductive fluoropolymer and a layer of polar polymer extruded around the layer of modified fluoropolymer. The layer of modified fluoropolymer is bonded to the layer of polar polymer.

A multi-layer tubing for use in fluid transport applications. The tubing is suitable for conveying fluids containing hydrocarbons. The tubing comprising an extrudable adhesive layer coextruded around a permeation-resistant layer of fluoropolymer and a layer of polymer chemically dissimilar from fluoropolymer coextruded around the adhesive . The adhesive layer is formed of a polymer blend or alloy having a multi-phase morphology wherein one phase is miscible with the fluoropolymer for forming the inner permeation-resistant layer and another phase is miscible with the polymer chemically dissimilar from fluoropolymer. To achieve sufficient bonding, the adhesive layer comprises at least 25% volume fraction of the first phase which is miscible with the fluoropolymer for forming inner permeation-resistant layer and at least 25% volume fraction of the second phase which is miscible with the polymer chemically dissimilar from fluoropolymer. Furthermore, the adhesive layer of polymer blends or alloys having a multi-phase morphology can be modified by adding compatibilizers and rheology modifiers to improve adhesion strength and to allow the material for forming the adhesive layer to obtain proper viscosity and elasticity for extrusion.

Composition for cleansing body with high foaming action

A stable shaving cream gel having superior foaming and after-feel characteristics containing as the essential ingredient a water soluble gel which is the interpolymer reaction product of a quaternized cationic polymer selected from the group consisting of poly(diallyldimethylammonium chloride-co-acrylamide) and a quaternary ammonium cellulose ether polymer, with an anionic polymer selected from the group consisting of a polysulfonic acid and alginic acid.

Shaving cream gel containing interpolymer reaction product of selected

The formation of novel water soluble and water insoluble gels by interpolymer reactions of selective anionic polymers with selective cationic polymers in an aqueous medium, with either polymer serving as a cross-linking agent under specific conditions of speed and concentration. The selective cationic polymer is a quaternized ammonium polyelectrolyte selected from the group consisting of poly (diallyldimethylammonium chloride), poly (diallyldimethylammonium chloride-co-acrylamide), and a quaternary ammonium cellulose ether polymer. The anionic polymer is selected from the group consisting of a polysulfonic acid and alginic acid. The formation of the gel structure depends on fast and intensive interaction of the two opposite charges to insure a maximum amount of ion pair formation. The solubility of the gel depends on the formation of intimate or loose ion pairs; which depends on the charge density and structure of the polyelectrolytes. These interpolymer gels exhibit a dramatic increase in viscosity. The water soluble gels produced can be used as foam enhancers and conditioning agents in cosmetic compositions such as shaving gels, shampoos and the like; and in sewage treatment (removal of sebum and traces of organic substances). The water insoluble gels are clear and of extremely high viscoelasticity which can be made into clear films.
