A composite layered plastic article particularly resistant to outdoor exposure to heat, sunlight and UV degradation comprises a top surface exposed layer of PETG fused to a rigid substrate layer selected from PVC, or CPVC, or HIPS, or ABS, or ASA, or PC. The PETG layer is preferably co-extruded with the substrate layer and heat fused together to produce a laminated layered composite article. The composite layered plastic is particularly useful for color retention of dark colors and bright masstone colors, as well as pastel and white colors

Weather resistant plastic composites capped with polyethylene terephthalate glycol (PETG) for outdoor exposures

Compositions, composite articles and process for producing same are provided from a reinforced polyvinyl halide composition (A) comprising a high molecular weight polyvinyl halide resin, a plasticizer, and a reinforcement material, such as glass fibers, in combination with (B) a composition having adhesion to (A). Preferably (B) comprises a thermoplastic compound selected from the group consisting of PVC, plasticized PVC, styrene derivatives, urethane derivatives, acrylic derivatives, acrylonitrile derivatives, polyester derivatives, and mixtures thereof, with the most preferred composition being an unreinforced, plasticized polyvinyl halide composition. The composition article exhibits good strength, low sag at high use temperatures, and lowered coefficient of thermal expansion for use in contact with metal or polymeric substrates such as panels. The composition having a coefficient of thermal expansion not significantly different than the substrates in contact therewith, provides enhanced permanence of adhesion and sag resistance.

Articles from reinforced plasticized polyvinyl halide resin

Thermoplastic molding compositions and articles comprise immiscible thermoplastic polymer components and reinforcing fibers. The immiscible thermoplastic polymer components and the fibers are blended together under high shear conditions. The molding composition generally contains at least two phases and has an extremely smooth and fiber-free surface. Generally, very good physical properties are obtained such as high impact resistance, high heat distortion temperatures, high tensile modulus, high flex modulus, and the like. A desired blend of thermoplastic components is thermoplastic polyurethane and polyethyleneterephthalate with glass fibers.

The invention relates to a vinyl halide polymer composition suitable for outdoor use in the sunlight. The change in color as measured by .DELTA.E in articles made from the polymeric composition is found to be substantially lower than other compositions. The lower .DELTA.E provides a measurement for improved weatherability of the compositions in such applications as housing siding, window profiles, shutters and roof vents.

Weatherable rigid vinyl articles

Polyvinyl chloride articles such as bottles and films are provided which have a high degree of clarity, low haze, low blush, excellent color stability and which do not impart taste and odor to the contents of the article. A novel composition is used to form the articles. Said composition comprises at least one ingredient selected from the group having the formula:

Weatherable vinyl polymer compositions

The invention relates to a vinyl polymer composition suitable for outdoor use in the sunlight. The heat buildup in articles made from the composition is lowered without changing the ultraviolet protection or the color of the articles. This is accomplished by employing in the composition a black infrared reflecting pigment, such as a mixture of Cr.sub.2 O.sub.3 and Fe.sub.2 O.sub.3, and other infrared reflecting pigments.

An automated milking system includes galvanized metal stall structures, and in a parlor system a galvanized metal grate for the hind feet of a cow. An extraneous voltage protective unit is provided to prevent initiating electrical current flow in the cow because of small extraneous voltages which may be created in the milking system. The milking machines include a stainless steel claw and a plastic transfer hose to a similar steel collection pipe. A stainless steel pipe is inserted in the hose. A voltage compensator/sensor is coupled to the claw and the pipe insert to monitor the claw and generate a compensating voltage applied to the milking system to neutralize, compensate or otherwise effectively eliminate current flow through the cow at the udder. An A.C. signal monitor and a total signal monitor are coupled to the circuit to monitor and indicate stray alternating current voltages in the system, to monitor and indicate the sum of D.C. voltages and A.C. voltages in the system. A limit control may detect a voltage along a selected limit and disconnect the protective apparatus and indicate such condition.

The invention relates to obtaining weather-ability or U.V. light stability in vinyl polymeric translucent and transparent materials, which are designed for use in corrugated roofing, films for greenhouses, and the like. It has been found that by making a composite vinyl polymeric material where the main material or substrate is a transparent or translucent vinyl polymer and capping or coating it with a very thin film of a plasticized vinyl polymer containing a high level of a clear U.V. light absorber or stabilizer, such as, for example 1-cyano-2,2-diphenyl ethylacrylate, excellent weatherability is obtained. The important feature is the concentration of the clear U.V. stabilizer at the surface of the composite material which also results in the use of less U.V. stabilizer.
