Solid state draw a laminated polymer billet containing two or more polymer compositions laminated to one another to prepare an oriented polymer composition.

A molding tool and method for producing an interior trim part. A cavity is embodied between a first element and a second element, and a slide is displaceably connected to the first element. A decorative layer is arranged on the first element and a backing is arranged on the second element. A foamable mixture is added to the hollow area between the backing and a reverse side of the decorative layer, such that a foam layer fills the hollow area. A distance between the first element and the second element is increased to enlarge the hollow area. During this process, the slide is pressed against a side facing away from the reverse side of the decorative layer, such that the hollow area is sealed with the reverse side of the decorative layer pressed against a lateral surface of the backing and/or against a lateral surface of the second element.

An insulation device for a receiving area of a household appliance includes an insulation element made of a viscoelastic polyurethane foam for acoustically insulating the receiving area, and a stiffening element stiffening the insulation element and firmly connected to the insulation element.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

Methods of making recyclable heavy-gauge films are provided. The methods of the present disclosure involve bonding the inner layers of a coextruded blown film together such that the film is sufficiently thick enough for it to be oriented in the MDO section using the typical 5:1 orientation ratio and result in a film with twice the gauge typically made by the MDO process (while maintaining acceptable stiffness and dimensional rigidity). Recyclable heavy-gauge films formed by the methods are also provided.

In a polypropylene-based foamed molded body of the present invention, a density which is measured on the basis of ISO1183 is greater than or equal to 0.15 g/cm.sup.3 and less than or equal to 0.54 g/cm.sup.3, thermal resistance (R) at 30° C. in a thickness direction which is measured on the basis of ASTM E1530 is greater than or equal to 0.020 m.sup.2.Math.K/W and less than or equal to 0.125 m.sup.2.Math.K/W, thermal capacity per unit area (Q) at 30° C. is greater than or equal to 1.0 kJ/m.sup.2.Math.K and less than or equal to 2.5 kJ/m.sup.2.Math.K, and Expression 1 described below is satisfied.

Q>1/(4×R.sup.1/2)  (Expression 1)

A bead foam is made of thermoplastic polyurethane, a styrene polymer, and an impact modifier. Moldings can be produced from the bead foam and processes for the production of the bead foams and moldings can be utilized. The moldings can be used for shoe intermediate soles, shoe insoles, shoe combisoles, cushioning elements for shoes, bicycle saddles, bicycle tires, damping elements, cushioning, mattresses, underlays, grips, protective films, in components in the automobile-interior sector or automobile-exterior sector, balls and sports equipment, or as floorcovering.

An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.

The present invention deals with a process for producing pellets from olefin copolymers. The process comprises: (i) melting the olefin copolymer in an extruder; (ii) extruding the molten olefin copolymer through a die plate into a pellet water bath in a pelletiser thereby producing strands of the olefin copolymer; (iii) cutting the strands of the olefin copolymer in the pelletiser into pellets; and (iv) drying the pellets. The pellet water in the pelletiser contains from 0.1 to 5% by weight of a colloidal silica based on the weight of the water.

A compound type polyurethane toilet seat, comprising a surface coating layer, a positioning structure and a seat support; the surface coating layer is made from polyurethane and seamlessly covers the outer surface of the seat support by means of the positioning structure; the preparation process comprises: step 1, spraying a release agent and an in-mold paint in a cavity of a mold; step 2, cleaning the surface of the seat support; step 3, polishing or abrasive blasting; step 4, thermally treating the seat support; step 5, spraying the release agent in the cavity of the mold, and installing the seat support in the cavity of the mold; step 6, injecting a polyurethane raw material into the cavity of the mold, and shaking the mold; step 7, foaming the polyurethane raw material.
