摘要:
An assembly for covering and sealing a hole in a sheet panel including a sheet of cotton cloth tape having a plastic coated first side and an opposing second side including an adhesive surface adapted for covering the hole and adhering to the panel adjacent the hole. A preformed piece of sealing compound is adhered to the adhesive surface of the second side of the cloth tape adapted for filing and sealing the hole in the sheet panel.
摘要:
A method for preparing a laminate for a packaging material which has a great length and comprises an exterior printed ink layer, an aluminum vapor deposition film layer containing a linear low density polyethylene produced by a polymerization using a metallocene catalyst, an extrusion lamination layer of polyethylene and a carrier layer of paper or a substitute material for paper, characterized in that the method comprises vapor-depositing aluminum on one surface of a long film comprising a linear low density polyethylene produced by a polymerization using a metallocene catalyst, winding up the resultant aluminum-deposited film in a reel form temporarily, to thereby effect the direct contact of the face vapor-deposited with aluminum and the face of the film comprising a linear low density polyethylene, holding the reel for a given time, then drawing out the aluminum-deposited film from the reel and applying a melt lamination resin through extrusion lamination using a molten polyethylene between the face vapor-deposited with aluminum of the film and the carrier layer, to thereby laminate the aluminum vapor deposition film layer and the carrier layer, and forming an ink layer by printing on the face of the exterior side of the laminate.
摘要:
The invention relates to a floor covering as is frequently used in houses and apartments. The floor covering has on its underside a layer of thermoplastic material. This layer is connected in a fixed manner to the floor covering. The floor covering consists of wood, wood derivatives and/or synthetic materials. In order to produced said floor covering, the thermoplastic material is heated and applied, or rolled onto the underside of the floor covering. The latter exhibits excellent sound-proofing properties.
摘要:
A composite material consisting of a filler and a synthetic resin, comprising a core layer containing a filler weighing at least 0.7 times the product of a volume of the core layer and a bulk density of the filler and a thermosetting resin reinforced by long fibers parallel to each other in a longitudinal direction, wherein a surface layer is provided that is laminated so as to cover at least one face in a thickness direction of the core layer.
摘要:
This invention provides a thermoplastic multilayer resinous film in which two or more resinous materials form a plurality of very thin layers of substantially uniform thickness, the layers being substantially parallel, the contiguous adjacent layers being of different transparent thermoplastic resinous materials differing in refractive index, each of the outermost skin layers being at least 5 % of the total thickness of the film and the multilayer film containing a sufficient quantity of a pearlescent pigment to render it non-glossy.
摘要:
Paintable, thermoplastic polymer blends are prepared from (A) at least about 50 weight percent polyethylene, for example, high density polyethylene (HDPE), grafted with at least about 0.01 weight percent of an unsaturated organic compound, for example, maleic anhydride, and (B) a thermoplastic polymer containing polar groups, for example, a polyurethane or a polyester. Optionally, the grafted polyethylene of (A) can be diluted with an ungrated polyethylene, for example, ungrafted HDPE. These blends can be molded into various structural components, for example, automobile parts, and can be painted without the use of either a primer or a preliminary surface treatment, for example, chemical etching. The polyethylene blends also demonstrate excellent adhesion to various rigid polyurethane foams.
摘要:
A honeycombed panel made of thermoplastic resin, which is improved in shock resistance and by having a filling of resilience by both dynamic stability of the plastic resin material and compressed air or other compressed gas in the honeycombed cells of the panel.
摘要:
A container of thermoplastic material having a label (20) which substantially covers the visible outer surface of the body of the container. The container is made either as a single layer or multi-layer extrusion. The layer (12) of the container which is visible from the outside is made from 10 % to 100 % polyester and further comprises polypropylene which is present as an impurity.
