摘要:
A foamed thermoplastic material includes a thermoplastic material exhibiting, in its unfoamed state, a particular flammability index, flame growth rate, and specific extinction area. The foamed thermoplastic material further includes a plurality of cells having a number average mean diameter of 5 to 150 micrometers present in an amount effective to provide the foamed thermoplastic material with a density that is 10 to 90 percent of the density of the unfoamed thermoplastic material. The foamed thermoplastic material exhibits a desirable tensile elongation and dielectric constant. A process for forming the foamed thermoplastic material, articles including the foamed thermoplastic material, and an article-forming process are also described.
摘要:
A process for producing a thermoplastic resin foam, comprising at least steps (A) and (B): (A) subjecting a molten thermoplastic resin to a first gas obtained from a first compound at a first temperature; (B) subjecting the foamed resin obtained in step (A) to a second gas obtained from a second compound at a second temperature; wherein the second temperature is above the first temperature.
摘要:
Die Erfindung betrifft ein Folienlaminat (1), umfassend zumindest eine kompakte Dekorschicht (2) mit einer Lackschicht (3) auf der Oberseite und einer Schaumschicht (4) auf der Unterseite, wobei die Schaumschicht (4) eine Dichte von mehr als 500 kg/m3 aufweist. Ferner betrifft die Erfindung die Verwendung eines solchen Folienlaminates (1) für die Beschichtung von Bauteilen für die Innenverkleidung von Kraftfahrzeugen und Innenverkleidungsteile von Kraftfahrzeugen, die mit einem solchen Folienlaminat (1) versehen sind. Bei tiefziehbaren Folienlaminaten (1) für die Beschichtung von Innen verkleidungsteilen für ein Kraftfahrzeug im Bereich der Airbag-Abdeckungen bzw. im Bereich der Aufreißnähte der Airbag-Abdeckungen, die ohne Schwächungslinien auskommen, basiert die Schaumschicht (4) auf einer Zusammensetzung, die a) 15 bis 60 Gewichtsteile zumindest eines thermoplastischen Vulkanisates (TPV) b) 15 bis 35 Gewichtsteile zumindest eines High Melt Strength Polyolefins (HMS Polyolefins) und c) 30 bis 60 Gewichtsteile zumindest eines Low Density Polyethylens (LDPE) enthält, wobei sich die Anteile von a), b) und c) zu 100 addieren.

摘要:
Processing aid for aiding in orienting an extruded film layer including a preponderance, by weight, of a high crystalline polypropylene is a crystalline polypropylene wax. An oriented film layer including a blend of crystalline polypropylene wax and high crystallinity polypropylene homopolymer is part of the invention. The invention includes a method of forming an oriented film layer including a preponderance by weight of a high crystallinity polypropylene and includes the steps of blending a high crystallinity polypropylene with a crystalline polypropylene wax, directing the blend through an extruder to form a film layer and then orienting the film layer. The invention includes a biaxially oriented, multi-layer film including a base layer and at least one skin layer. The base layer includes a blend of crystalline metallocene catalyzed polypropylene wax and a high crystallinity polypropylene.
