Thermoplastic composition, comprising at least components (i) to (iii): (i) from 10 to 50% by weight of a combination of at least one first ethylene polymer (A) and at least one second ethylene polymer (B), wherein (A) is selected such as to exhibit (a) a density of from 0.87 g/cm-0.90 g/cmas determined according to ASTM D792; (&#x3b2;) a melt flow index of from 0.3 g/10 min-5 g/10 min as determined according to ASTM D1238 (190&#xb0; C./2.16 kg); (&#x3b3;) a flexural modulus of from 5 to 60 MPa measured according to ASTM D790; and wherein (B) is selected such as to exhibit (a) a density of from 0.90 g/cm-0.92 g/cmas determined according to ASTM D792; (&#x3b2;) a melt flow index of from 0.3 g/10 min-10 g/10 min as determined according to ASTM D1238 (190&#xb0; C./2.16 kg); (&#x3b3;) a flexural modulus which is higher than that of (A); (ii) from 35-90% by weight of inorganic particles as filler; (iii) from 0.05-20% by weight of a liquid (at 23&#xb0; C.) as a plasticizer for the at least one first ethylene polymer (A) and/or the at least one second ethylene polymer (B); the % by weight of components (i) to (iii) being based on the total weight of the composition.

Thermoplastic composition comprising polyethylene, manufacture and use thereof

A pressurized steam molded multilayer lining for heat and sound insulation comprising a first layer forming a reinforcement layer made of a blended web of polyamide matrix material in the form of powder or fibers or flakes and reinforcement fibers, and at least a second layer chosen from an open cell foam layer, or a heat reflecting layer, or a second reinforcement layer made of a blended web of polyamide matrix material in the form of powder or fibers or flakes and reinforcement fibers, and whereby due to the pressurized steam molding, all layers are laminated together and all available blended webs are consolidated to form porous reinforcement layers.

Moulded multilayer lining for heat and sound insulation

Production method for a multilayer lining for thermal and sound insulation with the steps of blending reinforcement fibers and polyamide matrix material, in the form of fibers, flakes or powder, and forming a web of said blend; layering said blended web and at least an additional layer chosen from an open cell foam layer, a heat reflective layer, or another of said blended web inside a mold; treating the stacked multilayer material with pressurized saturated steam, such that the polyamide matrix material in the blended web is melting at a temperature under steam pressure that is lower than the melting temperature of the polyamide matrix according to DSC, thereby binding the reinforcement fibers together thus consolidating the blended web forming a porous reinforcement layer, and all layers of the multilayer are laminated together.
