摘要： Disclosed are processes for making olefin polymer foam structures with 1,1-difluoroethane (HFC-152a). One foam structure is comprised of an ethylene polymer material, and is blown with a mixture of isobutane and 1,1-difluoroethane. Another foam structure has a cross section of 2 or more inches (5 or more centimeters) in one dimension and 18 or more inches (46 or more centimeters) in the other dimension, and is blown with 75 mole percent or more HFC-152a. Another foam structure is in coalesced strand form with a density of 16 to 48 kilograms per cubic meter, and is blown with a first blowing agent of 20 to 90 mole percent 1,1-difluoroethane and 80 to 10 mole percent of a second blowing agent selected from isobutane, n-butane, and propane.

The extrusion direction of the thermoplastic foam is aligned substantially parallel with the direction in which impact resistance is desired to provide an energy absorbing article exhibiting a high ratio of compressive strength to weight. In accordance with a particular aspect of this invention, the thermoplatic foams may be prepared by the extrusion foaming of a molten thermoplastic composition utilizing a die including a mulitiplicity of orifices. In additon to coextrudates comprising coalescend strand foams having foam strands of two or more different densities, the extruded thermoplastic foams exhibiting antisotropic strength properties which may be utilized in accordance with the principles of this invention include coextrudates including foam strands and a unitary (integral piece) interleaving profile of an unfoamed thermoplastic.

摘要： A vehicle having an improved headliner. The headliner comprises a thermoformed core layer. The core layer comprises an extruded thermoplastic foam and optionally one or more adjacent layers of a substantially non-foamed thermoplastic. The core layer is substantially free of thermoset materials and preferably free of glass or fiberglass mattes or scrim. A decorative layer such a felt layer or a fabric layer is preferably laminated to the core layer. The headliner is substantially resistant to sagging and able to substantially maintain its thermoformed shape when installed in the vehicle. There is also a process for assembling or making a headliner and installing it in a vehicle.
