摘要： The invention is directed to a composite foam material that is alkaline and heat resistance. The composite foam material comprises a foam layer that having a film layer attached thereto and in which at least one of the film or foam layers includes a carbon free radical scavenger agent that is dispersed therein. The carbon free radical scavengers neutralize free radicals that are generated in the polymeric material (e.g., film or foam layer) and help prevent the degradation of the foam composite material. In particular, foam composite materials in accordance with the present invention can be used in underlayment applications in which exposure to heat can degrade the underlayment. As a result, the durability and useful life of the composite sheet material can be extended. In some embodiments of the present invention provides a floor underlayment material that overcomes many of the problems discussed above.

摘要： A composite material suitable for forming a recreational device, such as a snowboard or bodyboard includes a polyolefin foam base layer, a printed layer overlying the foam base layer, and a top layer overlying the printed layer, and wherein the layers are bonded together in the absence of adhesives. The composite material is produced by positioning a printed layer over a surface of a polyolefin foam base layer and extruding a top layer onto the printed layer with sufficient heat energy that the layers are fusion bonded together in the absence of adhesives to form a composite material. The printed layer comprises a thermoplastic polymeric film having a layer of printing on at least one of its surfaces. This film is fusion bonded to the foam base layer. The top layer comprises an extrusion coating of a transparent thermoplastic polymer that is fusion bonded to the printed layer.

摘要： An expanded cellular ethylenic polymer product is provided from an irradiated, noncross-linked linear ethylenic polymer. Linear ethylenic polymers can be irradiated at ambient conditions sufficient to introduce branching in the polymer in the absence of detectable cross-linking as indicated by the absence of gels. The irradiated linear ethylenic polymer is compatible with highly branched low density polyethylene and, when mixed therewith, produces a resin having a single broad based melting temperature range as determined by direct scanning calorimetry, which indicates that the polymers in the mixture have similar crystallization behavior suitable for producing low density foams by extrusion foaming. The linear polymers can be obtained from recycled shrink wrap film. Low densities of from 0.7 to less than 4 pcf can be achieved. The foams typically have improved tear resistance as compared to previous products prepared from low density polyethylene, at comparable low densities.

摘要： Ionomer present in a polyethylene resin from about 1 to 40% by weight of the resin produces superior extruded foam sheet products that approach the pore size and resiliency of foams prepared from chemical blowing agents. The results can be achieved at normal extrusion rates and on standard extrusion foaming equipment. Tear strength is improved so that collapsible foam packaging products can be produced in which the foam body is cut through except for a surface thereof that remains intact to provide a hinge or joint about which the cut foam bodies can be pivoted.

The foam is prepared using a propane blowing agent. The beneficial properties imparted to thicker grade and plank foams by a propane blowing agent can be achieved with up to as much as 75% by volume of either normal butane or isobutane or both in the blowing agent, depending on the polyolefin selected.

摘要： A method is disclosed for accelerating the removal of blowing agent from elongate, flexible polyolefin foam bodies, such as polyethylene foam sheeting, in the absence of substantial tension on the foam body so as to avoid breaks in the foam body. The elongate flexible foam body is introduced into a heating zone and draped over a plurality of substantially parallel bars in an endless path. Tension on the foam body is avoided because the foam loops are free hanging between these parallel bars. An endless drive means transports the parallel bars through the heating zone about the endless path, thereby transporting the foam body through the heating zone for removal of blowing agent. Forced heated air is blown over the exposed surface of the foam body at a pre-determined temperature and for a pre-determined time sufficient to remove a substantial portion of the residual blowing agent and to cause sufficient air to diffuse into the foam body so that there is no substantial reduction in the thickness of the foam.
摘要翻译：公开了一种用于在泡沫体上不存在实质张力的情况下加速从细长的柔性聚烯烃泡沫体（例如聚乙烯泡沫片）中除去发泡剂的方法，以避免泡沫体中的断裂。细长的柔性泡沫体被引入加热区域并且在多个基本上平行的条上悬挂在环形路径中。避免泡沫体上的张力，因为泡沫环自由悬挂在这些平行杆之间。环形驱动装置将平行杆通过围绕环形路径的加热区输送，从而将泡沫体输送通过加热区以除去发泡剂。强制加热的空气以预定的温度吹过泡沫体的暴露的表面，并且预定时间足以除去大部分的残留的发泡剂并引起足够的空气扩散到泡沫体中，使得泡沫的厚度没有显着降低。
