摘要:
The present disclosure provides a depth filter medium comprising at least one elastomeric nonwoven web strengthened by combination with one or more structural support layers. The resulting material is particularly useful in the field of filtration, wherein particulates captured within the elastomeric nonwoven web can be readily released, such as by applying pressure to the web through backwashing. The elastomeric nonwoven web advantageously can stretch under such pressure and return substantially to its original structure and shape upon the removal of the pressure, rendering the filter available for reuse.

The present invention provides a heat-shrinkable laminated film including at least two layers, in which the first layer is composed of at least one kind of a polylactic acid series resin as the main component and the second layer is composed of at least one kind of a polyolefin series resin as the main component. Heat shrinkage ratio of this film in the film main shrinking direction is 30% or more when dipped in warm water of 80°C for 10 seconds. Since this heat-shrinkable laminated film is made from a plant-derived resin, it promotes a use of biomass. Also, as this film exhibits excellent shrinkage property in low temperature, film rigidity, shrink finishing quality, and small natural shrinkage ratio, the film is suitably used for a molded product which requires heat shrinkage property, specifically, it is suitably used for shrinkable label.

Polymer composition comprising a) 10-99.99% by weight of at least one polyolefin, b) 0-50% by weight of a thermoplastic that is not a polyolefin, c) 0.005-1% by weight of per se known polymer additives, as well as an additional component chosen among d) at least one polybranched organic/inorganic hybrid polymer which has an inorganic core carrying organic branches, the core and branches forming a particulate structure, or/and e) a fat-soluble metal compound prepared by reacting a metal salt and an acidic, organic compound in a process in which a suitable oxidation agent ensures that all the metal in the end product is present in its highest stable oxidation state at standard conditions (25° C. and maximum 98% humidity).
摘要:
Partial areas of motor vehicle interiors, which have a three-dimensional surface contour, such as foot areas, lateral areas, wheel houses, sides of trunks, step protection devices underneath benches, etc. are generally trimmed with special molded parts, especially for optical reasons and sound-proofing purposes. Said special molded parts are expensive to produce. The invention therefore relates to a planar structure for trimming partial areas of an interior of a motor vehicle, which have a three-dimensional surface contour. Said planar structure comprises a layer of polyolefin foam and a layer made of a planar fabric, has an essentially flat shape, and is provided with linear openings in the form of perforations, needle holes, and/or punches. The inventive planar structure can be at least largely adapted to the three-dimensional shape of the partial area of a motor vehicle interior, which is to be trimmed, by bending or folding said planar structure along the linear openings and by elastically deforming the planar structure that is directly or indirectly fastened to the partial area.

A radiation-curable low stress relaxation elastomeric material with improved elastic and mechanical properties. The elastomeric material may be used alone or with skin layers to form elastomeric films, webs, laminates and products containing them.
摘要:
A cellular cushioning article comprises first and second multilayer films each having first and second outer layers; each of which contains an olefin-based polymer, and an inner O2-barrier layer. At least one of the O2-barrier layers contains recycled polyester. The first multilayer film is laminated to the second multilayer film so that a plurality of cells are formed between the first multilayer film and the second multilayer film. The cells can be discrete, fluid-filled cells produced by forming one or both of the films. Alternatively, the cushioning article can be an inflatable article in which the films are adhered to one another in a pattern to form a series of inflatable chambers connected by inflatable passageways terminating in a dead-end chamber. Processes for making the articles are also disclosed.
