  • Patent number: 9718258
    Abstract: A film that contains a core layer positioned adjacent to an outer layer is provided. The core layer contains a relatively high percentage of thermoplastic biopolymers that are both biodegradable and renewable. Despite being biodegradable and renewable, many biopolymers tend to be relatively stiff in nature. The present inventors have discovered, however, that through selective control over the components in the core and outer layers, a film can be readily formed having good mechanical properties. Among other things, this is accomplished by blending the biopolymer in the core layer with a polyolefin. A polyolefin is also employed in the outer layer. In addition to providing functionality to the film (e.g., heat sealing, printing, etc.), the polyolefin-containing outer layer also helps counteract the stiffness of the biopolymer in the core layer, and helps improve processability, stiffness, and ductility.

    Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, activated carbon, and water are provided. The activated carbon acts as both a water absorbent and carrier for the water. The activated carbon is able to control and increase cell size even in the presence of carbon dioxide, HFCs, and/or infrared attenuating agents. Additionally, the activated carbon permits a desired amount of water to be introduced into the polymer melt. By controlling the amount of activated carbon and its water content during an extrusion process, a broad range of cell sizes can be obtained in the extruded product. In exemplary embodiments, the activated carbon is added to a primary extruder and water is directly injected into a secondary extruder. Alternatively, the activated carbon is compounded with a polymer resin, pre-hydrated by conditioning or steam impregnation, and added to a primary or secondary extruder.

  • Patent number: 7927694
    Abstract: It comprises three layers: a first layer of plastic material that provides the whole with mechanical strength, a second intermediate layer of foam forming a union between the first and second layer, and a third layer of impermeable plastic material and is characterized in that the first layer (2) is mase on an elastomeric polyolefin of high strength and elasticity, in that the second layer (3) is of closed-cell, physically or chemically cross-linked polyethylene foam, and in that the third layer (4) is of polyolefin with high tear resistance. A light waterproofing sheet is obtained which withstands extreme meteorological conditions, is resistant to chemical agents, while it also has optimum mechanical properties at a lower thickness thanks to the material of which the first layer is comprised and unlike other sheets existing it has no ageing limit, which means that once the sheets have been fitted they do not have to be replaced.
