| 20100092791 | SIMULTANEOUSLY DRAWN OPAQUE FILM MADE OF PLA - The present invention relates to simultaneously drawn opaque biaxially oriented film made of at least one cycloolefin copolymer (COC) containing layer. The COC is preferably at a concentration of 0.5 to 30% by weight, based on the layer. The invention further relates to an opaque, biaxially oriented polyhydroxycarboxylic acid film containing at least one layer containing a polymer based on hydroxycarboxylic acids and a cycloolefin copolymer (COC). The invention further relates to a process for producing the PHC film and the use thereof. | 04-15-2010 |
| 20100151219 | SIMULTANEOUSLY ORIENTED PLA FILM WITH IMPROVED MECHANICAL PROPERTIES - The present invention relates to a biaxially oriented polyhydroxycarboxylic acid film composed of at least one layer containing a polymer based on hydroxycarboxylic acid. The film is notable for good mechanical properties such as high breaking strength and modulus of elasticity. The invention further relates to a process for producing the PHC film and the use thereof. | 06-17-2010 |
| 20110064934 | SINGLE-LAYER POLYPROPYLENE MEMBRANE FILM FOR BATTERIES, HAVING A SHUT-OFF FUNCTION - The invention relates to a biaxially oriented, single-layer microporous film which has a shut-off function and is made of propylene homopolymer, propylene block copolymer I and β-nucleation agent. The melting range of the propylene block copolymer I starts at a temperature ranging from 50 to 120° C. The invention also relates to using the film as a separator in primary or secondary battery. | 03-17-2011 |
| 20110064989 | MEMBRANE FILE FOR BATTERIES, HAVING A SHUT-OFF FUNCTION - The invention relates to a biaxially oriented microporous film composed of at least two coextruded layers encompassing an external shut-off layer and another layer, wherein both layers contain a mixture of propylene homopolymer and propylene block copolymer and β-nucleation agent. The propylene block copolymer I of the other layer has a melting point exceeding 140° C. and the propylene block copolymer II of the external shut-off layer has a melting range starting at a temperature ranging from 50 to 120° C. The melting point of the propylene block copolymer I is greater than the melting point of the propylene block copolymer II. The film can be used as a separator in a primary or secondary battery. | 03-17-2011 |
| 20110064990 | MICRO-POROUS MULTI-LAYER MEMBRANE FILM BASED ON POLYPROPYLENE FOR BATTERIES WITH A CUT-OFF FUNCTION - The invention relates to a biaxially oriented microporous film composed of at least three coextruded layers encompassing an internal cut-off layer and two external layers, wherein all three layers contain a mixture of propylene homopolymer and propylene block copolymer and β-nucleation agent. The propylene block copolymer I of the external layers has a melting point exceeding 140° C. and the propylene block copolymer II of the internal layer has a melting range starting at a temperature ranging from 50 to 120° C. and the melting point of the propylene block copolymer I is greater than the melting point of the propylene block copolymer II. | 03-17-2011 |
