  • Patent number: 11976176
    Abstract: A method for producing a film including at least 20 wt % thermoplastic polymer and 50 to 75 wt % inorganic filler, and including the steps of: providing the mixture, melting the mixture, producing a thin layer from the mixture, cooling the thin layer, producing a film, stretching the film in the longitudinal direction and in the transverse direction, wherein the particle size of the inorganic filler is at most 5 ?m and the stretch ratio in the longitudinal direction and in the transverse direction is at least 3.5. The disclosure further relates to films produced by the method and to the use thereof.

  • Patent number: 11965506
    Abstract: A scroll compressor includes a compressor housing, a high-pressure chamber, a low-pressure chamber, an oil return channel having an oil return throttle arranged therein, a driven eccentric unit, a fixed scroll, an orbiting displacement scroll arranged on the driven eccentric unit which interacts with the fixed scroll, a sliding disk arranged between the orbiting displacement scroll and the compressor housing, a back-pressure chamber arranged adjacent to the orbiting displacement scroll, and a gas connecting channel having a gas connecting throttle arranged therein. The oil return channel fluidically connects the high-pressure chamber with the low-pressure chamber. The gas connecting channel fluidically connects the back-pressure chamber with the high-pressure chamber. The oil return channel and/or the gas connecting channel extends through the sliding disk. The sliding disk includes the oil return throttle and/or the gas connecting throttle.

  • Publication number: 20230087287
    Abstract: A biaxially-oriented film for thermoforming is disclosed including at least 75% by weight polyethylene and at least 95% by weight polyolefins, based on the total mass of the film. The polyethylene has an elongation at break of at least 7 in the stress-strain diagram, wherein the stress-strain diagram is measured at a temperature of 10° C. below the melting point of the polyethylene and the melting point is determined by differential scanning calorimetry using a heating rate of 10° C. per minute. A process for producing such films and to the use thereof are disclosed. A process for producing shaped bodies from such films and to the shaped bodies themselves are disclosed.
