  • COMPRESSORS INCLUDING POLYMERIC COMPONENTS
    Publication number: 20160341198
    Abstract: Improvements in compressor manufacture are achieved by utilizing polymeric components which retain at least 90% of their dimensions after being exposed to a mixture of refrigerants and/or lubricants for 30 days at 60° C. Polymeric materials include (i) polyetherimides, (ii) polyphenylene sulfides, (iii) polyketones, (iv) polysulfones, (v) liquid crystal polymers, and (vi) combinations thereof. Metal coatings on the polymers are the preferred embodiments for housings.

  • Thin wall profile having outer weather band ultra violet light resistant layer
    Patent number: 5522196
    Abstract: This invention is directed to an extruded thermoplastic, thin-walled, high definition profile structure having a central hollow cross sectional member with at least two flange members extending perpendicularly therefrom and longitudinally therewith wherein at least one flange member extends from one side of the cross sectional member and at least one flange member extends from the other side thereof. Preferably, there are three flange members extending from one side forming channel-like recesses and one flange extending from the other side of the cross sectional member.Also included herein are particular thermoplastic resins that can be employed in making the profile structure of this invention. For example, the profile can be a composite comprising a substrate of acrylonitrile-butadiene-styrene and a thin outer layer of polyvinyl chloride or a blend of polyvinyl chloride and acrylic-styrene-acrylonitrile.
