  • Polypropylene random copolymer composition for cold and hot water pipe applications
    Patent number: 12071535
    Abstract: Polypropylene polymer compositions are disclosed that can be used to produce different types of molded articles, such as extruded piping structures. The polypropylene polymer composition contains a polypropylene random copolymer in combination with a property enhancing agent. The property enhancing agent is incorporated into the polymer composition so that the composition has relatively high impact resistance properties in combination with a relatively high flexural modulus.
    Type: Grant
    Filed: October 23, 2019
    Date of Patent: August 27, 2024
    Assignee: W.R. Grace & Co.—Conn.
    Inventors: Jose Manu Rego, Michelle Ni Paine, Zhiru Ma

  • Painted polyolefin articles
    Patent number: 8530019
    Abstract: Articles having a Shore A hardness of 50 to 95 and made from polyolefin compositions comprising an ethylene-alpha-olefin interpolymer (random or block or a mixture of the two) are paintable without the need for a primer or other surface treatment with paints free of phthalate-based plasticizer and designed to paint SBS- or SEBS-type rubber based compositions. These polyolefin compositions are free of (1) phthalate-based plasticizer, (2) halogen-containing polymer, and (3) leachable, small polymeric units derived from styrene monomer. In addition, the content of the alpha-olefin in the polyolefin composition is at least 9.7 mole percent.
