  • POLYPROPYLENE COMPOSITION, PREPARATION METHOD AND USE THEREOF
    Publication number: 20230013717
    Abstract: A polypropylene composition comprising the following components in parts by weight: 40-99 parts of a polypropylene resin; 15-30 parts of an ethylene-? olefin copolymer; 0.2-1 part of an antimicrobial agent; and 1-3 parts of a polypropylene grafted polydimethylsiloxane is provided. By controlling a melt index of an elastomer, distribution of the modified polydimethylsiloxane and antimicrobial agent can be improved, thus improving antimicrobial and stain-resistant effects of the polypropylene composition.

  • POLYPROPYLENE COMPOSITION AND PREPARATION METHOD THEREFOR
    Publication number: 20230002604
    Abstract: The present invention discloses a polypropylene composition. A resin matrix is composed of copolymerized polypropylene and branched polyethylene with special parameters, such that the resin matrix has a low crystallization tendency, thereby improving spraying adhesion of a surface of the resin matrix. A polyolefin elastomer (POE) in bimodal distribution is further used to improve the appearance after molding.

  • USE OF ETHOXYAMIDE POLYMER AS DELAY COMBUSTION AGENT, LOW-ODOR COMBUSTION-DELAYING POLYOLEFIN COMPOSITION AND PREPARATION METHOD THEREOF
    Publication number: 20210163709
    Abstract: Disclosed is a low-odor combustion-delaying polyolefin composition, which includes the following components by weight percentage: 56% to 99.7% of polyolefin; 0.3% to 2% of an ethoxyamide polymer; 0% to 2% of a delay combustion synergist; and 0% to 40% of a filler. Disclosed is also a use of the ethoxyamide polymer as a delay combustion agent in the polyolefin composition.
