  • Patent number: 6620891
    Abstract: The present invention relates to a polypropylene resin composition comprising an ethylene-propylene copolymer having low molecular weight and an ethylene-propylene copolymer having high molecular weight but both have different constant melt flow rates. This polypropylene resin composition exhibits excellent physical properties such as impact resistance, heat resistance (thermal deformation resistance) and scratch resistance and thus, it can be substitutable for conventional ABS/PC resins and improve reclamation of automotive plastic parts such as housing assembly glove box parts due to deletion of coating process.

  • Patent number: 6590038
    Abstract: The present invention relates to a polypropylene resin composition and more particularly, to the polypropylene resin composition comprising a high crystalline polypropylene, an ethylene-&agr;-olefin elastomer, an inorganic filler, an organic peroxide and a crosslinking assistant. This polypropylene resin composition exhibits excellent scratch resistance, rigidity, heat resistance, and impact strength and thus, it can be suitable for automobile interior materials such as glove box, console, center crash pad and the like.

  • Publication number: 20020077396
    Abstract: The present invention relates to a polypropylene resin composition and more particularly, to the polypropylene resin composition comprising a high crystalline polypropylene, a polypropylene or polyethylene having low molecular weight, an inorganic filler and an anti-additive. The polypropylene resin of the present invention provides improved heat resistance, impact resistance and scratch resistance, so that it is suitable for substituting conventional polypropylenes used for automotive interior materials having several tens of grades, and further lowers manufacturing cost along with improving productivity and reclamation of used materials.

  • Publication number: 20020077406
    Abstract: The present invention relates to a polypropylene resin composition, more specifically to a polypropylene resin composition comprising ethylene-propylene block copolymer consisting of propylene polymer and ethylene-propylene copolymer with specific limit viscosity and content, ethylene-propylene copolymer rubber, ethylene a-olefin copolymer, inorganic filler, and polar group-consisting resin. It can be applied for peripheral automotive parts like crash pad without using adhesive because it has superior impact resistance and heat resistance, adhesion to urethane foam and forming contraction ratio comparable to that of ABS/PC resin.
