  • Publication number: 20230203256
    Abstract: Disclosed are a polypropylene resin composition and a molded article including the same. The polypropylene resin composition may include a polypropylene resin, glass fiber, a non-halogen flame retardant, a compatibilizer, and sodium salt ionomer such that the resin composition may provide substantially improved mechanical properties such as tensile strength, impact strength, and flexural modulus, and excellent flame retardancy and flame retardant stability over time.

  • Publication number: 20230024056
    Abstract: The present disclosure provides a thermoplastic resin composition having high rigidity and a low coefficient of linear thermal expansion and a molded article including the same. The thermoplastic resin composition includes a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent as appropriate, and thus a molded article produced therefrom can exhibit improved mechanical rigidity, impact resistance, and dimensional stability. Even when formed to a low thickness for weight reduction, the molded article can be imparted with excellent processability, high tensile strength, a high flexural modulus, and high impact strength.

  • Publication number: 20220106447
    Abstract: Disclosed herein are a long glass fiber reinforced thermoplastic resin composition and a molded article including the same. Specifically, the thermoplastic resin composition may include 30% to 70% by weight of polyamide, 20% to 60% by weight of a reinforcing agent which contains a glass fiber and has a flat-plate shape, and 1% to 5% by weight of a silane-based coupling agent.
