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.

Thermoplastic resin composition having high rigidity and low coefficient of linear thermal expansion and molded article comprising same

A polypropylene resin composition includes: a base resin including a propylene homopolymer having a melt index of 20 g/10 min to 35 g/10 min measured at a temperature of 230&#xb0; C. and under a load of 2.16 kg and an ethylene-propylene copolymer having a melt index of 90 g/10 min to 100 g/10 min measured at a temperature of 230&#xb0; C. and under a load of 2.16 kg; a thermoplastic elastomer having a melt index of 10 g/10 min to 40 g/10 min measured at a temperature of 230&#xb0; C. and under a load of 2.16 kg; an inorganic filler; and a sodium phosphate-based nucleating agent.

Polypropylene resin composition and molded product thereof

A long carbon fiber reinforced thermoplastic resin composition for foam injection and a molded article manufactured using the same are provided. More particularly, the thermoplastic resin composition and the manufactured molded article may be capable of improving component assembly and stability by minimizing deformation after foam injection molding. Such composition and molded article can be utilized as a component for a vehicle structure such as a panoramic sunroof frame. Also provided herein is a low-density polyamide-6 polymer comprising a long carbon fiber reinforcing agent, a thermoplastic elastomer, a silane-based coupling agent and a sodium phosphate nucleating. The polymer is suitable for foam injection. The thermoplastic resin composition and molded article made of said composition are light weight and economic feasibility as well as having high stiffness, durability, dimensional stability, and a desirable injection appearance.
