THERMOPLASTIC RESIN COMPOSITION HAVING HIGH RIGIDITY AND LOW COEFFICIENT OF LINEAR THERMAL EXPANSION AND MOLDED ARTICLE COMPRISING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17858565 titled 'THERMOPLASTIC RESIN COMPOSITION HAVING HIGH RIGIDITY AND LOW COEFFICIENT OF LINEAR THERMAL EXPANSION AND MOLDED ARTICLE COMPRISING SAME
Simplified Explanation
The present disclosure describes a thermoplastic resin composition that has high rigidity and a low coefficient of linear thermal expansion. It also includes a molded article made from this composition. The composition consists of a first propylene-ethylene copolymer, a second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent. This composition improves the mechanical rigidity, impact resistance, and dimensional stability of the molded article. Even when the article is made with a low thickness for weight reduction, it still maintains excellent processability, high tensile strength, a high flexural modulus, and high impact strength.
- The thermoplastic resin composition has high rigidity and a low coefficient of linear thermal expansion.
- It includes a first and second propylene-ethylene copolymer, a thermoplastic elastomer, an inorganic filler, and a sodium-phosphate-based nucleating agent.
- The composition improves mechanical rigidity, impact resistance, and dimensional stability of the molded article.
- The molded article made from this composition has excellent processability, high tensile strength, a high flexural modulus, and high impact strength.
Potential Applications
This technology can be used in various industries and applications, including:
- Automotive: for lightweight and rigid components in vehicles.
- Electronics: for high-performance and dimensionally stable parts in electronic devices.

Original Abstract Submitted
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.
