Definitions
- the present invention relates to a thermoplastic resin composition and a molded article manufactured therefrom.
- Polycarbonate resin is one of the engineering plastics and is a widely used material in the plastics industry.
- Polycarbonate resin has a glass transition temperature (Tg) of approximately 150°C due to its bulky molecular structure, such as bisphenol-A, and thus exhibits high heat resistance.
- Tg glass transition temperature
- the carbonyl group of the carbonate group has high rotational mobility, which provides flexibility and rigidity to the polycarbonate resin.
- amorphous polymer it has excellent transparency, impact resistance, and compatibility with other resins.
- polycarbonate resin has a disadvantage of low fluidity, so it is also widely used in the form of alloys with various resins to improve workability and post-processing.
- polycarbonate/polyethylene terephthalate alloy resin has excellent durability, formability, heat resistance, and impact resistance, and is applied to a wide range of fields such as electrical/electronic, automobile, construction, and other living materials, and is particularly attracting attention as a material that can replace metal parts when used as an automobile exterior material.
- polycarbonate/polyethylene terephthalate alloy resins have a problem in that they lack dimensional stability, making it difficult to completely replace metal parts used in automobiles. Accordingly, a method of supplementing dimensional stability by reinforcing mineral fillers in polycarbonate/polyethylene terephthalate alloy resins has been attempted, but this method has a problem in that impact resistance decreases due to reinforcement of mineral fillers.
- thermoplastic resin composition having excellent impact resistance and dimensional stability.
- the present invention provides a thermoplastic resin composition having excellent impact resistance and dimensional stability, and a molded product using the same.
