Polypropylene is more resistant to aging compared to polyester

Polypropylene is more resistant to aging compared to polyester.

1、 Characteristics of polypropylene and polyester

Polypropylene and polyester are both synthetic fibers with advantages such as light weight, flexibility, wear resistance, and chemical resistance. Polypropylene is more resistant to high temperatures, while polyester is softer and more comfortable, and is friendly to human skin.

2、 The aging resistance of polypropylene and polyester fibers

Polypropylene is a chemical fiber with good resistance to light, heat infiltration, oxidation, and oil, which can resist the effects of radiation aging and oxidative aging. When polyester is affected by radiation and thermal oxidation, its molecular chains are prone to breakage, leading to aging.

3、 Comparison of Polypropylene and Polyester in Practical Applications

Polypropylene has a wide range of applications and can be used to manufacture high-temperature and corrosion-resistant chemical equipment, wire and cable sheaths, automotive parts, etc; Polyester is widely used in the textile industry, such as weaving knitwear, carpets, suede fabrics, needle felt, etc.

4、 Conclusion

Compared to polyester, polypropylene is more resistant to aging, but both fibers have their own advantages and disadvantages, and their application scenarios are different. In practical applications, suitable materials need to be selected according to specific requirements.
