Material Advantages Of PPS

PPS (polyphenylene sulfide) is a special engineering plastic with superior comprehensive performance, excellent high temperature resistance, chemical corrosion resistance, mechanical strength, and high cost-effectiveness. Its main advantages include: 1. Outstanding high temperature resistance: PPS can maintain good physical properties at high temperatures, has excellent heat resistance, and can be used for a long time at temperatures above 200 ° C. It is suitable for use in engine compartment components and battery systems of new energy vehicles. 2. Excellent mechanical performance: PPS has good mechanical strength and rigidity, can withstand large loads, and ensures the stability and reliability of automotive components during use. 3. Chemical corrosion resistance: PPS has strong corrosion resistance to various chemicals and is not easily corroded by environments such as acid, alkali, and freezing liquids, ensuring the long-term service life of automotive components. It is commonly used in various components of automotive thermal management systems. High temperature nylon PPA is also a high-performance engineering plastic, characterized by the following aspects: 1. Excellent heat resistance: PPA overcomes the weaknesses of traditional polyamide resins by introducing benzene rings into its basic skeleton, which has high heat resistance and a long-term use temperature of around 170 ° C. The hot deformation temperature is also very high (about 290 ℃), thus exhibiting excellent welding resistance. 2. Good rigidity: PPA can still maintain a relatively high modulus at high temperatures, for example, the modulus at 120 ℃ is 55% of the modulus at 23 ℃. That is to say, PPA can maintain stability and excellent rigidity over a wide temperature range.
