PPS is a professional term for plastics in industry called polyphenylene sulfide. From a physical appearance, it is a polymer with a smooth, hard, and brittle surface. So, what are the main properties of modified PPS plastics? Let's follow in the footsteps of Zhenghao to learn more!
From a chemical perspective, it has high crystallinity and is a special thermoplastic engineering plastic with excellent comprehensive performance in research and practical applications. Its biggest characteristics are high temperature resistance, corrosion resistance, and excellent mechanical properties, which make it suitable for many complex situations.
The modified PPS has extremely low dielectric constant and dielectric loss, and its surface resistivity and volume resistivity are insensitive to changes in frequency, temperature, and humidity. It can be said that polyphenylene sulfide is an excellent electrical insulation material. The modified PPS plastic has excellent thermal performance, and the addition of long glass fiber modification will result in higher thermal performance indicators.
The modified PPS plastic can maintain high mechanical properties and dimensional stability under long-term working and thermal loads, and can be used in high-temperature stress environments. At the same time, it also has good radiation resistance, which is a new material that cannot be compared to other engineering plastics. Moreover, the modified PPS plastic has excellent electrical insulation properties, and the volume resistivity of PPS grade materials with long carbon fibers is relatively low.
The modified PPS plastic maintains high mechanical properties and dimensional stability under long-term working and thermal loads. The addition of long glass fibers and long carbon fibers can improve the mechanical properties of modified PPS plastic, which can be used in high-temperature stress environments. In addition, its chemical stability is very good, except for being corroded by strong oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, aqua regia, etc., it is not corroded by most acidic and alkaline salts, and its chemical stability is close to PTFE.
