Analysis of the Advantages of Polyphenylene Sulfide Staple Fiber (PPS)

Jul 05,2023

Polyphenylene sulfide staple fiber (pps) is a super high performance fiber with excellent corrosion resistance, flame retardancy, high temperature resistance, insulation and other properties.

1. Excellent heat resistance: it has excellent strength, rigidity and fatigue resistance at high temperature, it can be used continuously at 200~240°C, it is stable in air or nitrogen below 400°C, and basically has no weight loss. It can be used for a long time at 190°C.

2. Excellent corrosion resistance: chemical corrosion resistance is similar to polytetrafluoroethylene (PTFE), known as the "King of Plastics", and can resist the erosion of acids, alkalis, chlorine, hydrocarbons, ketones, alcohols, esters and other chemicals , insoluble in any solvent at 200°C.

3. Excellent flame retardant performance: the limiting oxygen index loi value is 34, it can burn on the flame, but it will not drip, and it is self-extinguishing when it is away from the fire. The smoke rate is lower than that of halogenated polymers, and there is no need to add flame retardants It can reach the ul-94v-0 standard.

4. Excellent electrical properties: dielectric constant 3.9~5.1, dielectric strength (breakdown strength) 13~17kv/mm, good insulation can still be maintained under high temperature, high humidity, frequency conversion and other conditions.

5. Good physical properties: This product has good physical properties.
