Polyphenylene sulfide (PPS) is a semi-crystalline, high-temperature engineering thermoplastic. It is a rigid and opaque polymer. It has a high melting point (280°C). It consists of para-phenylene units alternating with sulfide linkages.

it provides excellent properties like:

• Exceptional mechanical strength
• Dimensional stability
• Electrical insulation properties
• Resistance to flame, chemical, and high temperature

 

Properties

•  

1. Crystal Structure and Physical Properties: PPS is a semi-crystalline polymer.
   • The unit cell is orthorombic (a=0.867 nm, b=0.561 nm, c=1.026 nm)
   • The heat of fusion for an ideal PPS crystal was calculated as 112 J/g
   • Depending on the thermal history, molecular weight, and cross-linked status (linear or not) the degree of crystallinity ranges from 0.30 to 0.45%
   • Amorphous and crosslinked PPS can be prepared by:
     • Heating the material above the melting temperature
     • Cooling it to around 30°C below the melting temperature, and
     • Holding it for several hours in the presence of air


2. Dimensional Stability: PPS is an ideal material of choice to produce complex parts with very tight tolerances. The polymer exhibits excellent dimensional stability even when used under high temperature and high humidity conditions.


3. Electrical Properties: PPS has excellent electrical insulation properties. High volume resistivity and insulation resistance are retained after exposure to high-humidity environments. It has a less pronounced O₂ sensitivity. It can be conveniently doped to get high conductivity.


4. Thermal Properties and Fire Resistance: PPS is a high-temperature specialty polymer. Most of the PPS compounds pass UL94V-0 standard without adding flame retardant. PPS can be resistant at 260°C for a short time and used below 200°C for a long time.


5. Mechanical Properties: PPS has high strength, high rigidity, and low degradation characteristics even in high-temperature conditions. It also shows excellent fatigue endurance and creep resistance. PPS has a lower elongation to break, a higher cost, and is rather brittle. Today, PPS is available in different forms and grades such as compounds, fibers, filaments, films and coatings.


6. Chemical Properties: PPS has good chemical resistance. If cured, it is unaffected by alcohols, ketones, chlorinated aliphatic compounds, esters, liquid ammonia, etc. It also tends to be affected by dilute HCl, nitric acids, and concentrated sulfuric acid. It is insensitive to moisture and has good weatherability.
