Material Sheet Introduction of PPS (Polyphenylensulfid)
Polyphenylensulfid, abbreviated as PPS, is a high-performance engineering plastic with the following key characteristics:
Basic Information
- English Name: Polyphenylensulfid
- Abbreviation: PPS
Physical Properties
- Density: 1.34
- Operating Temperature Range: -40℃ - 180℃
- Melting Point: 235℃
- Brittleness Temperature: 85 - 95℃
- Heat Deflection Temperature: 285℃
- Water Absorption: 0.02
Chemical Resistance
- Acid Resistance: Resistant to weak acids, partially resistant to strong acids, and not resistant to oxidizing acids
- Alkali Resistance: Resistant to weak and strong alkalis
- Solvent Resistance: Resistant to alcohol and saturated aliphatic hydrocarbons, partially resistant to aromatic hydrocarbons, fats and oils
Flame Retardancy and Combustion Characteristics
PPS is flame retardant. The self-extinguishing flame burns brightly and smells of rotten eggs
Other Properties
- Weather Resistance: Not resistant to UV and weathering, cannot be supplied colored. Additives are used to increase flexibility and prevent brittleness
- Mechanical Properties: Rockwell Hardness > 40
