|
Heat resisting |
LETIAN PPS is one of the thermoplastic engineering plastics with highest usage temperature. Its thermal deformation temperature up to 260℃ and the long run temperature is in the range of 180~220℃, even up to 240℃ for short time. |
|
Chemical Resistance |
It is not reported that PPS can be dissolved by one solvent under 200℃. The resistance to organic acid, alkali and salt is excellent. |
|
Electrical Properties |
In high temperature, high humidity and high frequency environment, PPS have high volume resistivity, sheet resistivity and breakdown voltage, low dielectric constant and dissipation fraction. PPS is a kind of eminent insulation material. After modified treatment, it can be prepared as high-strength materials with good conductive properties. |
|
Mechanical Properties |
High rigidity, surface hardness with good resistance to creep and failure. |
|
Resistance to weather |
Good dimensional stability, low thermal expansion coefficient, creep deformation and water absorption, mold shrinkage. PPS is with good dimensional stability even in high temperature and humidity condition. |
|
Processing properties |
PPS is a kind of rigid polymer with high crystallinity. Fast crystalline growth velocity, short molding period, good flowability, easy to mold processing. |
|
Wear resistance |
With inorganic filling and carbon fiber, the wear resistance of PPS can be improved greatly. |
|
Flame retard properties |
PPS is a kind of self-extinguishing resin with flammability UL 94 V-0. |
