High quality natural PPS board customized plastic PPS sheet

PPS（Polyphenylene sulfide） is a semi-crystalline high performance thermoplastic with optimised tribological

properties for demanding bearing and friction requirements. The molecular structure of PPS is comparatively

simple, and the main molecular chain is alternately arrayed by benzene rings and sulfuratoms, lots of rings

and sulfur and sulfuratoms supplies PPS with the rigidity resistance as well as the pliancy resistance. The inner

symme trical molecular structure makes PPS easily crystal, non-polarity, good electrical resistance and low water

absorption and so on.PPS is widely used in precision and chemical engineering, plant construction, aircraft and

aerospace industry.

PPS advantages

01 Heat resistant and flame retardant

PPS has excellent heat resistance, the melting point is more than 280 ℃ . When suffering 1.8 MPA load, its

thermal deformation temperature is more than 260 ℃ . Common long-term usage temperature is 220-240 ℃,

PPS resin has good flame resistance, no need to add any flame retardants then reach UL94 level 0 and 5-V

standard, when burning, smoke output is very low.

02 Mechanical properties

PPS resin mechanical strength is not high, but afterreinforced glass fiber, carbon fiber or mineral stuff filling, its

strength and stiffness are multiplied, and having excellent resistance to creep and fatigue. Its surface hardness

is high, rockwell hardness > 100HR , tensile strength reach 170 mpa, bending strength > 220MPA, notched impact

strength > 16MPA, bending modulus > 3.5 x 10^4

03 Chemical character

PPS is excellent chemical resistance, just behind ptfe material, it won\'t dissolve in any organic solvents below 200 ℃,

except strong oxidizing acid, it is also strong resistance to inorganic acid, alkali and salt . especially it is also stable in

variety of radiation.
