Characteristics of PPS –Injection Molding manufacturing material in china
PPS material is a polymer compound having a phenyl group on the main chain. Due to its structure and the sulfur is alternately connected to a benzene ring. The molecular chain having high rigidity and regularity. PPS is a crystalline polymer and thus. It has many excellent properties. Such as heat resistance, rigidity, flame retardancy, and electrical insulation. Lone pair electrons of the sulfur atom such PPS and glass fiber. An inorganic filler, and a metal having a good affinity for the easy-reinforced composite made from a variety of materials and alloys.
Compared with ABS, PP, PE, NYLON. PC compared with the commonly used materials. PPS is a relatively high-grade engineering plastics. Often used for special plastic products. Such as medical, automotive, and electronic industry.
PPS plastic material performance
1, The physical and mechanical properties of PPS is white. Crystalline high polymer density of 1.34. Excellent
mechanical properties, tensile strength. And bending strength than PA, PC, PBT, etc. With high rigidity and resistance
to creep. But brittle, low notched impact strength. Lower than PA, PC, PBT higher than POM. After
the addition of glass fiber reinforced its better mechanical properties. PPS case of inert material, non-toxic.
2, Since the thermal properties of the PPS polymer. Is a crystalline. The maximum degree of crystallinity of up to
65%. And a crystallization temperature of 127 ℃. A melting point of 286 ℃. Thermal deformation temperature
260 ℃. 430-460 ℃ in the air than before decomposition. Thermal stability far beyond the PA, PBT, POM, and other engineering plastics. Long-term use in thermoplastics highest temperature up to 220-240 ℃. PPS also has good thermal insulation and flame resistance. The critical oxygen index, and PVC equivalent of up to 47%. Without adding flame retardant.PPS can be achieved UL94-V0 grade level.
3, The molecular structure of the electrical properties of PPS symmetry, polarity, low water absorption. So it’s very
good electrical insulating properties compared with other engineering plastics, small dielectric constant.
Arc resistance equivalent to thermosetting plastics, high temperature, high under wet conditions such as frequency.
PPS can maintain good electrical insulating properties. Adding conductive fillers. Conductive PPS can be obtained as a composite material for the anti-static and electromagnetic shielding.
4, Since the chemical resistance of PPS, has a high degree of crystallinity. So it has excellent chemical resistance. Below 200 ℃ insoluble in any organic solvent. In addition to strong oxidizing acids. Maybe subjected to various types of acids, bases. Salts erosion at high temperatures after long-term immersion by a variety of chemicals, but also to maintain a high strength after PTFE. PPS also has good resistance to weathering resistance and radio.
