PPS+GF40 For Battery terminal insulator

PPS+GF40Mechanical properties:

The mechanical properties of pure PPS are not high, especially the impact strength is relatively low. After being reinforced with glass fiber, the impact strength will be greatly improved from 27 J/m to 76 J/m, which is increased by 3 times; the tensile strength is increased from 6 Mpa to 137 Mpa, which is doubled. PPS is very rigid and rare in engineering plastics. The flexural modulus of pure PPS can reach 3.8Gpa, and the inorganic filler can reach 12.6Gpa and increase by 5 times. The PPO, which is known for its rigidity, is only 2.55 GPa, and the PC is only 2.1 GPa. PPS has good creep resistance under load and high hardness; its wear resistance is high, its wear at 1000 rpm is only 0.04g, and it will be further improved after filling F4 and molybdenum disulfide; PPS also has certain self Run. The mechanical properties of PPS are less sensitive to temperature.

PPS+GF40Thermal properties:

PPS has excellent thermal properties, can withstand 260 ° C in the short term, and can be used for a long time at 200 ~ 240 ° C; its heat resistance is comparable to PI, second only to F4 plastic, which is not in thermosetting plastics. More common.

PPS+GF40Electrical properties:

The electrical properties of PPS are very prominent. Compared with other engineering plastics, the dielectric constant and dielectric loss tangent are relatively low, and there is little change in the range of large frequency, temperature and temperature; PPS has good arc resistance and is comparable to thermoset plastics. PPS is commonly used in electrical insulation materials, and its dosage can account for about 30%.

PPS+GF40Chemical resistance:

One of the great characteristics of PPS is chemical corrosion resistance, its chemical stability is second only to F4; PPS is mostly acid, ester, ketone, aldehyde, phenol and aliphatic hydrocarbon, aromatic hydrocarbon, chlorinated hydrocarbon Stable, not resistant to chlorinated [3] benzene and oxidizing acids, oxidants, concentrated sulfuric acid, concentrated nitric acid, aqua regia, hydrogen peroxide and sodium hypochlorite. PPS has good radiation resistance.

PPS has good flame retardancy and its oxygen index is as high as 44%. Compared with other plastics, it is a high flame retardant material in plastics (pure PVC has an oxygen index of 47%, PSF of 30%, and PA66 of 29). %, MPPO is 28%, PC is 25%).

Glass fiber reinforced PPS engineering plastics application:

Pump casing, pump wheel, tile, gear, pulley, universal head, gasket, flange, counter, level, flow meter components, bearing cage, etc.
