characteristics (1) general properties: PPS is a white, high crystallinity, hard and brittle polymer
The relative density of pure PPS is 1
3, but it will increase after modification
PPS has extremely low water absorption, generally only about 0
03%
PPS has good flame retardancy, and its oxygen index is more than 44%; Compared with other plastics, it is a high flame retardant material in plastics (oxygen index of pure PVC is 47%, PSF is 30%, PA66 is 29%, MPPO is 28%, PC is 25%)
(2) Mechanical properties: the mechanical properties of pure PPS are not high, especially the impact strength is relatively low
After reinforced with glass fiber, the impact strength will be greatly increased from 27j / m to 76j / m, which is increased by 3 times; The tensile strength increased from 6Mpa to 137mpa, doubled
PPS has high rigidity, which is rare in engineering plastics
The bending modulus of pure PPS can reach 3
8GPa and 12
6gpa after inorganic filling modification, which is as much as 5 times larger
PPO, which is famous for its rigidity, is only 2
55gpa and PC is only 2
1gpa
Good creep resistance under high creep load; The wear resistance is high, and the wear amount at 1000 revolutions is only 0
04g
It will be further improved after filling F4 and molybdenum disulfide; PPS also has certain self lubrication
The mechanical properties of PPS are less sensitive to temperature
(3) Thermal performance: PPS has excellent thermal performance
It can withstand 260 ℃ in a short time and can be used for a long time at 200 ~ 240 ℃; Its heat resistance is equivalent to PI, second only to F4 plastics, which is also rare in thermosetting plastics
(4) Electrical properties: PPS has outstanding electrical properties
Compared with other engineering plastics, its dielectric constant and dielectric loss tangent are relatively low, and it changes little in a large frequency, temperature and temperature range; PPS has good arc resistance, which is comparable to thermosetting plastics
PPS is commonly used in electrical insulation materials, and its dosage can account for about 30%
(5) Environmental performance: one of the biggest characteristics of PPS is good chemical corrosion resistance, and its chemical stability is second only to F4; PPS is stable to most acids, esters, ketones, aldehydes, phenols, aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons, and is not resistant to chlorinated biphenyls and oxidizing acids, oxidants, concentrated sulfuric acid, concentrated aqua regia, hydrogen peroxide and sodium hypochlorite
PPS has good radiation resistance
Application scope (1) Automotive Industry: PPS is used in the automotive industry, accounting for about 45%, mainly for automotive functional parts; For example, it can replace metal to make exhaust funnel, circulating valve, water pump impeller, pneumatic signal mediator, etc (2) Electronic and electrical appliances: PPS can account for 30% in the electronic and electrical appliance industry
It is suitable for high-temperature electrical components with ambient temperature higher than 200 ℃; It can manufacture point rinse, electric rinse bracket, starter coil, * cover and blade on generator and engine; On TV, it can be used for high voltage shell, socket, terminal post and terminal board; In the electronic industry, manufacture the framework and shell of transformer, choke and relay, and integrated circuit carrier; Using high-frequency performance, manufacture H-class winding frame and fine-tuning capacitor (3) Machinery industry: used for shell, structural parts, wear-resistant parts and sealing materials, including pump body, valve, bearing, bearing support, piston ring and gear, etc
