The surface resistivity and volume resistivity are not sensitive to the changes of frequency, temperature and humidity;, PPS is an excellent electrical insulation material, which has a long arc resistance time and good chemical stability, except for strong oxidizing acids, such as concentrated sulfuric acid PTFE is not eroded by nitric acid and alkali, and most of it is nearly stable
Shoot below 175 The PPS is insoluble in any known organic solvent, and plastic cracking will not occur when PPS is in contact with general organic solvents
Chemical resistance: at present, no solvent that can dissolve polyphenylene sulfide below 200 ℃ has been found, and it has strong resistance to inorganic acids, bases and salts
No Resistant to chlorinated biphenyls and oxidizing acids, oxidants, aqua regia, hydrogen peroxide and sodium hypochlorite
The radiation resistance of PPS is good, and the radiation resistance reaches Gy 1 & times; 108 is a new material that can not be compared with other engineering plastics in electronics, electricity and machinery Machinery, instruments, aviation, aerospace and military, especially in the field of atomic bomb and neutron bullet, are the only ideal excellent materials for radiation resistance
The chemical structure of PPS itself is quite stable and contains flame retardant elements & mdash& mdash; Therefore, PPS has excellent flame resistance
Will try Ignite the tablet, adjust the flow rate of oxygen and nitrogen, and observe the combustion
The oxygen concentration that just keeps the test piece burning is the limit oxygen index, The higher the value, the better the flame resistance
The limiting oxygen index of pure PPS can be as high as 44, which has excellent flame resistance
Containing filler or glass PPS of fiber has higher limiting oxygen index and better flame resistance
Pure PPS can pass UL-94 grade V0 when the thickness is 0
8mm
Basically, except for a few grades such as super tough series, various grades of PPS The flammability of UL 94 belongs to V-0 level, which is the best level in UL 94 flammability
Super tough PPS series contains some toughening agents, which will sacrifice Animals have some flame resistance Pure PPS and PPS grades without conductive materials have excellent electrical insulation properties
The PPS grade with carbon fiber is quite low Product resistance coefficient Physical properties 1
Excellent electrical insulation (especially high-frequency insulation), white, hard and brittle, metallic sound when falling on the ground, and the light transmittance is second only to plexiglass, Coloring, water resistance and good chemical stability
It has excellent flame retardancy and is a non combustible plastic
2
The strength is general and the rigidity is very good, but the quality is brittle and easy to produce stress embrittlement; Not resistant to benzene, gasoline and other organic solvents; The long-term use temperature can reach 260 Degree, stable in air or nitrogen at 400 degrees
After modification by adding glass fiber or other reinforcing materials, the impact strength can be greatly The density is increased to 1
6-1
9, and the molding shrinkage is small to 0
15-0
25%; As heat-resistant parts, insulating parts, chemical instruments, optical instruments and other parts
Molding performance 1
Amorphous material has little moisture absorption, but it should be formed after drying
2
The fluidity is between ABS and PC, with fast solidification, small shrinkage and easy decomposition
Higher injection pressure and injection speed are selected
The mold temperature is 100 - 150 degrees
The taper of the main flow channel shall be large and the flow channel shall be short
The application scope can generally be used to manufacture PPS pipes, PPS plates and other materials, mostly in construction and home
