Description
Technical field
The present invention relates to plastics arts, specially a kind of low-k PPS.
Background technique
PPS plastics (polyphenylene sulfide) are a kind of thermoplastic special engineering plastics of excellent combination property, the feature protruded
It is high temperature resistant, corrosion-resistant and superior mechanical performance.PPS is sulfur-containing aromatic polymers, and line style PPS is crosslinked at 350 DEG C or more
Afterwards at thermosetting plastics, branched chain type structure PPS is thermoplastic.Pps is a kind of white powder, average molecular weight 0.4-
0.5 ten thousand, density is 1.3-1.8 grams per cubic centimeter, and pps has very excellent hot property.Heat after adding glass fiber reinforcement
Performance indicator is higher, and at 232 degrees Celsius after the heat ageing of 5000h, such as glass fibre, carbon fiber, filler enhance its power
Performance is learned, modified pps can keep high mechanical property and dimensionally stable under the action of long-term work load and thermic load
Property, thus can be applied in the high force environment of temperature.The dielectric constant very little of pps, dielectric loss is at a fairly low, surface resistivity
It is insensitive with variation of the volume resistivity to frequency, temperature, humidity, it is excellent electrically insulating material, its resistance to arc duration
Longer, the chemical stability of pps is fairly good, in addition to by Strong oxdiative acid, as the concentrated sulfuric acid, concentrated nitric acid and chloroazotic acid erosion outside, it is not
By the erosion of most acid-alkali salts, there is the chemical stability close to PTFE.When being lower than 175 degrees Celsius insoluble in any
Known organic solvent, pps and common organic solvents are not in plastic cracking phenomena when contacting.
Due to Development of Communication demand, development from from 4G to the higher frequencies section such as 5G and 10G, and also corresponding part is increasingly
Small, due to the requirement of automation, the plastic medium of welding allows for the welding temperature of 260 degree of tolerance, thus develops low
