DURAFIDE PPS Japan Polyplastics 6565A7 flame retardant grade is a polyphenylene sulfide (PPS) product that is supplied from stock in original factory packaging.
Introduction of DURAFIDE PPS Polyplastics 6565A7 Original Packing Polyplastics/PPS:
The Chinese name of PPS plastic is polyphenylene sulfide, and the English name is Phenylene sulfide. It has the advantages of hard and brittle, high crystallinity, flame retardant, good thermal stability, high mechanical strength, and excellent electrical properties. PPS is one of the most heat-resistant varieties of engineering plastics. Its heat distortion temperature is generally greater than 260 degrees, its chemical resistance is second only to polytetrafluoroethylene, and its fluidity is second only to nylon. PPS plastic is a white, brown, high crystallinity, hard and brittle polymer. The relative density of pure PPS is 1.3, but it will increase after modification. PPS has a very small water absorption rate, generally only about 0.03%. 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 (the oxygen index of pure PVC is 47%, PSF is 30%, PA66 is 29%, 28% for MPPO and 25% for PC).
DURAFIDE PPS Japan Polyplastics 6565A7 original package/PPS Features:
The mechanical strength is particularly high, especially its bending strength value is very high, and it has excellent elastic recovery characteristics.
Has high toughness, compressive properties and shear properties values.
It still has excellent creep resistance under high temperature and high load, and it also shows excellent fatigue resistance for cyclic stress.
High elongation and impact strength, greatly improved the brittleness of the previous PPS resin, which was considered a disadvantage.
Can withstand 260 ℃, 10 seconds of immersion in the electric soldering bath, enough to meet the requirements of the surface assembly technology of electronic components.
There are very few ionic impurities, and it may also be used in fields with very strict requirements on electrical properties.
The volume resistivity changes very little under high humidity and high temperature conditions, and the dielectric constant hardly changes with the cycle number and temperature. It has very good properties as an electrical insulating material.
The fusion strength is high, and the secondary processing characteristics such as tapping and pressing are excellent.
PPS was first industrialized by the American Phillips Company in 1971. After the patent expired, Japanese companies also began to develop and produce it. The world’s top five PPS manufacturers are Phillips, Toray, Ticona, Polyplastics and Nippon Dai Ink.
DURAFIDE PPS Polyplastics 6565A7 original package Polyplastics/PPS Application fields:
Nylon is used in various fields of machinery industry (PA), polyoxymethylene (POM), polyethylene terephthalate (PET) and polysulfone (PSU) all have defects that cannot meet the technical requirements, while polyimide (PI) polyetheretherketone (PEEK) is used ) and polyamide-imide (PAI) are too expensive, choosing to use PPS should be an ideal engineering plastic.
