high-wear resistance engineering plastics PAI plate PAI4203 sheet
TORLON®PAI
The TORLON®PAI grades, is one kind of new acyl engineering plastic. Guangzhou Engineering Plastics Industries (Group) Company, has studied and applied this material in many industries for many years. As the molecules of TORLON®PAI, has a rather steady heterocyclic structure inside, which has the excellent performances of intrinsic high and low temperature resistance that other macromolecule materials can't compare with, and has excellent mechanical strength and dimensional stability resistance. Especially: high temperature resistance,high strength,high insulation,anti-radiation,chemical corrosion-resistance,self-lubrication and extremely low thermal expansion.
Main characteristics:
(PAI) (yellow-ochre)
TORLON® 4203PAI offers the best toughness and impact strength of all TORLON®PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, TORLON® 4203PAI is very popular for precision parts in high-tech equipment. In addition, its good electrical insulating ability provides numerous possibilities in the field of electrical components. Guangzhou Engineering Plastics Industries (Group) Company, can supply all the size of PAI4203 Sheets and rods, at the same time we also supply the PAI4203 Precision Parts.
TORLON®4301PAI
(PAI + graphite + PTFE) (black)
The addition of graphite and PTFE provides higher wear resistance and lower coefficient of friction compared to the unfilled grade as well as little or no stick-slip in use. This grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts. Guangzhou Engineering Plastics Industries (Group) Company, can supply all the size of PAI4301 Sheets and rods, at the same time we also supply the PAI4301 Precision Parts.
TORLON®5530PAI
(PAI-GF30) (black)
This 30% glass fiber reinforced grade offers higher stiffness, mechanical strength and creep resistance than TORLON® 4203PAI. It is well suited for structural applications supporting static loads for long periods of time at high temperatures. The suitability of TORLON® 5530PAI for sliding parts, however, is to be carefully examined since the glass fibers tend to abrade the mating surface. Guangzhou Engineering Plastics Industries (Group) Company, can supply all the size of PAI5530 Sheets and rods, at the same time we also supply the PA5530 Precision Parts.
PAI Sheet Size:500X1000X(Thickness:5-100mm),600X1200X(Thickness:5-100mm)
PAI Rod Size:Φ6-Φ150X1000mm

Main characteristics:
- very high max. allowable working temperature in air (250°C continuously)
- extremely low coefficient of linear thermal expansion up to 250°C
- excellent retention of mechanical strength, stiffness and creepage resistance over a wide range of temperatures.
- excellent wear and frictional behavior (particularly TORLON®4301PAI)
- exceptional resistance against high energy radiation(γradial and Χradial).
- inherent low flammability
