PPS GF30 For Gun Shell

Product Details

PPS GF30is the most widely used specialty engineering plastic and is known as the sixth largest engineering plastic. It has excellent heat resistance, chemical resistance, flame retardancy, mechanical properties, dimensional stability and processability. PPS also has shortcomings, PPS is brittle and has insufficient toughness.

Aerospace includes: gun housing, helmet, warship submarine corrosion-resistant wear parts, aircraft connectors, coil bobbin; automotive field includes: ignition system (ignition coil skeleton, transistor igniter housing, alternator carbon brush holder, fuse Housing), lighting system (bulb high pressure base, projection headlight cover), fuel system (fuel flow meter, fuel pump impeller, housing, throttle housing, carburetor coil bobbin), drive system (ABS system oil) Pressure piston, transmission hydraulic piston, solenoid valve housing), control system (sensor, ECU control unit housing, motor insulator, IPM, capacitor housing), cooling system (thermosterator housing, cooling water pump housing, impeller , supercharged tube).

PPSpolyphenylene sulfide has excellent heat resistance, its continuous use temperature is as high as 220-240 ° C, and the heat distortion temperature under the load of 1.82 MPa is above 260 ° C.

PPSpolyphenylene sulfide resin itself has good flame retardancy, UL94-VO and 5-V grade (no dripping) can be achieved without adding any flame retardant, and the amount of smoke during combustion is very low. PPS polyphenylene sulfide has excellent chemical resistance, second only to polytetrafluoroethylene, and is insoluble in any organic solvent below 200 ° C, except for strong oxidizing acids. And it is also very stable to various radiations.

The mechanical strength of pure PPS polyphenylene sulfide resin is not high. After being filled with glass fiber or carbon fiber or mineral, its strength and rigidity are doubled, and it has excellent creep resistance and fatigue resistance. After modification, a self-lubricating material with excellent wear properties can also be obtained. PPS polyphenylene sulfide resin has excellent molding shrinkage, low water absorption and low linear expansion, so it has excellent dimensional stability even under high temperature or high humidity conditions. PPS polyphenylene sulfide has good electrical insulation and dielectric strength, and does not change much even under high temperature, high humidity and high frequency conditions. PPS polyphenylene sulfide resin has good fluidity and can be formed by various methods. After fiber reinforcement or fillingPPS GF30, it can be injection molded into complex and thin-walled parts.
