First, the characteristics:
1、High strength, high toughness, high creep resistance, high torque: applicable to pipe fittings, joints, valve bodies, etc. with some internal threads for support and protection.
2、High temperature resistance, hydrolysis resistance, UV resistance: medical equipment and parts suitable for high temperature cooking and ultraviolet sterilization.
3、Small specific gravity and simple molding: because the PPS has a small specific gravity, the injection molding method is simple and efficient, and can replace metal materials such as aluminum alloy, copper alloy, and stainless steel, which can greatly reduce product cost, improve work efficiency, and save processing cost.
4 、 Self-flame retardant: it has its own flame retardant V0 grade, no need to add any flame retardant, and self-extinguishing from the fire. Can produce piping systems with flame retardant or fire protection requirements
Second, the application examples:
Thermostatic valve, Solar water mixing valve, Hardware sanitary ware, Faucet, Car water room, etc.
Third, PPS and PPSU performance comparison:
Melt flow rate
Elongation at Break
Izod Impact, Notched
Heat Deflection Temperature
Volume Resistivity ×1015
Dielectric strength 1MHz
As can be seen from the above table, PPS has:
Better dimensional stability: lower deformation of parts under alternating hot and cold conditions
Lower water absorption: the lower the water absorption rate, the longer the product aging time Higher strength and modulus: stronger support and protection
Higher temperature resistance: better heat aging performance
In addition, PPS has better process ability, lower processing energy and lower material costs.
