What does PPS plastic stand for?
Polyphenylene sulfide
Polyphenylene sulfide (PPS) is a partially crystalline, high temperature performance polymer that has the chemical structure shown in the figure on the right. This polymer has a high melting point of approximately 280°C, excellent chemical resistance and is inherently flame retardant.
How strong is PPS plastic?
PPS Properties
| UNITS | PPS | |
|---|---|---|
| Tensile strength | psi | 12,500 |
| Flexural modulus | psi | 600,000 |
| Izod impact (notched) | ft-lbs/in of notch | 0.5 |
| Heat deflection temperature @ 264 psi | °F | 220 |
Is PPS hygroscopic?
PPS products are not hygroscopic, and therefore, do not experience dimensional expansion problems like nylon (polyamides). Yet it is important to use dry resin in molding parts. PPS should be dried in dehumidifying hopper dryers.
Is PPS amorphous or crystalline?
Polyphenylene sulfide (PPS) is a semi-crystalline engineering thermoplastic recognized for its unique combination of properties including chemical resistance, dimensional stability and thermal stability.
Is PPS toxic?
Environmental precautions: PPS resin is a stable organic thermoplastic and a hazardous polymerization will not occur.
Is PPS hydrophobic?
The hydrophobic PPS block is converted into hydrophilic poly(propylene sulfoxide) and poly(propylene sulfone) by oxidation upon exposure to 1% aqueous H2O2 subphase. By contrast, vesicles can potentially rearrange molecules in their bilayers to accommodate a changing hydrophilic-lipophilic balance (HLB).
Is PPS brittle?
PPS has high strength, high rigidity and low degradation characteristics even in high temperature conditions. PPS has however, a lower elongation to break, a higher cost and is rather brittle.
Is PPS safe?
1. Material safety and hygiene: PPS chopsticks have passed the national food-grade health safety test. 2. Non-adhesive, more durable: because the surface of the chopsticks is not adsorbed, so the chopsticks are not easily eroded and become old (the chopsticks will be brighter and brighter after a long time).
What is PPS capacitor?
Typical Applications SMD Film capacitor using a stacked and naked construction with metallized polyphenylene sulfide (PPS). Available in case sizes from 1206 to 1812 and capacitance values from 1 nF up to 180 nF. PPS film capacitors provides very stable capacitance value with temperature, similary to ceramic NPO.
What is the full form of PPS?

| Prospective Payment System | Healthcare | PPS |
| Protocol and Parameter Selection | Networking | PPS |
| Power Point Show | File Type | PPS |
What is PPS Fibre?
Polyphenylene sulfide fibers (PPS) are high-performance, semi-crystalline fibers with exceptional chemical and heat resistance, high dimensional stability, low moisture absorption, and high resistance to hydrolysis when exposed to acids, alkalines, and organic solvents.

What are the mechanical properties of PPS plastic?
Mechanical Properties PPS has high strength, high rigidity and low degradation characteristics even in high temperature conditions. It also shows excellent fatigue endurance and creep resistance. PPS has however, a lower elongation to break, a higher cost and is rather brittle.
What kind of material can PPS be filled with?
PPS resin is generally reinforced with various reinforcing materials or blended with other thermoplastics in order to further improve its mechanical and thermal properties. PPS is more used when filled with glass fiber, carbon fiber, and PTFE. Many grades are available including:
When to use Polyphenylene sulfide ( PPS ) resin?
PPS resins (base polymer, glass-reinforced, and mineral/glass-reinforced systems) are typically used for injection molding, extrusion blow molding, and extrusion applications. Polyphenylene Sulfide can be processed at temperatures in the range of 300 to 350°C.
What makes Polyphenylene sulfide a high performance plastic?
Polyphenylene sulfide (PPS) is a high-performance, engineering thermoplastic characterized by an unusual combination of properties. These properties range from high temperature performance to dimensional stability and excellent electrical insulation properties. But, what makes PPS a high performance plastic in several sectors?
