High chemical resistance
It boasts remarkable chemical resistance, a consequence of its distinctive molecular makeup featuring rigid rings and sulphide bonds. This composition enables the material to effectively withstand various chemicals, such as acids, alkalis, and organic solvents.
Thermal stability
Owing to its unique molecular framework, which is composed of rigid aromatic rings and sulphide bonds, it demonstrates exceptional thermal stability. This configuration imparts significant intermolecular strength and superior thermal resistance, allowing the material to endure elevated temperatures without considerable degradation or compromised mechanical properties.
Mechanical strength
Key features of the mechanical strength of PPS include high tensile strength (50-100 MPa for unfilled grades), good bending strength (80-130 MPa for unfilled grades), moderate impact resistance, high hardness, excellent creep resistance and good fatigue strength.

Glass-filled polyphenylene sulfide is a remarkable material choice for high-performance applications, offering numerous advantages over its unfilled counterpart and other thermoplastics. Here's an extended overview of its benefits, drawbacks, applications, and comparisons with alternative materials:
Pros
Improved mechanical strength: It offers superior tensile strength, flexural strength and rigidity due to the reinforcing effects of glass fibres.
Improved dimensional stability: It keeps its shape and dimensions better under changing temperature and humidity conditions.
Improved wear resistance: The addition of glass fibres makes it more suitable for applications involving friction and abrasion.
Higher thermal properties: It has a higher heat deflection temperature (HDT) and better thermal conductivity than base PPS, making it ideal for high-temperature applications.
Cons
Low impact resistance: It may have lower impact resistance than basic PPS, due to the brittleness brought by the glass fibres.
Processing difficulties: It is more difficult to print than the unfilled variant, and may result in increased abrasion on tools and equipment during production.
Costs: It is generally more expensive than unfilled PPS due to the additional costs associated to glass fibres and processing.
Applications
Automotive parts: It is ideal for under-the-hood components requiring high strength and heat resistance, such as pumps, gears and valves.
Electronics: It is suitable for connectors, sockets and switches requiring excellent dimensional stability and high temperature resistance.
Industrial applications: It can be used in various industrial parts, including impellers, bearings and rollers, due to its superior mechanical properties and wear resistance.
Comparison
Unfilled PPS: It offers higher mechanical strength, better dimensional stability and greater wear resistance, making it a more robust solution for those applications where basic PPS might be insufficient.
Other thermoplastic materials (e.g., PEEK, PA, POM): PPS GF offers a balanced combination of chemical resistance, thermal stability and mechanical properties, making it a competitive option compared to those alternative materials.
In conclusion, it is a reliable, high-performance material that offers significant advantages over other thermoplastics, including unfilled PPS. The combination of outstanding properties and a wide range of applications makes it a valuable material for those seeking an effective and reliable solution for engineering needs.

Questions and answers
Glass-filled PPS GF is an advanced thermoplastic material based on Polyphenylene Sulfide (PPS), reinforced with a 25% glass fiber content. This material is known for its high mechanical strength, dimensional stability, hardness, and resistance to chemical agents, even in high humidity conditions. Thanks to its composition, PPS GF offers an extraordinary combination of rigidity and lightness, making it ideal for applications in harsh environments or those subjected to thermal and chemical stress. Its thermal stability allows it to operate at high temperatures without losing its mechanical properties, and the quality of the printed surface is suitable for high-precision technical applications.
Glass-filled PPS GF stands out for its excellent chemical and thermal resistance, which is superior to that of many other 3D printing materials. Unlike materials such as nylon or ABS, PPS GF maintains dimensional stability even in high humidity conditions or when exposed to aggressive chemical agents. Furthermore, thanks to the glass fiber reinforcement, it offers significantly greater rigidity and hardness compared to non-reinforced polymers, such as traditional PPS. This makes it particularly suitable for applications in demanding industrial environments where advanced mechanical properties and corrosion resistance are required.
The glass fiber, which constitutes 25% of the material, significantly enhances the mechanical properties and stability of PPS GF. It strengthens the polymer structure, increasing tensile strength, rigidity, and hardness. Additionally, the glass fiber reduces the coefficient of thermal expansion, improving the material’s dimensional stability even in humid environments or at high temperatures. This reinforcement makes it ideal for applications requiring precision, robustness, and durability.
Glass-filled PPS GF is widely used in technical and industrial applications due to its exceptional properties. In the naval industry, it is employed to produce components resistant to chemical agents and humidity. In the automotive and aerospace industries, it is chosen for structural and technical parts exposed to high thermal and mechanical stresses. Additionally, it is used in the electronics sector to create insulators and components requiring dimensional stability and chemical resistance. Thanks to its versatility, PPS GF is also used in the production of industrial equipment and functional parts for extreme environments, where resistance and precision are crucial.
