Overview
Hydrolysis-resistant weldable PPS (Polyphenylene Sulfide) is a high-performance thermoplastic known for its exceptional resistance to hydrolysis, making it ideal for applications in humid or wet environments. Its weldability allows for easy fabrication and assembly, expanding its utility in various industries. PPS is inherently stable at high temperatures and resistant to a wide range of chemicals, including acids, bases, and organic solvents. This combination of properties makes it a preferred material for demanding engineering applications.
Physical and Chemical Properties
Hydrolysis-resistant weldable PPS exhibits a high melting point (280-290°C) and excellent thermal stability, allowing it to perform reliably in high-temperature environments. Its density is approximately 1.35 g/cm³, and it is insoluble in most organic solvents. The material's hydrolysis resistance is a standout feature, ensuring long-term durability in moist or wet conditions. Additionally, its weldability facilitates the creation of strong, leak-proof joints, which is critical for components like fluid handling systems and electronic enclosures.
Main Applications
This material is widely used in the automotive industry for components such as fuel system parts, sensors, and connectors, where resistance to chemicals and high temperatures is essential. In electronics, it serves as a housing material for devices exposed to harsh environments. Industrial applications include pump components, valves, and seals, where hydrolysis resistance and weldability are crucial. The material's versatility also extends to aerospace and medical devices, where reliability under stress is paramount.
Safety and Storage
Hydrolysis-resistant weldable PPS is generally safe to handle, but precautions should be taken to avoid inhalation of dust and prolonged skin contact. Proper ventilation is recommended during processing to minimize exposure. Storage conditions should be dry and cool, away from moisture and direct sunlight, to maintain the material's properties. Bulk storage in sealed containers is advisable to prevent contamination and degradation.
B2B Procurement Guide
When procuring hydrolysis-resistant weldable PPS, it is essential to verify the material's specifications, including its hydrolysis resistance and welding compatibility. Suppliers should provide technical data sheets and certifications to ensure quality. Price ranges vary based on grade and supplier, typically between $5-$10 per kg. Bulk purchases may offer cost savings, but ensure the material meets your application requirements before committing to large quantities.
