Types of PPS Plastic
PPS resin comes in different forms, each with unique properties tailored for specific applications:
- Linear PPS: This type has nearly double the molecular weight of regular PPS, resulting in higher tenacity, elongation, and impact strength.
- Cured PPS: Produced by heating regular PPS in the presence of air, curing extends molecular chains and creates some branches, enhancing its molecular weight and providing thermoset-like characteristics.
- Branched PPS: With a higher molecular weight than regular PPS, this type features extended polymer chains branching off the backbone, improving mechanical properties, tenacity, and ductility.
Properties of Polyphenylene Sulfide (PPS)
Mechanical Properties
PPS plastic exhibits outstanding mechanical properties that make it ideal for various applications:
- Tensile Strength: With a tensile strength of 12,500 psi, this material can bear significant loads without breaking.
- Impact Resistance: Despite its rigidity, it has an Izod impact strength of 0.5 ft-lbs/in of notch, allowing it to withstand sudden shocks.
- Flexural Modulus of Elasticity: At 600,000 psi, PPS plastic can resist bending forces effectively, maintaining its shape and structural integrity.
- Dimensional Stability: PPS material maintains its dimensions even under high temperature and high humidity conditions, making it suitable for precision parts with tight tolerances
Thermal Properties
PPS excels in thermal stability and resistance, which are crucial for high-temperature applications:
- Heat Deflection Temperature: It can withstand temperatures up to 400°F at 66 psi and 200°F at 264 psi.
- Coefficient of Linear Thermal Expansion: It shows minimal dimensional changes with temperature variations at 4.0 in/in/°F x 10^-5.
- Maximum Continuous Service Temperature: You can use it continuously in the air at temperatures up to 338°F.
Chemical Resistance
PPS plastic is well-known for its exceptional chemical resistance.
- Insensitive to Moisture: It remains unaffected by moisture, ensuring durability and reliability in humid environments.
- Resistant to Chemicals: It withstands exposure to various chemicals, including acetone, benzene, chlorinated solvents, and sodium hydroxide, making it suitable for chemical processing applications.
Electrical Properties
PPS's electrical insulation properties make it suitable for electronic applications:
- High Volume Resistivity: It maintains high insulation resistance even in high-humidity environments.
- Dielectric Strength: It has a dielectric strength of 450 V/mil, ensuring excellent insulation.
Additional Properties
- Flame Resistance: Most PPS plastic compounds pass the UL94V-0 standard without additional flame retardants, making them suitable for fire-resistant applications.
- High Modulus: When reinforced, it exhibits a high modulus, enhancing its mechanical strength.
- Low Water Absorption: With water absorption of just 0.02%, it is ideal for applications requiring minimal moisture uptake.
- Injection molding
- Extrusion (film, fiber, sheet, shapes)
- Blow molding
APPLICATION
Polyphenylene sulfide (PPS) is a versatile thermoplastic that is used in a wide range of applications due to its exceptional properties. Some of the common uses of PPS include:
- Automotive parts: PPS is commonly used to make automotive parts such as engine components, fuel system parts, and electrical connectors.
- Electronics: PPS is used to make parts for electronic devices such as circuit boards, connectors, and switches.
- Aerospace: PPS is used in the aerospace industry to make components such as engine parts, electrical connectors, and insulation.
- Industrial applications: PPS is used in various industrial applications, such as chemical processing, oil and gas production, and power generation.
Packaging:
- Bags: 25 kg polyethylene or paper bags, moisture-proof and sturdy.
- Bulk Bags: 500 kg or 1000 kg bulk bags, moisture-resistant and durable.
- Sealed Containers: For maximum protection against moisture and contamination.
Transportation:
- Shipping Containers: 20-foot or 40-foot containers for international shipments.
- Truck Transport: Securely loaded trucks for domestic transportation.
- Rail Transport: Bulk bags or sealed containers loaded onto rail cars.
Handling Precautions:
- Avoid Moisture: Keep PPS resin dry to maintain quality.
- Secure Loading: Ensure bags and containers are fastened to prevent shifting.
- Temperature Control: Avoid extreme temperatures.
- Safe Handling: Use proper equipment to prevent spillage.
