As a leading plastic material supplier based in Shanghai, China, Shanghai Yunshan Plasticizing Co., Ltd. is proud to introduce our premium PPO PX1600X-701 – a high-performance, high heat resistance Polyphenylene Oxide (PPO) compound engineered specifically for demanding industrial applications, particularly industrial electrical connectors. Our extensive experience in the plastics industry allows us to understand the critical need for materials that can withstand harsh operating environments while maintaining precision and reliability. This grade represents our commitment to providing solutions that enhance product longevity and performance in critical industrial components.
Industrial connectors are the lifelines of modern machinery and electrical systems, often exposed to elevated temperatures, mechanical stress, and challenging chemical conditions. Standard plastics can fail under such stress, leading to downtime and safety risks. Our PPO PX1600X-701 is formulated to address these exact challenges. It offers an exceptional balance of thermal, mechanical, and electrical properties, making it a superior choice for manufacturers seeking to upgrade their connector designs.
This data sheet provides a comprehensive overview of the PX1600X-701 material, detailing its key characteristics, processing guidelines, and the tangible benefits it delivers to your production process and final product.
Core Product Features & Technical Advantages:
Outstanding Thermal Performance: The defining feature of PX1600X-701 is its high heat deflection temperature (HDT), typically exceeding 160°C (320°F) under load. This allows connectors to maintain structural integrity and dimensional stability in high-temperature environments common in industrial controls, automotive under-hood applications, and power distribution systems.
Superior Dimensional Stability: PPO exhibits very low moisture absorption and minimal creep under load. This results in connectors that retain their precise shape and mating tolerances over time and across varying humidity conditions, ensuring consistent electrical contact and preventing connection failures.
Excellent Electrical Properties: This material maintains stable dielectric strength and volume resistivity over a wide temperature range. It is an excellent electrical insulator, which is fundamental for connector housings to prevent short circuits and ensure signal integrity.
High Mechanical Strength & Stiffness: PX1600X-701 provides high tensile strength and flexural modulus, offering robust protection for the internal metal terminals against physical impact, vibration, and insertion/withdrawal forces.
Good Chemical Resistance: It demonstrates good resistance to a broad range of chemicals, including acids, bases, detergents, and hydrocarbons, protecting the connector from degradation in harsh industrial or automotive environments.
Flame Retardancy (Optional): While the base material offers inherent resistance, flame-retardant grades compliant with various industry standards (e.g., UL 94) can be supplied upon request to meet specific safety requirements.
Ease of Processing: Despite its high-performance nature, this modified PPO grade is designed for good flow characteristics during injection molding, allowing for the production of complex, thin-walled connector geometries with high precision and yield.
Typical Physical & Mechanical Properties (Representative Values):

| Melt Flow Rate (300°C/5kg) | ISO 1133 | g/10 min | 12 - 18 |
| Tensile Strength (Yield) | ISO 527 | MPa | 65 |
| Flexural Modulus | ISO 178 | MPa | 2500 |
| Heat Deflection Temp. (1.8 MPa) | ISO 75-1/A | °C | 160 |
| Dielectric Strength | IEC 60243-1 | kV/mm | 22 |
| Comparative Tracking Index (CTI) | IEC 60112 | - | PLC 2 (275V) |
Processing Guidelines for Injection Molding:
Drying: Material must be thoroughly dried before processing. Recommended conditions: 3-4 hours at 100-120°C. Moisture content should be below 0.02%.
Melt Temperature: 260°C - 300°C (500°F - 572°F). Optimal range is typically 280°C - 290°C.
Mold Temperature: 80°C - 120°C (176°F - 248°F). Higher mold temperatures improve surface finish and reduce molded-in stress.
Injection Speed & Pressure: Use moderate to high injection speeds. Adequate holding pressure is necessary to compensate for shrinkage and ensure dimensional accuracy.
Benefits for Your Business:
Enhanced Product Reliability: Connectors made from PX1600X-701 are less likely to warp, crack, or lose insulating properties in high-heat conditions, leading to fewer field failures and higher customer satisfaction.
Design Freedom: The combination of high flow and good thermal stability allows for the design of more compact, complex, and miniaturized connectors without sacrificing performance.
Cost-Effective Production: Good processability translates to shorter cycle times, lower reject rates, and higher overall manufacturing efficiency.
Compliance with Industry Demands: This material helps your products meet the rigorous performance standards expected in automotive, industrial automation, and electrical equipment sectors.
Frequently Asked Questions (FAQ):
Q1: What is the maximum continuous use temperature for PPO PX1600X-701?
A1: While the Heat Deflection Temperature is 160°C under load, the material can typically be used continuously in environments up to 110-120°C, depending on the specific mechanical and electrical requirements of the application.
Q2: Is this material suitable for outdoor applications?
A2: Yes, PPO has inherent resistance to hydrolysis and UV degradation. However, for prolonged outdoor exposure, especially in direct sunlight, UV-stabilized grades or additional protective measures are recommended for optimal long-term performance.
Q3: Can PX1600X-701 be used for food-contact or medical applications?
A3: No. The standard PX1600X-701 grade is formulated for industrial electrical applications. It is not certified for food contact or medical use. Specialized, compliant grades would be required for those markets.
Q4: How does it compare to PBT or Nylon for connectors?
A4: Compared to PBT and Nylon, PPO generally offers superior dimensional stability (lower moisture absorption), higher heat resistance, and better hydrolytic stability. It may have a higher material cost but provides enhanced performance in critical areas.
Q5: What colors are available?
A5: The natural color is typically a beige or off-white. Custom colors can be produced upon request, subject to minimum order quantities.
Q6: Do you provide material samples for testing?
A6: Yes, Shanghai Yunshan Plasticizing Co., Ltd. can provide small material samples for customer evaluation and mold trials. Please contact our sales team to arrange a sample request.
Q7: What is the lead time for an order?
A7: Lead times vary based on order quantity and customization. Standard grades are typically available from stock or with short lead times. Our team in Shanghai will provide a precise timeline upon receipt of your inquiry.
