As a specialized manufacturer of high-performance engineering plastics, Shanghai Yunshan Plasticizing Co., Ltd. proudly presents our POM CE66 High-Flow Copolymer, a material engineered to solve the challenges of molding intricate and demanding components. Based in the industrial hub of Shanghai, we combine advanced polymer technology with a deep understanding of manufacturing needs to deliver materials that enhance productivity and part quality. This specific grade is developed to offer exceptional flow characteristics, enabling the successful production of complex geometries, thin walls, and detailed features that are often problematic with standard materials.
Core Advantages and Technical Specifications:
POM CE66 stands out in the crowded field of engineering thermoplastics due to its balanced property profile tailored for precision injection molding. Its high flowability reduces injection pressure and allows filling at lower temperatures, which directly translates to several key benefits for manufacturers.
Enhanced Moldability: Achieve complete filling of complex molds with long flow paths, minimizing short shots and improving yield rates.
Reduced Internal Stresses: Lower processing pressures and temperatures help decrease molded-in stresses, leading to parts with better dimensional stability and reduced warpage.
Energy Efficiency: The ability to process at lower temperatures can contribute to lower energy consumption during production.
Excellent Surface Finish: The material flows smoothly into fine mold details, resulting in parts with a superior surface appearance right out of the mold.
Detailed Property Profile:
Beyond its flow, POM CE66 retains the classic desirable properties of POM copolymer, making it suitable for functional, high-performance parts.
| Property | Typical Value | Test Standard | Benefit to Customer |
|---|---|---|---|
| Melt Flow Rate (MFR) | High (Specific value available upon request) | ISO 1133 | Quantifies superior flow for complex molds |
| Tensile Strength | Excellent | ISO 527 | Provides high mechanical strength for durable parts |
| Impact Resistance | Good | ISO 179 | Offers toughness for applications subject to shock or load |
| Coefficient of Friction | Low | Customizable | Ideal for gears, bearings, and sliding components |
| Continuous Use Temperature | Up to approx. 100°C | - | Suitable for under-hood automotive or warm environment applications |
| Chemical Resistance | Very Good | - | Resists fuels, solvents, and many chemicals |
Target Applications and Industry Solutions:
Precision Gears and Cams: Its low friction and wear, combined with high stiffness and flow for intricate tooth profiles.
Automotive Components: Fuel system parts, door lock mechanisms, seat belt components, and intricate clips requiring chemical resistance and precision.
Consumer Electronics: Housings with snap-fits, hinges, and internal mechanisms demanding a fine finish and dimensional accuracy.
Industrial Parts: Valve bodies, pump components, and conveyor system parts where complexity and durability are critical.
Processing Guidelines:
To fully leverage the benefits of POM CE66, we recommend the following general processing parameters. Optimal settings may vary based on part design and machine.
Drying: Recommended before processing (2-3 hours at 80-90°C) to ensure optimal surface quality.
Melt Temperature: 190-210°C
Mold Temperature: 60-90°C
Injection Speed: Medium to High to utilize the high-flow characteristic.

Frequently Asked Questions (FAQ)
Q1: What makes POM CE66 "high-flow" compared to standard POM copolymer?
A: The "high-flow" designation refers to a specifically engineered polymer structure that results in a higher Melt Flow Rate (MFR). This means it has lower viscosity in the molten state, allowing it to fill complex and thin-walled molds more easily under standard injection pressures.
Q2: Does the high-flow property compromise the mechanical strength or thermal stability of the material?
A: No, POM CE66 is formulated to maintain the core mechanical properties—such as tensile strength, stiffness, and creep resistance—that POM is known for, while enhancing flow. Its thermal stability remains suitable for typical POM application environments.
Q3: Is this material suitable for food contact or medical applications?
A: The standard POM CE66 grade is not specifically certified for food contact or medical use. For such regulated applications, special grades with relevant certifications may be available upon request. Always verify compliance with your specific regional regulations.
Q4: Can POM CE66 be colored?
A: Yes, it can be compounded with a wide range of color masterbatches. For consistent and precise colors, we recommend using masterbatches compatible with POM and consulting with our technical team for specific recommendations.
Q5: What are the key considerations for drying this material before processing?
A: Although POM is not highly hygroscopic, drying is recommended to prevent potential surface defects like splay marks. We suggest drying at 80-90°C for 2-3 hours in a dehumidifying hopper dryer. Proper drying ensures optimal surface finish and mechanical properties.
Q6: How does POM CE66 perform in terms of wear and friction?
A: It inherits the excellent low friction and high wear resistance characteristic of POM copolymers. This makes it an outstanding choice for moving parts like gears, bearings, sliders, and cam mechanisms without the need for external lubrication in many cases.
Q7: Are there any specific mold design recommendations for using this high-flow grade?
A: While it fills molds more easily, standard good practices for crystalline materials like POM still apply. Adequate venting is important due to the potential for rapid filling. The high flow can allow for longer flow lengths or thinner walls, but part and mold design should be reviewed with material flow simulations for optimal results.
Q8: Do you provide technical support for trial runs or processing troubleshooting?
A: Yes, our technical support team, based on our experience in Shanghai and serving various industries, can provide guidance on processing parameters, troubleshooting common molding issues (like warpage or voids), and help with the initial trial runs to ensure a successful implementation.
