Nylon Innovation: COC Blending Technology, Reshaping New Heights of Material Performance

In the continuous exploration of materials science, COC new materials with its excellent performance characteristics, for nylon (PA) material innovation has injected new vitality. COC, or cyclic olefin copolymer, with its high strength, high rigidity, high temperature resistance qualities, and PA material blending, to achieve the double enhancement of the rigidity and heat resistance, for the application of engineering plastics to open up new horizons.

COC/PA composites: melt blending, performance leap

By melt blending polyamide with COC, we have obtained a new type of polymer composite material, which has achieved significant improvement in heat resistance and rigidity. This COC/PA composite preparation method is not only easy to process, but also excellent, bringing new breakthroughs in the field of materials science.

Mechanical properties and application limitations of nylon

Nylon is widely used in transmission components for its excellent mechanical properties, high mechanical strength and good toughness, and its self-wetting and friction resistance allow for extended service life.PA6 and PA66, as the dominant products in the market, are particularly widely used in structural and stressed components. However, in order to meet the demands of applications in high-temperature environments, it is often necessary to enhance temperature resistance by adding glass fibers, which not only increases the specific gravity of the material, but also affects the appearance of the product and the range of applications.

Optical properties and dimensional stability of COC

With its amorphous transparency and cyclic olefin structure, COC material is not only comparable to PMMA in terms of optical properties, but also shows more excellent dimensional stability with its higher heat resistance than PC and low water absorption. This makes COC an ideal choice for enhancing the performance of PA materials.

Preparation process of COC/PA composites

By mixing PA6, COC, toughening agent, compatibilizer and silicone powder, and then adding them into a twin-screw extruder, COC/PA composites with excellent performance are produced through mixing, extruding and pelletizing at a controlled temperature of 240-270°C. The same method is also applied to PA6, COC, compatibilizer and silicone powder. The same method is also applicable to PA66, which only requires temperature control in the range of 240～260℃.

Compatibility and reinforcement of COC and PA

With the assistance of the compatibilizer, the compatibility problem between COC and PA is solved. The cyclic structure of COC is embedded in the polyamide chain segment, which effectively improves the rigidity and heat resistance of the material. The injection-molded samples reached ISO standards in key mechanical properties such as tensile strength, flexural modulus and impact strength, achieving a significant improvement in the performance of PA materials.

Conclusion:

The successful development of COC/PA composites not only brings new possibilities for the application of nylon materials, but also provides a new direction for the development of materials science. The innovation of this material predicts that we will usher in more technological breakthroughs and application expansion in the field of high-performance engineering plastics.
