Introduction To INCHR@Conductive Masterbatch
Wide range of terminal applications: In the continuous evolution of materials science, conductive masterbatch, as an innovative functional material, is increasingly highlighting its key role in many fields. With its unique formula and preparation process, it gives plastic products excellent conductive properties, bringing new solutions to electronics, automobiles, packaging, and other industries.
Optional base resin types: Conductive masterbatch is based on pure resin, with high oil absorption value, ultra-fine particle size conductive filler as the conductive medium, and adding toughening agent, reinforcing agent, coupling agent, antioxidant and other additives, through specific processes such as internal mixer and twin-screw extrusion. As a professional manufacturer of conductive masterbatches, INCHR has an inventory for conductive masterbatches of the following base materials all year round: HIPS, LLDPE, HDPE, PP, PVC, ABS, POM, Nylon, etc. The masterbatch is suitable for injection molding, extrusion, film blowing, and other processing technologies.
Diversified formulations: The formula of conductive filler is also very diverse, including carbon black, carbon nanotubes, stainless steel fiber, etc. The filler ratio determines the resistance of the master batch and the amount. Among them, carbon black is favored in terms of conductivity due to its high cost-effectiveness.
Multiple Advantages Of INCHR@Conductive Masterbatch
- Improve conductivity: It can significantly give plastic products anti-static or electromagnetic shielding functions, meeting the strict requirements of electronic equipment for electrostatic protection and electromagnetic compatibility. For example, in the packaging of electronic components, packaging materials made of conductive masterbatch can effectively prevent static electricity from damaging precision components.
- Good dispersion uniformity: Effective dispersion in the matrix ensures that the conductivity of plastic products is uniform and stable, avoids performance problems caused by local conductivity differences, and improves the overall quality of the product.
- Excellent stability: A stable conductive network is formed in the resin, and the performance is long-lasting and stable during processing and use, ensuring long-term reliable operation of the product, and reducing maintenance costs and product failure rates.
- Cost control advantage: Compared with pure conductive materials, the reasonable addition of conductive masterbatch can reduce costs, making conductive plastic products more price competitive, which is conducive to large-scale production and application promotion.
- Excellent processing performance: It has little effect on the processing performance of plastics, and is easy to form through common processes such as injection molding and extrusion. There is no need to significantly change the existing processing equipment and processes, which improves production efficiency.
- Good compatibility: Based on a variety of matrices, it has good compatibility with various matrix resins and can be widely used in products of different plastic materials to expand the scope of application.
- Flexible and diverse design: The adjustable addition ratio provides more possibilities for product design, and can adjust the formula and performance according to different application requirements and product requirements to meet diverse market needs, such as the development of electromagnetic shielding materials with different shielding levels.
Standardize The Processing To Ensure Stable Quality
1·Pre-drying treatment
It is recommended to dry the conductive masterbatch before processing, especially hygroscopic materials such as carbon black conductive masterbatch, to avoid moisture affecting the processing performance and product quality.
2·Key points of the mixing process
Select masterbatches with good compatibility with the matrix resin, mix them evenly in a certain proportion, ensure that the conductive masterbatch is evenly dispersed in the matrix, and use high-speed mixers and other equipment to improve the mixing effect.
3·Processing technology adaptation
The mixed materials are processed into products through injection molding, extrusion, and other processes. According to different masterbatches and product requirements, the processing temperature, pressure, speed, and other parameters are accurately controlled to ensure the quality of product molding.
4·Precise control of dosage
Adjust the dosage of conductive masterbatch according to specific needs to achieve the ideal conductive effect. Too much or too little will affect the conductive performance, and the best addition ratio needs to be determined through experiments.
5·Finished product testing
After adding in strict accordance with the recommended ratio, the conductive performance of the finished product is tested to ensure that it meets the relevant standards and requirements. Professional resistance testing instruments can be used for testing.
6·Storage conditions
Avoid adverse environments such as humidity and high temperature during storage to prevent the masterbatch performance from deteriorating. It should be stored in a dry, cool, and ventilated place.
Carbon Nanotube(CNT) Enhancement Leads High-end Applications
Carbon nanotube-enhanced conductive masterbatch, such as 300CNT, a 100% multi-walled carbon nanotube conductive masterbatch and antistatic masterbatch, has emerged in the high-end field with its unique advantages.
- Only 2% addition can achieve antistatic performance, suitable for various occasions that require conductivity and antistatic performance. At the same addition ratio, its conductive effect far exceeds that of plastic masterbatch with added carbon black or carbon fiber.
- Adding more than 3 times the carbon black masterbatch can achieve the conductive performance of 300CNT.
This conductive masterbatch is suitable for injection molding and extrusion processes. For general engineering plastic resins such as ABS, PC, PS, PP, and PA6, the addition amount is usually 2%-8%, which can make the surface resistance of the product reach 10E+4 to 10E+9 ohms.
