About RenJie® Conductive Masterbatch #### 1.1 Wide Range of End-Use Applications In the continuous evolution of materials science, conductive masterbatch — an innovative functional material — is playing an increasingly prominent role across many fields. With its unique formulation and preparation process, RenJie® conductive masterbatch gives plastic products excellent conductive properties, bringing new solutions to the **electronics, automotive and packaging** industries. #### 1.2 Optional Base Resin Types RenJie® conductive masterbatch is built on **pure resin**, using **high oil absorption value, ultra-fine particle size conductive filler** as the conductive medium, and is compounded with toughening agents, reinforcing agents, coupling agents, antioxidants and other additives through specific processes such as **internal mixing and twin-screw extrusion**. As a professional manufacturer of conductive masterbatch, RenJie® maintains year-round stock of conductive masterbatch in the following base materials: | Base resin | Full name | Compatible processes | | --- | --- | --- | | HIPS | High-impact polystyrene | Injection molding / extrusion / film blowing | | LLDPE | Linear low-density polyethylene | Injection molding / extrusion / film blowing | | HDPE | High-density polyethylene | Injection molding / extrusion / film blowing | | PP | Polypropylene | Injection molding / extrusion / film blowing | | PVC | Polyvinyl chloride | Injection molding / extrusion / film blowing | | ABS | Acrylonitrile-butadiene-styrene | Injection molding / extrusion / film blowing | | POM | Polyoxymethylene (acetal) | Injection molding / extrusion / film blowing | | Nylon | Polyamide (PA) | Injection molding / extrusion / film blowing | These masterbatches are suitable for **injection molding, extrusion, film blowing** and other processing technologies. #### 1.3 Diversified Formulations The conductive filler formulation is also highly diverse, covering **carbon black, carbon nanotubes, stainless steel fiber** and more. The filler ratio determines the resistance of the masterbatch and the required loading level. Among these, **carbon black** is favored for its **high cost-effectiveness** in conductivity. ### 2. Multiple Advantages of RenJie® Conductive Masterbatch | Advantage | What it delivers | Value to the customer | | --- | --- | --- | | Improved conductivity | Significantly imparts antistatic or electromagnetic shielding functions, meeting the strict requirements of electronic equipment for electrostatic protection and electromagnetic compatibility | For example, packaging made with conductive masterbatch for electronic components effectively prevents static electricity from damaging precision parts | | Good dispersion uniformity | Effective dispersion in the matrix ensures uniform, stable conductivity | Avoids performance problems caused by local conductivity differences and improves overall product quality | | Excellent stability | A stable conductive network forms in the resin, with long-lasting, stable performance during processing and use | Ensures long-term reliable operation, reducing maintenance costs and product failure rates | | Cost control advantage | Compared with pure conductive materials, reasonable addition of conductive masterbatch reduces costs | Makes conductive plastic products more price competitive, supporting large-scale production and adoption | | Excellent processing performance | Little effect on the processing performance of plastics; easy to form by common processes such as injection molding and extrusion | No need to significantly change existing processing equipment or processes, improving production efficiency | | Good compatibility | Developed on a variety of matrices, with good compatibility with various base resins | Widely usable in products of different plastic materials, expanding the scope of application | | Flexible and diverse design | Adjustable addition ratios give more possibilities for product design | Formulations and performance can be tailored to different applications, such as shielding materials with different shielding levels | ### 3.

Carbon Nanotube (CNT) Enhancement Leads High-End Applications Carbon nanotube-enhanced conductive masterbatch — such as **300CNT**, a **100% multi-walled carbon nanotube (MWCNT) conductive and antistatic masterbatch** — has emerged in the high-end field with its unique advantages: - Low loading, high efficiency: an addition of only 2% achieves antistatic performance, suitable for a wide range of occasions requiring conductivity and antistatic behavior; - Leading conductive performance: at the same addition ratio, its conductive effect far exceeds that of plastic masterbatch with added carbon black or carbon fiber. More than 3 times the amount of carbon black masterbatch is required to achieve the conductive performance of 300CNT; - Broad process and resin compatibility: suitable for injection molding and extrusion. For general engineering plastic resins such as ABS, PC, PS, PP and PA6, the addition amount is usually 2%–8%, bringing the surface resistance of the product to 10⁴–10⁹ Ω. ### 5. Frequently Asked Questions (FAQ) **Q1: What does conductive masterbatch do?** A: It imparts antistatic or electromagnetic shielding functions to plastic products, meeting the electrostatic protection and electromagnetic compatibility requirements of electronic equipment. In electronic component packaging, for example, packaging material made with conductive masterbatch effectively prevents static electricity from damaging precision parts. **Q2: Which base resins does RenJie® conductive masterbatch cover?** A: Year-round stock covers HIPS, LLDPE, HDPE, PP, PVC, ABS, POM and Nylon, all suitable for injection molding, extrusion and film blowing. **Q3: What loading of conductive masterbatch is required?** A: It depends on the target resistance and should be verified by testing. For 300CNT MWCNT masterbatch, 2% achieves antistatic performance, while general engineering plastics such as ABS, PC, PS, PP and PA6 typically use 2%–8%. **Q4: How do I choose between carbon black and carbon nanotube masterbatch?** A: Carbon black is cost-effective with good conductivity and is the most widely used filler, but it usually turns the part black and may reduce mechanical properties such as impact strength. Carbon nanotube masterbatch works at lower loading with better conductivity and less impact on the base resin, making it suitable for high-end applications and parts with strict appearance or mechanical requirements. **Q5: Does conductive masterbatch need pre-drying before processing?** A: Yes, pre-drying is recommended — especially for hygroscopic materials such as carbon black conductive masterbatch — to avoid moisture affecting processing performance and product quality. **Q6: How should conductive masterbatch be stored?** A: Store it in a dry, cool and ventilated place, away from moisture and high temperature, to prevent performance deterioration. | Product Description | Conductive ABS compound | | --- | --- | | RenJie®Grade | PS 0603C/PP C306/C401 | | Surface Resistivity | 0^2~10^5 Ohm/sq | | Volume Resistivity | 10^2~10^4 Ohm.cm | | Applying To | PP PS PE ABS PC Nylon PVC etc. | | Conductive filler | Carbon black /Carbon nanotube /Stainless steel fiber | | Processing | Injection/Extrusion/Blowing | | Applications | ESD packaging sheet, ESD packaging film | ### Related products [View all**](/en/products) [*709AN/747AN/920AN #### Antistatic ABS Compound RENJIE® antistatic ABS compound with 10^8–10^10 Ω surface resistance. 709A… View details*](/en/product/antistatic-abs-compound)[*757CF20/757CF30/757CF15 #### 15% Carbon fiber ABS RENJIE carbon fiber reinforced ABS is a high-performance thermoplastic com… View details*](/en/product/15-carbon-fiber-abs)[*70CF30/70CF20/70CF15 #### 30% Carbon Fiber Nylon 66 Explore Carbon Fiber Conductive Nylon properties, CFRTP Conductive Nylon g… View details*](/en/product/30-carbon-fiber-nylon-66) ### Request a quotation or sample We reply with price, MOQ and lead time within one business day. *Your name***Company Email***Phone / WhatsApp Country Product of interest Quantity Target price Application Message Send inquiry* We only use your details to reply to this inquiry.
