Ericw Ew 250g 1: 1 Replacement Core Pigment Timcal Ensaco 250g-High-Structure Low-Viscosity Conductive Carbon Black Pigment

Product Description

Product Description

1. Product Basic Information

TIMCAL ENSACO™ 250G is a high-performance conductive carbon black under TIMCAL's ENSACO™ series, categorized as a polymer additive/filler and engineering material. It features high to very high void volume, enabling stable carbon network formation even at low filler content. With high structure, low surface area, soft flake form and low oxygen content, it excels in electrical conductivity, dispersion and processability, making it suitable for rubber (including silicones and fluoroelastomers) and polymer applications.

2. Product Features

• Excellent Conductivity & Processability: Maintains conductive network at low filler content; soft flakes ensure easy mixing/processing, with low viscosity increase and no cure inhibition.
• Ultra-High Purity: Ash content as low as 0.010% and sulfur content ≤0.020%, meeting stringent purity requirements for high-end applications.
• Balanced Mechanical & Rheological Properties: Enhances material conductivity without compromising mechanical performance (e.g., tensile strength, elongation at break) in rubber/polymers.
• Wide Rubber Compatibility: Suitable for all rubber types (silicones, fluoroelastomers, NBR, CR, EVA/NBR), adapting to diverse automotive and industrial rubber part needs.

3. Product Applications

• Automotive Rubber Components: Used in fuel hoses, transmission belts and conveyor belts, providing antistatic/conductive protection and reinforcing mechanical strength.
• Conductive Profiles & Seals: Ideal for power cable accessories, conductive profiles and seals, ensuring stable electrical performance and environmental resistance.
• Antistatic Flooring & Rollers: Applied in antistatic flooring and roller coverings, preventing electrostatic accumulation and ensuring safe operation.
