Industrial Expandable Graphite Feedstock

Description

1. Product Overview

Industrial Expandable Graphite Feedstock is a high-performance carbon-based material engineered for thermal expansion under high-temperature conditions. It is primarily used in flame-retardant systems, thermal insulation materials, sealing technologies, and advanced industrial composites. Upon exposure to heat, the material expands significantly, forming a protective intumescent barrier that enhances fire resistance and thermal stability.

This product delivers a strong balance of scalability, performance reliability, and industrial adaptability, making it a critical input for manufacturers seeking high-efficiency passive fire protection and thermal management solutions. Its strategic importance lies in its role as a core raw material for next-generation safety materials used across energy, construction, automotive, and petrochemical sectors.

2. Key Specifications & Technical Characteristics

• Material Composition: Natural graphite intercalation compounds (acid-treated graphite flake base)
• Active Content: High-carbon graphite (>95% carbon content typical feedstock grade)
• Expansion Ratio: 200–300 times expansion upon thermal activation (depending on grade)
• Particle Size: Customizable mesh sizes (commonly 50 mesh – 325 mesh)
• Form: Free-flowing powder / flake feedstock
• Color: Dark gray to black
• Bulk Density: Approximately 0.2–0.5 g/cm³ (before expansion)
• Packaging Options: 25 kg bags, 500 kg jumbo bags, bulk container shipment
• Shelf Life: 12–24 months under dry, sealed storage conditions

3. Core Industrial Applications

• Flame Retardant Systems: Used in intumescent coatings, fireproof boards, and cable protection materials
• Construction Industry: Applied in fire-resistant panels, doors, insulation foams, and structural coatings
• Energy & Petrochemical Sector: Thermal sealing in pipelines, tanks, and high-risk storage environments
