Expandable Graphite GREP-EG

Special treated expandable graphite controlled expansion until 230°C

• High efficiency non-halogen flame retardant for several resins.
• High flame retardancy is achieved with lower loading level.
• Minimize deterioration of physical properties.
• Minimize smoke emission during burning.

• Knead at milder condition to prevent collapse of particle.
  Once collapsed, deteriorate flame retardancy.
• Perform powerful ventilation at vent of extruder.
• Do not use mesh at head of extruder.
