Dow ENGAGE 8480 Impact Modifier

ENGAGE™ 8480 is an ethylene-octene copolymer polyolefin elastomer from Dow, excelling in footwear, tubing and hose profile extrusion. It offers good clarity, toughness, flexibility, and excellent compatibility with other polyolefins for efficient blending and coextrusion.

Features Of Dow ENGAGE 8480 Impact Modifier

  1. Supplied in pellet form, enabling automated feeding and precise dosing for continuous production

  2. Balances high clarity and flexibility, meeting dual requirements for appearance and touch in footwear and hoses

  3. Excellent compatibility with polyolefins, allowing efficient blending with PE, PP, etc., to expand material performance

  4. High tear strength and impact resistance, enhancing product durability and damage tolerance

  5. Wide temperature tolerance, maintaining stable mechanical properties between -31°C and 99°C

Typical Applications Of Dow ENGAGE 8480 Impact Modifier

  1. Footwear applications, including sneaker midsoles, upper elastic strips, and anti-slip soles, providing rebound and comfort

  2. Tubing and profile extrusion, such as food-grade hoses, medical catheters, and industrial delivery pipes, balancing clarity and flexibility

  3. Cross-linked foam products, like cushioning pads, sound insulation cotton, and shoe foam layers, improving light weight and shock absorption

  4. Polyolefin blending modification, enhancing low-temperature toughness and impact resistance of PP/PE for automotive interiors and home appliance parts

  5. Wire and cable outer sheaths, ensuring safety in outdoor and complex environments with weather resistance and insulation
