Features Of Addivant POYBOND 3200 Coupling Agent

  1. High-efficiency silane-based coupling agent specifically engineered for polyolefin–mineral filler systems.

  2. Enhances interfacial adhesion between hydrophobic polymers and hydrophilic inorganic fillers (e.g., calcium carbonate, talc, glass fibers).

  3. Improves mechanical properties including tensile strength, impact resistance, and flexural modulus in filled polypropylene and polyethylene compounds.

  4. Offers excellent thermal stability up to 300 °C, supporting high-temperature compounding and processing.

  5. Low volatility and non-corrosive formulation ensures safe handling and compatibility with standard extrusion and injection molding equipment.

Typical Applications Of Addivant POYBOND 3200 Coupling Agent

  1. Automotive interior and exterior components requiring high-stiffness, lightweight polyolefin composites.

  2. Packaging films and rigid containers where enhanced filler dispersion improves clarity and barrier performance.

  3. Household appliances with structural polypropylene parts containing high-load mineral fillers.

  4. Industrial pipes and profiles demanding long-term dimensional stability and creep resistance.

  5. Non-woven and spunbond applications using mineral-filled PP for improved fiber strength and processability.
