EVEC-Engineered Polyurethane Foam

PAKCOOL®

    基本性能:

  • Polyurethane porous structure for noise reduction, significantly weakens cavity noise.

  • Special formula and chemical rubber mixing process provide high viscoelasticity.

  • High bonding performance and excellent weather resistance.

  • Excellent stress buffering performance, acoustic foam does not crack.

  • Aging-resistant with strong stability.

  • Suitable for both new and used tires, with strong compatibility.

    应用:

  • Can be used by tire manufacturers to upgrade OE inner tire noise-reducing products; also applicable for retrofitting cleaned used tire inner walls.
