Expancel microspheres for thermoplastics

Find:

In thermoplastic processing, Expancel® Microspheres' uniform, closed cell structure results in a stable, controlled foaming process and is a phenomenal blowing agent on its own or combined with a chemical blowing agent.

Our Expancel®microspheres can be used in applications with process temperatures up to 235°C (455°F). It can be found in PVC, TPR, TPU, and rubber - across a wide range of thermoplastic applications. The advantages it delivers will help you achieve lighter products with higher quality in thermoplastics.

  • An easy flowing matrix enhances expansion capacity enabling low density even at low addition levels.
  • Low in density and weight with up to 40 times in volume compared to other materials.
  • Aesthetically appealing, matt rubber finish.

 

Expancel®DU and Expancel® DE are highly suited to help produce lightweight plastic automotive interiors and are used to reduce weight and dampen sound.

Our Expancel® DU products are used in the production of automotive weather strips for low weight and to improve sealing.

Expancel® DU and Expancel® MB allow you to produce low weight shoe soles and at the same time achieve a very important factor during the foaming process – control.

Thermoplastic processing methods with Expancel® Microspheres

No expensive equipment or licensing is necessary. Just add Expancel® microspheres.

  • Injection molding - add Expancel® microsphere to the mix and easily achieve density reduction levels between 10-30% in injection molding.
  • Extrusion - usable in almost every type of extrusion line, our microspheres help you reach perfect expansion in profiles, hoses, sheets, cables, and more.
  • Thermoforming - expanded microspheres withstand the thermoforming stage to give you a brilliantly foamed product. Both thin and thick sheets foamed with Expancel® microsphere leads to feasible thermoforming of e.g. PS and PP.
  • Blow molding - make foamed parts with blow molding processes but note that adjustments might be necessary on blow pressure to reach low densities.
  • Calendering - produce beautifully foamed sheets of e.g. PVC in calendaring processes.
