MuCell Microcellular Foaming Solutions for Engineered Plastic Parts

Improved Quality & Lower Costs

Blow Molding Technology

As a leader in providing lightweighting solutions to the plastics injection molding industry, Trexel, Inc. has extended its MuCell processing solution to blow molded automotive components. In working closely with their OEM and Tier I customers, the company has recognized the need for lightweighting plastic parts beyond the traditional and proven injection molded interior, exterior and under the hood applications.

MuCell foamed automotive airduct, featuring significantly reduced material density

There are several highly desirable attributes of foamed versus solid blow molded parts:

- Weight savings

- The microcellular material structure improves thermal insulation and

- Improved acoustical properties

The MuCell technology, a physical foaming process, also has several advantages over the use of chemical foaming agents:

- No chemical reaction at narrow processing window

- No chemical additive residue in final parts

- MuCell foamed parts can be recycled in their original polymer designation; the process does not alter the chemistry of the polymer


  • "The new Golf VII is different: The Instrument Panel retainer is molded with the MuCell process, significantly reducing weight.  A welcome side effect: improved dimensional stability due to reduced residual stress in the part."

    "We have incorporated the MuCell processing technology into our manufacturing process for over 4 years now and that has allowed us to customize our designs to offer premium cushioning with a reduced amount of material. We have found the durability of these components exceeds standard foam running shoe applications – offering a longer wearing shoe with more rebound and energy return to our customers."
