The automated pultrusion process fabricates continuous glass or carbon fiber-reinforced, constant cross-section profiles with consistent, uniform properties.  For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating. The third profile was also 41% lighter than aluminum, with a 50% increase in flexural stiffness, and maintained torsional rigidity slightly better than that of aluminum.

For styrenic-based TPEs, the gate depth (D) should be 25-35% of the TPE component’s wall thickness at the gate entrance; 35-50% for urethane-based TPEs. Machines with programmable injection rates to “profile” the shot, and independent first and second stage pressures can produce better quality parts.

Explore the design options & challenges of TPEs with sustainable content TPEs can incorporate sustainable content in two ways: using either recycled or bio-based content in the formulations. Uncolored TPEs are naturally dark (typically in gray or brown), based on assorted colors from recycle streams 

Nymax BIO formulations can be both injection molded and extruded, making them suitable for automotive, consumer, industry, and building and construction applications. Bio-Derived TPEs: reSound™ BIO

Examples of custom formulations that help achieve a more sustainable product profile are a nucleating agent combined with color in a ready-to-use formulation or a desired color offered in a bio-polymer based ready-to-use product.
