Available in rolls of unidirectional tape, as well as X-Ply™ 0˚/90˚ and other multi-ply laminates, Polystrand materials can be post-formed and co-molded with mixed materials in thermoforming and injection molding processes to achieve part designs and cycle times that meet the most demanding performance targets.

PCR content is recovered at the end of the product life cycle, collected and processed by local recycling facilities, rather than at the original polymer manufacturing site like PIR content. 

Until that number is zero, we have more work to do. Hydrocerol improved productivity up to 20% due to lower cycle times and processability on different injection molding units. In 2021, we anticipate formalizing and standardizing our approach to Life Cycle Analysis (LCA) and Product Carbon Footprint (PCF).

However, TPEs based on this technology can only be reliably used in two-shot over molding and very often do not work universally on different polyamides. These novel TPEs have no flow marks and showed fast cycle times, which are important commercial considerations.

Working with TPEs also gives you extensive design freedom, customization and color options. The most efficient way to discover whether TPEs could work for you, or which kind of TPE is best for you, is to speak with the experts directly.
