What is a TPE? What kind of stretch properties can I expect from my TPE? What is meant by hardness?

What is Recycled Content?

While the 2024 palette was mostly balanced with colors evenly distributed across the color spectrum, the 2025 palette predominantly features mid-tone blues, greens, oranges, neutrals, and no yellow,” said Roberto Romanin, Designer at ColorWorks Europe, Middle East, and Africa (EMEA) at Avient.

To enhance employee participation in our safety & health systems, the 2024 Annual Incentive Plan included a safety-based metric that measured the percentage of employees that participate in a safety engagement.

When showing constant dollar figures on GAAP and non-GAAP financial measures, the foreign exchange impact is calculated by using current foreign exchange rates and applying them to the prior period results.

SBCs are shear dependent – this means their viscosity is higher at low shear rates (such as extrusion) and lower at high shear rates (as in injection molding). SBC TPEs will flow more easily into thin areas of the mold at high shear rates. The figure below illustrates the effect of shear rate on the viscosity of GLS styrenic TPEs (measured at 390°F (200°C)).

Because it exhibits a higher flow rate than other SBC-based TPEs, OnFlex-S TPE reduces cycle times during injection molding, a feature that satisfies productivity objectives set by Jäger. A high melt flow rate for the solution reduces packing and cooling time requirements to improve overall molding cycle times. Faster processing = lower energy costs: Higher melt flow rates enable shorter injection molding cycles, resulting in reduced energy requirements.
