In contrast, the bio-derived grade offers greenhouse gas emissions at 2.35 kg CO2e / kg product, a nearly 25 percent lower cradle-to-gate product carbon footprint (PCF) than Avient’s standard Versaflex HC BT218 grade.

Relocate the gate to minimize the flow length to thickness ratio

Avient’s technical representatives worked with the tool maker to provide insight on venting, gate placement and other tool design concerns to minimize the potential for any tool-related problems.

By incorporating all the parameters (part design, tool layout, processing requirements, and material selection) there is an opportunity to proactively adjust the gate and runner location and size to ensure quality parts are consistently produced.  Ask your material supplier for more information about startup, processing temperatures, shutdown, drying, gate size, gate types, flow rates, purging, regrind, etc.

Our supply base currently includes 63 suppliers: 70% located in the UK, 17% in the EU and the remaining 13% split between China, USA and India.

The PA6 grade contains 76% PIR, and the PA66 grade contains 78% PIR content, resulting in up to 81% lower cradle-to-gate product carbon footprint (PCF) than traditional alternatives made without recycled content.

reSound™ Ultra-Low Carbon Footprint TPEs: These TPE formulations offer an industry-first cradle-to-gate negative, neutral, or near-zero product carbon footprint (PCF) while delivering comparable performance to traditional TPEs. 

Proper positioning of the gate, or mold opening, and proper mold design can minimize flaws. In the mold, use general purpose nozzles (not tapered nozzles) and large, free-flow gates. Runners should be designed with a full round gate and no sharp corners.1
