For two-shot molding, the time between the first and second shots should be kept as short as possible to achieve the best bond. Overmolded parts will take longer to cool because the TPE is only cooled from one side as the plastic substrate has poor thermal conductivity.

Our discussions with legislators provide awareness on Avient’s role and contributions to the science that enables sustainability and a circular economy, as well as the importance of maintaining a cost and regulatory environment that allows companies to best operate, invest and grow. For every submission received, we pledged to donate to One Tree Planted.

Determining the best sustainable raw material for specific applications will depend on various factors including requirements related to color, performance, regulations, supply, and price.  If raw materials are sourced in one region but sold in another, they must follow the regulations of where they are sold.
