Avient’s team recommended the use of overmolding (two-shot injection molding) to integrate the boot with the saw housing, and trialed several products before customizing a grade from its portfolio. Avient gathered detailed data from this customer’s production facility in Mexico and helped them calculate and compare the costs of the two solutions. The TPE grade surpassed the performance of the previous material and allowed the manufacturer to introduce a more efficient production process.

COLOR AND EFFECTS Color Harmony If you are aiming for a homogeneous look, we can develop specific colorants so that different components of your appliance are the same color no matter which polymer types and grades they are made from. We offer a wide range of color concentrates for different polymer grades, from standard to engineering polymers, that fulfill the vertical burning (V-0; V-1; V-2) and horizontal burning (HB) tests. For added convenience, they can be combined with color but also with other additives, such as flame retardants, antistatic or laser marking additives, into a single combination masterbatch.
