Those depicted may not be an exact match for your requirements, but when Avient color experts learn how a color will be used and what materials are involved, they can suggest an appropriate pigment for your specific applications. www.avient.com Copyright © 2020, Avient Corporation. Processing conditions can cause material properties to shift from the values stated in the information. Processing conditions can cause material properties to shift from the values stated in the information.

It is best for material to flow from thick to thin regions in the part. Place these wells at the base of the sprue to capture the cold material first emerging from the nozzle. 2. Processing conditions can cause material properties to shift from the values stated in the information.

Because low durometer (softer) material is a requirement for this application, the manufacturer considered a switch to a thermoplastic elastomer (TPE). The company tried several TPE grades, hoping to find a material that would eliminate the adhesion problem while providing comparable softness to silicone. With the Avient material, the manufacturer is expected to save $122,000 per year vs. silicone.

A STAND UP PADDLE RISES TO THE TOP WITH NEW MANUFACTURING PROCESS AND MATERIALS Challe nge Accepted. THE IMPACT Finding a material that would add value to the user in the form of a lighter weight, higher performing paddle was critical. Avient was able to help this company evaluate its manufacturing processes and recommend a superior composite material solution.

Processing conditions can cause material properties to shift from the values stated in the information. ELECTRET CHARGING Electret charging works by improving the crystallinity and mechanical deformation of a material, to prevent electret charging from drifting. By introducing additives with charge storage properties, “charge traps” are created which capture the electret charge applied to the meltblown nonwoven material.

The company needed to find the right material that met all their requirements to create the new control grips. The material is also complicated to process, which can increase costs further. The material was customized with the special glow-in-the-dark colorant and laser etched with intricate game logos.
