OVERMOLDING One of the largest areas of growth for TPEs is overmolding. With new innovative technologies, Avient continues to develop TPEs that bond to a variety of substrates. Relocate the gate so flow occurs in only one direction.

One approach is to substitute metals with reinforced thermoplastics. This design flexibility also enables engineers to reassess assemblies and take advantage of consolidating multiple parts into one molded offering. HOW SUPPLIERS CAN HELP EVALUATE MATERIAL TRANSITION Successfully using composites goes beyond simply swapping one material for another.

This innovative equipment technology is a single unit, developed for a range of applications with sustainability in mind.   These high-accuracy technologies ensure continuous and consistent delivery of liquid color & additives, reducing overall waste. A trials kit option is available, using the ColorMatrix FlexOne technology, but in a camera-sized bag for efficient on-site customer testing.

In addition to Hammerhead™ FR panels, Avient will showcase technologies that offer high strength, weight reduction, and durability for a wide range of industries and markets, including:  Upcoming high-performance carbon composite technologies By intersecting our broad portfolio of technologies with the product roadmaps of our customers, we help create differentiated and high-performance products that make the world better and more sustainable.
