• A number of different shapes and
designs are created and simulated to
determine which one works best
• Refining to meet EN standard
• VDT TPEs can help reach compliance
with EN1621-1 level 2 and EN1621-2
level 1
• Optimum protection can be achieved
by combining industrial design and
engineering

In response to the tests, Avient leveraged
its expansive portfolio of specialty additives to tailor
the TPE for enhanced UV resistance and to inhibit mold
growth—leading to an end product that would perform
better for longer.

On one hand, soft materials can reduce shoulder
impact, but it’s tough to find a material that provides
plenty of comfort while also resisting material
breakdown.

They also add important characteristics, such as
SWELLCOAT® water-blocking, water repellence, adhe-
sion, color, and wear and UV-resistance to these and
many other applications.
