Reliable JIT supply chain: The Versalloy material needed by the customer was reliably supplied by Avient in just three weeks instead of the six week lead time offered by the competitive TPV material supplier. attended molding trials to ensure the parts processed easily met performance requirements.

They are high-molecular-weight additives and as such are conductive along their full molecular chains.

Planning now for transitions will help avoid supply chain disruptions in the future.
