Consider, too, that additional supply chain issues regarding pigments, stabilizers and additives that are regularly rationalized out of production can leave you scrambling for last minute formulation alternatives that require requalification. Thanks to our strong supplier relationships, we are typically aware of these changes ahead of time and often will have an alternative formulated before discontinuation affects the supply chain.

Good electrical performance can be offered at a lower hardness compared to silicone or rubber alternatives. Compared to rubber and silicone alternatives they simplify manufacturing with single-step fabrication, reducing the energy used in production and can be overmolded directly onto non-polar polymer substrates such as polypropylene (PP) and polyethylene (PE).

High density polymer-metal composites are an ideal alternative to lead and other traditional metals
