Antistatic additives differ in chemistry, compatibility and operating mechanism. Some are incorporated into the compound, while others are applied as a surface treatment. These approaches should be evaluated for the intended service.
Identify the actual product and supplier specification rather than relying on an abbreviated trade name. Recommended dosage and processing conditions must come from validated formulation work; a generic concentration is not suitable for every elastomer.
Check electrical performance, migration, appearance and mechanical properties. Evaluate the effects of humidity, cleaning, abrasion and aging where relevant. An internally added material is not automatically permanent, and a surface coating may require its own maintenance or durability criteria. Confirm the finished part against the agreed resistance requirement.
