For seals used in sensitive areas, e.g. gas fittings or in the food sector, approval from the relevant institution is often required. In some cases, a declaration of no objection is also sufficient; this is often referred to as a certificate of conformity. Some examples of our approved or compliant mixtures (compounds) follow below:
