FFKM materials are elastomers ­offering the highest chemical and heat ­resistance. Some FFKM types can be ­exposed to temperatures over 300°C.

evolast® combines the excellent chemical and thermal ­properties of PTFE thermoplastics with the elasticity and ­superior compressive strain resistance of elastomers.

evolast® is used in the chemical industry, in medicine and in food industry. It is also used in oil and gas production, and in processing all of the above products, as well as in many other applications where seals are expected to perform to highly exacting standards.

Chers clients

Vous êtes depuis de nombreuses années client de United Seals Asemia  . Ces dernières années nous nous sommes toujours efforcés à être un bon partenaire et à vous livrer des produits de qualité en temps et en heure à des prix concurentiels  .

Ceci sera bien entendu encore le cas dans le futur mais sous un autre nom de société . Notre actuel partenaire de production M.C.M Spa en Italie , fabricant d’élastomères de haute qualité (spécifiquement pour des joints d’étanchéité ) ainsi que O.L.Seals A/S au Danemark producteur de renom de joints en PTFE se sont associés afin de fournir leurs produits  de façon commune dans le futur .

Notre société United Seals Asemia positionnée au centre de l’Europe de l’ouest est de ce fait un partenaire idéal pour atteindre cet objectif ; ce qui explique cette acquisition par M.C.M Spa .

Notre nouvelle entitée mcm-oL seals NV continuera bien entendu à stocker et commercialiser la gamme  de produits fournie à ce jour . Du fait de la fusion des unités de production Italienne et Danoise , nous pensons qu’en tant que producteur direct d’un vaste programme d’étanchéité , pouvoir être un partenaire encore plus précieux .

En ce qui concerne le personnel , aucun changement n’aura lieu . Vos contacts actuels seront comme auparavant entièrement à votre service . Ces modifications seront d’applications dès le 01 janvier 2016 .

Nous nous réjouissons déjà de la poursuite de notre bonne collaboration .
