MCM S.p.A. specializes in the production of rubber gaskets customized for specific fields such as automotive, aeronautical and petrochemical. The company as well manufactures evolast® parts (the new generation of perfluorelastomer) with registered trademark.

Compounds

Overview of a wide range of compounds for standard and none standard applications with approvals and technical details.

To the compounds

O-Rings

MCM S.p.A.’s strength is O-Rings manufacturing. These toroidal rings are made of elastomers at high technological content (FKM, FFKM evolast®, HNBR, VMQ, FVMQ, ACM, Aflas) . . .

O-Rings

evolast® Perfluorinated rubber – FFKM 

FFKM materials are elastomers ­offering the highest chemical and heat ­resistance. Some FFKM types can be ­exposed to temperatures over 300°C. The resistance to chemicals is ­nearly ­universal and ­comparable to that of PTFE.

Quality

MCM S.p.A.’s company mission consists of the ultimate and total satisfaction of our customers. The basic trend of our company addresses the quality of the service as well as our product.

Starting out from this goal, totally shared by the whole organization, the company has given itself such an imprinting that allowed getting the most important certifications, among which we have:

  • Technical Specification ISO/TS 16949: 2009 (quality management for automotive applications)
  • Norm ISO 9001:2008 (quality management)
  • Norm ISO 14001:2004 (environmental management)
  • Agusta Westland approval (helicopters components supply)


Our drive has also allowed several critical approvals of division specifications for Automotive, petro-chemical, military-aeronautical and food industry.

Technical information

Rubber gaskets are statical or dynamic sealing elements that interject between two surface parts to ensure perfect tightness, as to say to avoid gas or liquid leaking.

Sealing elements are physical barriers against potential leaking and their quality reduces to a minimum product loss, premature breakdowns and especially chemical contamination of the atmosphere.


A sealing element made of elastomeric materials is designed in order to be able to be deformed under load pressure, it requires such an impact resistance in order to adapt itself to unevenness of the surface to be sealed and it requires to be sufficiently stiff to be resistant to extrusion, preserving all its physical and chemical properties as long as possible.

Rubber gaskets can be of different kinds: an O-ring, a customized drawing gasket, a diaphragm (membrane) or more complex parts as well; as a supplementary part of an engine, an installation or a machine equipment, its sealing must be designed following specifications that take into consideration the working temperature, the fluids employed in the process, the added pressures and the procedure time.

To the compounds

evolast® – FFKM

The development of FFKM has now raised rubber to a hitherto unknown peak in the sealing applications segment! evolast® combines the excellent chemical and thermal properties of PTFE thermoplastics with the elasticity and superior compressive strain resistance of elastomers.
