MCOR

Product catalog summary

Introduction
The MCOR Multi-Component Precision O-Ring was specifically developed for NASA applications. It addresses previously unmet needs in chemical and temperature resistance, offering unprecedented compression set values.

Composition
The MCOR consists of two elastomer materials seamlessly bonded together. The outer cover is made from chemically resistant materials, while the core is composed of elastomers with excellent physical properties.

Materials and Design
The O-ring features a combination of FPM for the cover and silicone for the core, allowing it to operate in temperatures ranging from -50°C to +220°C. It exhibits excellent compression set and chemical resistance.

Application Range
MCOR is suitable for use in aggressive media across a wide temperature range. It is available with optional back-up rings made of PUR or PTFE, which can be directly connected to the seal.

Installation and Surface Quality
The O-ring is designed for simple snap installation. Surface quality specifications include a sealing surface roughness of Ra ≤ 0.8 µm and Rt ≤ 3.6 µm, with groove base side roughness of Ra ≤ 2.3 µm and Rt ≤ 15 µm.

Conclusion
The MCOR O-ring offers a robust solution for demanding applications, combining high chemical resistance and excellent physical properties to meet the rigorous requirements of advanced engineering projects.

Catalog excerpts

Mehrkomponenten-Präzisions-O-Ring Multi-Component Precision O-Ring Multi-Component Precision O-Ring Der Mehrkomponenten-Präzisions-O-Ring MCOR wurde speziell für Einsätze der NASA entwickelt. The multi-component precision O-ring MCOR was specially developed for a NASA application. Durch die Entwicklung dieses Dichtelementes lassen sich nun bislang nur unzureichend oder nicht abgedeckte Einsatzspektren im Bereich chemischer Beständigkeit und Temperatur abdecken mit bisher nicht erzielten Rückstellvermögen. The development of this seal has opened up new dimensions in the field of chemical and temperature resistance with compression set values not previously realised. Der MCOR besteht aus zwei unterschiedlichen Elastomeren, die beide direkt miteinander verbunden sind, wobei der äußere Mantel den Kern nahtlos umgibt. The MCOR consists of two different elastomer materials fixed to each other. The outer cover surrounds the core seamlessly.
