Specialist Materials for Industry & Science


At M&I Materials we manufacture a diverse range of products for use in many markets around the world. We are constantly striving for improvement and have expert technical and engineering teams that are focused on application optimisation.

Our Apiezon range of products have an enviable track record in many fields including Aerospace, Semiconductor, Laboratory, Electronics, Etch Resist and Cryogenics. The Apiezon greases are particularly popular for High Vacuum applications.

Metrosil is our range of silicon carbide based voltage dependant resistors and their applications make use of its non-linear properties to provide an ‘electrical safety valve’ for protecting equipment and insulation from the effects of over voltages. Metrosil is commonly used to protect field coils, contactor coils, relay coils and solenoids, current and voltage transformer protection and to improve the sensitivity and protection of High Impedance Relays.

MIDEL is the world’s leading brand of ester-based dielectric fluids and is chosen by utilities and transformer manufacturers worldwide because of its excellent track record and ability to minimise risk.

MIVOLT is a range of dielectric liquid coolants suitable for the thermal management of electrical systems. As non-conducting fluids, the range offers a simple solution to temperature control because they can come into direct contact with components – taking heat directly away from the source with no reliance on a secondary indirect cooling system.

Performance Biolubricants is a division of our business dedicated to developing high-performing Environmentally Acceptable Lubricants (EALs) for applications in the hydraulic fluid, industrial chains, motors, injection moulding and bicycle chain lubrication markets.

Wolfmet is a high performance tungsten heavy alloy that provides excellent service in thousands of applications including Aerospace, Motor Racing and Nuclear Medicine.
