Dupré Minerals was founded in the early 1950’s. Based at Newcastle-under-Lyme Staffordshire, we manufacture an extensive range of high quality products, servicing the Vermiculite, Precision Casting, Friction and Refractory Industries. Dupré combines over 40 years experience with the latest production technology to formulate and manufacture the highest quality products to meet precise specifications.

The processing and manufacture of Vermiculite continues to be one of our core business markets. The established Dupré brand inspired the development of some of the worlds most advanced Vermiculite product formulations. Applications for crude and exfoliated Vermiculites include insulation, friction, horticulture, construction, packaging and wherever lightweight or heat resistant properties are required.

In 2007 we opened our newly constructed Vermiculite exfoliation plant. This, in addition to our already established facility, will offer a bulk storage capacity for over 5,000 tonnes of Vermiculite, safeguarding market supply and offering greater flexibility in service to an extensive customer base.

Vermiculite is a naturally occurring mineral that continues to find niche market applications where fire protection, absorption, and acoustic properties are desired. It is however the thermal insulation properties of Vermiculite that are most commonly sought and Vermiculite is an ideal user friendly option for domestic and industrial insulation solutions.  

The Dupré ‘Micafil’ brand is the market leader for insulation Vermiculite. Micafil is commonly used for a variety of building insulation applications, including internal cavity wall, loft and chimney flue liner.

The new Vermiculite operation also compliments our established range of Refractory, Precision Casting and Friction products

In 2009, we started to provide Micalite Fire-Resistant Vermiculite Boards. Ideal for use in Wood-Burning Stoves and other insulation/fire resistance applications.

Also in 2009, we installed our CNC (Computer Numerical Control) Router capable of accurate cutting and shaping of the Micalite Boards to demanding customer requirements and specifications.

Dupré Minerals operates a quality management system that complies with the requirements of BS EN ISO 9002
