Who we are

Optimised Fibres Ltd was founded in 2007 by Mr John Kynaston.

John created then a high Chrome-Aluminium alloy, known as HC-A, an innovative stainless steel which has since proven to have made a meaningful contribution to the advancement of the refractory technology worldwide.


The company was renamed Optimised Fibres International Ltd in 2018 and has since be run by Monica Woodcock and Alexander Morgan who have a combined 20 years experience in the industry. 


We have a strong presence in the United Kingdom and worldwide (Europe, Nordic countries, Asia, Africa, North America, etc) and serve our clients from the United Kingdom and The Netherlands.

What we do


We manufacture high-quality stainless steel fibres, designed to maximise the performance levels of refractories subjected to very high temperatures, thermal cycling, mechanical shock and exposure to aggressive atmospheres. These refractories are used in today’s manufacturing processes in many industries such as steel, foundry, cement, aluminium, power, incineration, petrochemical, environmental and energy.

Our HC-A (High Chrome-Aluminium) fibres enable refractory manufacturers the production of outstanding high-quality components, which improve the end-user’s competitiveness by surpassing their needs for heat insulation, thermal stability and wear resistance, thus lowering maintenance costs and increasing production efficiency.
