675,000+ Parts Produced Every Year

Esspee produces over one million machined parts every year from its facility located in St. Helens, Merseyside. We also have sales offices in Stourbridge (UK), Dubai and Jiangsu (China).

Our varied product range spans a variety of material types which we have broken down below.

Advanced Calcium Silicates

Our wide range of advanced calcium silicates offer extremely stable thermal conductivity values across a wide range of temperatures and applications.

Calcium Silicate materials can operate continuously at 1000°C without deterioration or excessive shrinkage while maintaining high levels of compressive and flexural strength.

As well as being able to withstand aggressive thermal cycling, Calcium Silicates are an extremely versatile group of products that we can intricately machine to optimise their performance in the most demanding mechanical and thermal applications.

Our bespoke components are supplied across many industries including
Aluminium, Specialist Alloy production, Magnesium, Aerospace, Petrochemical and Power Generation.

Advanced Wear and Bearing Materials

Esspee are delighted to have been appointed as distributors and machinists of Tenmat’s advanced wear and bearing resistant products.

Railko grades are advanced engineering composite materials, exclusively manufactured by Tenmat. Railko started producing high quality, selflubricating components in 1957 and became one of the leading suppliers for bearings and wear parts in the marine and rail industry.

Feroform grades are a range of proprietary Tenmat formulations, consisting of a friction modified cured Phenolic resin matrix with high performance fabric reinforcement. Feroform grades are used as bearings in aggressive environments, where low friction, strength and durability are all essential.

Engineering Composites

Esspee’s comprehensive range of Engineering Composites are manufactured using reinforced matrix layers, which are impregnated with assorted resins and then cured under heat and pressure.

Various types of reinforced materials are used, such as Cellulose paper, Mica paper, Polyester, Cotton, Glass, Carbon, Synthetic fibre & Specialist fabrics. The most commonly used types of resin are Polyester, Epoxy, Phenolic, Polyimide, Silicone and Vinylester.

Our wide selection of adapted resin formulations, coupled with the combination of advanced reinforced layers, enables us to supply intricately machined parts from a wide range of industrial composites. All of our composites have a vast array of mechanical, electrical and thermal properties designed to suit the most demanding of applications

High Performance Engineering Plastics

With over 50 years of experience in the machining and fabrication of high performance plastics, Esspee offers a comprehensive range of materials combining performance at elevated temperatures with chemical resistance and enhanced mechanical properties.

Esspee’s range of engineering plastics are an effective alternative for metal parts in many manufacturing processes. They are thermally and electrically insulating, lightweight, have good wear properties and are extremely cost effective when compared to metal engineered components.

Including Peek, Nylons, Acetals and GRP’s, our manufacturing department can produce bespoke precision parts to drawing, along with a fabrication service, where we incorporate the finished parts into sub or final assemblies.

Industrial Millboards

Industrial Millboards are strong, thin, dense boards with excellent insulating characteristics that are used within a wide variety of applications where thermal performance, minimal heat loss and exceptional wear resistance are required.

Millboards typically operate in a temperature range between 850°C and 1300°C which makes them the ideal solution for all high temperature gasketing applications.

Industrial Millboards are made from mixed refractory fibres, clay, inert fillers and a small amount of organic and/or inorganic binders for increased handling strength.

In addition, Industrial Millboards have become the industry standard solution for industrial roller cladding, where the materials design meets the most stringent requirements of glass and steel producers worldwide.

With an extensive stock of Industrial Millboards and access to our pressing and machining facilities, we can offer precision pressed gaskets or cut and bespoke machined parts to your exact specifications.

Specialist Performance Products

Our dedicated global procurement team are continually searching for new manufacturers and products that will increase the range of applications and performance levels of our resistant materials.

Our newest selection of special performance products are designed to maximise durability and performance in demanding and aggressive thermal environments by increasing campaign life and energy efficiency.

Our ‘SP’ materials have been designed and formulated by working closely with our customers to understand their precise requirements. Our aim is to deliver improved technical benefits, increased efficiency and quality.


Esspee’s exclusive range of ThermTek® Fibre materials deliver thermal efficiency at high temperatures and combine the advantages of low heat storage and resistance to thermal shock.

Our ThermTek® products are available in sheets, rolls and mouldable form in both Ceramic and Bio-Soluble formats. ThermTek® products have a wide range of thermal performance and physical characteristics, which offer solutions to numerous thermal processing applications.

ThermTek® is extensively stocked by Esspee and designed to suit your precise requirements. ThermTek® blanket can be supplied as complete rolls or cut-to-size strips. Our sheets can be cut and extensively machined while our papers are ideal for pressed and die cut gasket applications. ThermTek® bulk fibre is commonly used in the manufacture of other ceramic fibre-based forms such as our bespoke vacuum formed shapes and mouldables.

Thermal Performance Materials

Esspee offers an expansive selection of advanced cement, calcium silicate and alumina reinforced materials for use in thermally and mechanically demanding applications.

We work closely with leading global material manufacturers to combine our machining and fabrication expertise to offer bespoke parts across a huge range of international industries.

Selected for excellent temperature resistance and low shrinkage, our calcium silicate and cement materials guarantee high levels of mechanical performance at elevated temperatures.

Zicar products are specially formulated composites designed to work in excess of 1200°C whilst maintaining their strength and stability in demanding industrial applications.


Zircar products are an extensive line of advanced high-performance ceramic composite materials that excel in demanding thermal, structural and electrical insulating applications.

Ranging in temperatures from 600°C to 1650°C, Zircar products perform at levels where conventional calcium silicates can no longer operate at optimal levels.

Zircar composite materials have become globally recognised for use in induction melting, forging and heat-treatment applications, investment casting, glass processing and hot pressing, as well as many other specialist and high temperature electrical applications.

As long standing distributors of Zircar Refractory Composites, Esspee stock and supply sheets, tubes and cylinders, all of which are backed up with our comprehensive machining service that enables us to produce intricate bespoke components across the range.
