Introduction
The BORFLEX Group stands out for its ability to produce high-quality extrusion-calendered rubber compounds. These compounds, which are unique in France, offer customisable solutions suited to a wide range of industrial applications. This article explores in detail what BORFLEX’s extrusion-calendered compounds are, their applications, and the group’s unique capabilities in producing them.
1. Technical Definition of Extrusion-Calendered Compounds
BORFLEX’s extrusion-calendered rubber compounds are elastomeric materials produced using a process that combines extrusion and calendering. Extrusion involves forcing a rubber compound through a die to produce a continuous shape. Calendering, on the other hand, is a rolling technique that produces precise and uniform thicknesses. This dual process ensures homogeneity, consistent thickness, optimum mechanical strength and the absence of air bubbles in the elastomers, making extrusion-calendered compounds the materials of choice for numerous industrial applications.
2. Industrial Applications
BORFLEX’s extrusion-calendered compounds are used in a range of industrial sectors, including:
1. Building Materials
Floor coverings: Tiles, paving slabs or carpets, floor tiles.
Facade Panels: Weather-resistant external cladding.
Insulation: Thermal and acoustic insulation for buildings.
2. Electronic Components
Enclosures and Cages: Enclosures for electronic devices, protective cages.

3. Capabilities and Distinctive Features of the BORFLEX Group
For over 65 years, the BORFLEX Group has specialised in rubber compounds, and its formulations and compounds are distinguished by their unique properties:
Precise Thickness: Extrusion-calendered compounds can be produced with a thickness ranging from 1.2 mm to 14 mm, with an impressive tolerance of ± 0.3 mm.
Flexible Packaging: Products can be packaged in sheets or rolls, depending on the customer’s specific requirements.
Maximum width: BORFLEX can produce compounds with a width of up to 1,000 mm, thus offering great flexibility for a variety of applications.
4. Customisable formulation
One of BORFLEX’s key strengths is the ability to tailor the formulations of its compounds to the specific requirements of the end product. This customisation takes several factors into account, such as:
• Mechanical properties: Tensile strength, flexibility, hardness, etc.
• Chemical resistance: The ability to withstand various chemical agents and corrosive environments.
• Environmental conditions: temperature, humidity, UV exposure, etc.
5. Production of extrusion-calendered compounds
The production of extruded-calendered compounds at BORFLEX follows a rigorous process:
• Selection of raw materials: Selection of polymers, additives and fillers in accordance with the customer’s specifications.
• Extrusion: Mixing and extruding raw materials to produce a continuous shape.
• Calendering: Rolling to achieve the desired thickness and width.
• Quality Control: Checking dimensions, uniformity and mechanical properties.
6. Cutting and Packaging
BORFLEX also offers bespoke cutting services, enabling customers to receive ready-to-use products. Cutting capabilities include:
• Cut-to-size: According to the specific dimensions required by the customer.
• Packaged in sheets or rolls: To make transport and end-use easier.
