Precision Capabilities
Precision Calendering
One of the UK's specialist rubber calendering manufacturers
Colne Valley Rubber specialises in precision rubber calendering for applications where thickness consistency and surface quality are critical. Our process allows manufacturers to obtain rubber sheet with exceptional uniformity, helping improve downstream processing, reduce waste and ensure reliable rubber performance.
What is Rubber Calendering?
Calendering is the process of forming uncured rubber into continuous sheets of consistent thickness and width. At Colne Valley Rubber, we work to your exact requirements, whether for development batches or full-scale production.
We routinely achieve thickness tolerances of +/- 0.08mm. For specialist projects, tolerances as tight as +/- 0.05mm or +/- 0.025mm may be possible depending on the compound, gauge and batch size. This level of accuracy reduces waste, improves downstream processing and helps ensure consistent final product performance.
Rubber Calendering
Custom Options
Our calendered rubber sheet can be tailored to your specific requirements. Thicknesses range from 0.25mm to 10mm, with widths from 20mm up to 980mm. Roll weights can be supplied from 4kg to 250kg, depending on material and gauge.
We can also produce multi-ply laminations and fabric reinforced constructions where additional strength or stability is required.
Rubber Calendering
Slitting & Precision strip conversion
We provide in-house slitting services to deliver rubber sheet cut to your required width, typically down to 20mm. This saves cutting time, reduces material waste and supplies sheet ready for immediate use in your production process.
Materials we Calender
We work with a wide range of elastomer compounds, we also process custom black and coloured formulations.
HNBR
HNBR (Hydrogenated Nitrile Rubber) is a synthetic rubber offering greater strength and chemical resistance than standard nitrile rubber. HNBR is widely used in automotive and oil industries.
FKM
FKM stands for fluoroelastomer, a synthetic rubber celebrated for its superior resistance to chemicals, oils, and high temperatures. It’s commonly used in seals, gaskets, and hoses
Aflas
Aflas is a premium fluoroelastomer renowned for its resistance to demanding environmental conditions. Commonly used in the oil and gas industry, automotive and chemical processing.
EPDM
EPDM (Ethylene Propylene Diene Monomer) is a durable synthetic rubber used for sealing and weatherproofing in construction and automotive applications.
NBR
Nitrile rubber (NBR) is an oil-resistant synthetic rubber which is commonly used in the automotive, aerospace, and industrial sectors, as well as for disposable gloves and various moulded goods.
CR
CR rubber is a synthetic rubber which remains flexible across a broad range of temperatures. Commonly used for wetsuits, sporting equipment, automotive parts, and industrial applications.
CSM
CSM is a synthetic rubber recognised for its excellent resistance weathering. Commonly used for automotive components, electrical cable jacketing, roofing materials, and inflatable boat manufacturing.
Silicone
Silicone rubber is widely used thanks to its unique properties, such as excellent resistance to both high and low temperatures. Commonly used automotive, construction, electronics, and medical industries.
Natural
Natural rubber is a polymer obtained from, most notably the Hevea brasiliensis tree. Its valued for its remarkable elasticity, strength, and flexibility.
Polyurethane
Polyurethane (PU) is a versatile elastomer known for it’s excellent abrasion resistance, high load-bearing capacity, and strong mechanical properties. It is widely used in industrial components such as rollers, wheels, seals, and protective linings where durability and wear resistance are critical.
