Development and production Scalability
Custom Rubber Compounding
Tailored Rubber Compounding for Superior Performance
Rubber compounding allows elastomer materials to be engineered for specific performance requirements. By carefully selecting polymers, fillers, oils and curing systems, compounds can be tailored for properties such as hardness, chemical resistance, durability and processing behaviour.
At Colne Valley Rubber, our in-house mixing capability is built around proven, production ready formulations developed through years of experience serving demanding industries. Each batch is produced with consistency, performance and process ability in mind, ensuring clean calendering, controlled shrinkage and reliable physical properties.
Proven formulations, tailored to your needs
Whether you need a firmer durometer for improved wear resistance, a specific elongation target, or a bespoke surface finish, we deliver precise colour matching and hardness control to suit your product and process.
From R&D trials and prototype batches through to full-scale production, we support projects at every stage. Our development batches allow customers to evaluate and qualify materials quickly and cost effectively, before transitioning smoothly into consistent repeatable production volumes.
Rubber Compounding
Specialist Materials & Trusted Partnerships
For projects requiring specialist elastomer systems, including flame-retardant, conductive or chemically resistant compounds, we collaborate with a network of a audited UK manufacturing partners. This ensures consistent material quality, traceability and dependable supply for demanding applications.
Rubber Compounding
Quality & Control
Every batch is produced under our ISO 9001 quality management system with full material traceability. Carefully controlled mixing processes ensure uniform dispersion, stable processing characteristics and consistent material performance.
Versatile Base Formulations
We maintain a portfolio of proven base formulations across a range of commonly used elastomers, including EPDM, NBR, HNBR, PVC/NBR, CSM, and Natural rubber (NR).
These compounds provide a reliable starting point for many applications and can be tailored to achieve specific mechanical properties, chemical resistance or environmental performance.
EPDM
Excellent resistance to weathering, ozone, heat and water. Commonly used for sealing and outdoor applications.
NBR
A synthetic rubber valued for it’s oil and fuel resistance, widely used in hoses, seals and industrial components.
HNBR
A high performance nitrile offering improved heat resistance, strength and chemical stability.
PVC/NBR
A blend combining oil resistance with improved abrasion and flame resistance, often used in hose coverings.
CSM
A durable elastomer with excellent chemical, ozone and UV resistance for demanding environments.
Natural Rubber (NR)
Known for high strength, elasticity and abrasion resistance in dynamic industrial applications.
Peroxide Cure Silicone – Manufactured In-House
We manufacture peroxide cure silicone In-House, giving customers greater control, consistency and flexibility. In-house production allows formulations to be tailored to specific performance requirements while maintaining strict quality control, full traceability and responsive lead times.
Flexible Supply Options
Compounds can be supplied as uncured sheet, calendered rolls or strip. Our team can also provide technical and production guidance to help ensure the most suitable compound format for your application.
