Compounding
Custom Rubber Compounding
Harltex develops and manufactures custom rubber compounds for moulding and extrusion applications across a range of industrial and engineering sectors. With more than 40 years of manufacturing experience, compounds can be developed around specific material, processing and application requirements.
What is Rubber Compounding?
Rubber compounding combines a base elastomer with fillers, curing agents and other additives to produce a material with defined physical, chemical and processing properties.
Compound formulation can be adjusted around requirements such as temperature, fluid exposure, hardness, flexibility, mechanical performance and manufacturing process.
Harltex develops bespoke rubber compounds for extrusion and moulding applications, with material selection and formulation based on the requirements of the finished component.
