Compounding
Compounds transform standard polymers into bespoke high-performance materials – with precisely the mechanical, thermal and optical properties required for a given application. The demand for functionalised plastics is growing with every new project in lightweight construction, electrification and recycling. Biesterfeld supplies compounders and plastics processors with the raw materials required for this – from the selection of additives to the appropriate polymer base.
Our strengths
Comprehensive service
Thanks to our market knowledge across the entire rubber value chain, we can connect you with suitable partners and offer you bespoke solutions combining products, technical expertise and application knowledge.
Extensive portfolio
All the key polymer families in the portfolio – from polyolefins, PVC and rubber, through to silicone and styrene copolymers, right up to thermoplastic elastomers and high-performance polymers – and laboratories across Europe for testing and analysis.
A technical partner to work with, from formulation right through to mass production
Sample batches for trial runs, technical documentation for OEM approvals, and advice on process parameters such as residence time, shear gradient and temperature control.
Our portfolio
Our portfolio covers the most important polymer families: polyolefins (PE & PP), PVC, rubber, silicone, styrene copolymers, as well as thermoplastic elastomers (TPE, TPE-O) and high-performance polymers (engineering resins). In addition, we offer masterbatches – including those from our own masterbatch production facility – flame retardants, impact modifiers and additives for additive manufacturing (3D printing) as well as for photovoltaic applications (solar).
Our customers process these compounds using methods such as injection moulding to produce profiles and pipes, films and tapes, fibres and non-woven fabrics, cable sheathing and rigid packaging – for the automotive industry as well as for numerous other sectors. We are also a sought-after partner for recycled materials and recycled compounds.
Higher recycled content whilst maintaining the same performance, the partial replacement of glass fibres with mineral fillers to optimise costs, and materials for battery casings and lightweight components in e-mobility are among the issues currently occupying compound manufacturers most. At the same time, the industry is under pressure to reduce energy and raw material costs per tonne produced whilst also meeting stricter fire safety and emissions regulations.
We support compound manufacturers with sample batches for test runs, technical documentation for approval processes with OEMs, and flexible delivery quantities ranging from pilot-plant scale to large-scale production. Regional warehousing ensures short response times in the event of production bottlenecks, whilst our applications team provides advice on process parameters such as residence time, shear rate and temperature control.
