Tried & Tested Plastic Compounding Suppliers
Plastic compounding is the process of blending polymers with additives, fillers, reinforcements, and colourants to tailor material properties for specific performance requirements. From improving strength and durability to enhancing flame resistance, processability, or aesthetics, compounding allows manufacturers to engineer plastics that meet exacting end-use and regulatory standards.
At Naphtha Plastics, we support compounders with clean, consistent polymer feedstock - both prime and recycled - alongside high-quality additives, fillers, and masterbatch. Our materials form the foundation for compounds used across industries including automotive, electronics, packaging, construction, and consumer goods.
The Challenge: Consistency and Compatibility
Compounding success depends on tight control of raw material quality. Inconsistent regrind or contaminated feedstock can lead to poor dispersion of additives, colour variability, unstable melt flow, or mechanical failures in the final product. With rising demand for recycled content and custom performance formulations, compounders need reliable, repeatable material inputs to maintain quality and efficiency.
Our Solution: Trusted Feedstock and Masterbatch Supply
We help compounders overcome these challenges by supplying:
- Clean, pre-qualified regrind or off-spec polymers for best performance at a lower cost.
- Performance additives such as impact modifiers, UV stabilisers, flame retardants, processing aids, and antioxidants.
- Masterbatches for blacking off, or matching to a precise colour, compatible with a wide range of polymers.
- Technical guidance on material selection and formulation optimisation.
We understand the processing parameters and final properties you're aiming for, and we source material accordingly.
Benefits For Compounders
Reduced material variation for consistent processing and fewer rejects
Improved compound performance, from thermal resistance to surface finish
Access to cost-effective recycled feedstock without compromising on quality
Support in meeting regulatory and sustainability targets
With Naphtha Plastics as your material partner, you can produce compound with confidence.
Alongside prime materials, we offer a range of recycled options, including post-industrial regrind and reprocessed (repelletised) grades. Recycled plastics have become an essential part of the supply chain, and we’ve been working with them since the early days. Our team can advise on suitable recycled grades to meet both technical and environmental requirements.
We specialise in fast turnaround and small-volume supply. Orders placed today can often be delivered tomorrow, and we’re happy to fulfil anything from a single bag to a full pallet. All our materials are supplied with a Certificate of Authenticity (CoA), ensuring full traceability and peace of mind.
Since 1981, Naphtha Plastics has built a reputation for reliability, responsiveness and hands-on support. We offer more than just materials - we provide honest advice backed by decades of industry knowledge.
