Our Solutions
Driving Performance in Polymer Manufacturing
​
At Sigma Polymers Ltd, we deliver the complete technical and supply ecosystem required by modern plastics manufacturers. Highly technical materials in our solutions are engineered for consistency, performance, and efficiency, ensuring you get the right materials and expertise to optimise your production and achieve your sustainability goals.
Unlike the slow-moving 'sales-first' approach of industry giants, we focus on engineering-led partnerships, combining a deep understanding of your production processes with the ability to react and adapt at a moment's notice.
1. Custom Masterbatch & Additive Systems
This is more than just colour; it’s about engineering the precise properties your final product requires. Our technical team specialises in developing high-quality, high-concentration masterbatches that ensure superior dispersion and colour consistency across every run.
Colour Masterbatch
Precision Colour Matching: From standard RAL and Pantone references to bespoke, complex shades and effects (metallic, pearlescent, sparkle). We ensure batch-to-batch consistency and thermal stability for demanding processing conditions.
Functional Additives
Enhance the physical properties and longevity of your polymers. We supply targeted additives including UV Stabilisers, Flame Retardants, Antioxidants, Processing Aids, and Blowing Agents, all designed to boost performance and cost-effectiveness.
​
Need a custom formulation? Our lab facilities can develop a masterbatch tailored precisely to your base polymer and end application requirements.
2. Global Raw Material Supply
We serve as your strategic partner for securing a reliable and cost-effective supply of thermoplastic raw materials. We utilise our extensive global network to source and deliver prime and off-prime grades directly to your facility.
Commodity Polymers
Polypropylene (PP), Polyethylene (LDPE, HDPE), Polyvinyl Chloride (PVC).
Engineering Polymers
ABS, Polycarbonate (PC), Nylon (PA), and speciality compounds for high-performance applications.
Material Brokerage
Leveraging our market insight to offer competitive pricing and managing the logistics (including customs and transport) to ensure a seamless, just-in-time delivery experience.
​
Our commitment is supply security and competitive purchasing power.
3. Sustainable Polymer Management & Waste Solutions
Commitment to resource recovery is no longer optional, it’s essential. We help manufacturers responsibly manage their polymer waste streams and integrate high-quality recycled content.
Waste Materials Services
We offer structured solutions for managing your redundant or scrap polymer materials, including:
Buying & Facilitation: Purchasing non-conforming or redundant virgin and scrap materials.
Recycling Services: Facilitating the processing of post-industrial (PIW) and post-consumer (PCW) waste into reusable flake, regrind, or compounded pellets.
Post-Consumer Washed Bottles & Recycled Content
We specialise in supplying certified, high-quality recycled polymer grades, such as rPET, rHDPE, and rPP. By integrating these materials, you can meet regulatory targets, demonstrate corporate responsibility, and maintain product quality.
​
Let us turn your polymer waste into a sustainable resource.
