Our Story, Our Science:
Partners in Polymer Innovation and Supply
At Sigma Polymers Ltd, we don't just supply raw materials; we deliver the technical solutions that power the UK's leading plastics manufacturers and converters. For over 20 years, we have been the trusted bridge between polymer producers and innovative product creation, built on a foundation of deep technical knowledge, unwavering quality, and proactive customer service.
​
We are dedicated to enhancing your product performance and streamlining your production, ensuring you receive the right polymer, the right colour, and the right additive, delivered efficiently and responsibly at a highly competitive price.
​
Core Expertise: Fueling Your Production
Our operations are precision-engineered to meet the diverse and complex demands of the modern plastics industry.
We specialise in three critical areas:
​
Masterbatch & Additive Excellence
We are specialists in the formulation and production of high-quality masterbatches and functional additives. Whether you require precise colour matching (from standard RAL/Pantone shades to bespoke effects) or performance enhancers (such as UV stabilisers, flame retardants, or blowing agents), our technical team ensures superior dispersion and consistent batch quality every time.
​
Global Raw Material Supply
We provide innovative and cost-effective supply solutions for a wide range of thermoplastic raw materials. We leverage our global network to ensure a reliable supply of both virgin and recycled/sustainable grades, helping you maintain competitive pricing without compromising quality or production schedules.
​
A Commitment to Sustainable Solutions
In an evolving industry, responsibility is paramount. Sigma Polymers is committed to promoting a circular economy within the plastics sector.
Waste Material Solutions: We offer expert solutions for handling, facilitating, and transforming waste and redundant polymer products. This not only helps you manage excess inventory but, actively supports environmentally conscious manufacturing.
Recycled Materials Facilitation: We connect manufacturers with certified, high-quality post-consumer and post-industrial recycled (PCW/PIW) materials, enabling you to meet sustainability targets and regulatory requirements.
The Sigma Difference: Trust and Technical Support
Our focus is always on simplifying complex supply chains. We are more than a vendor; we aim to be your technical partner.
Hassle-Free Process: We handle the logistics and complexities of sourcing, quality control, and delivery, making the entire process simple and reliable. Flexible solutions to fit in with your schedules.
Decades of experience: We specialise in the complex engineering required to turn recycled plastics into high-performance assets. Working with industry-leading extruders, granulators, and compounders, alongside specialised sheet production for immediate industrial use. By utilising advanced mechanical IV lifting, we don't just recycle plastic we upcycle it, restoring the structural integrity of the polymer to meet the rigorous standards of modern manufacturing
Technical Team: Our highly trained team is available for consultation on material selection, additive compatibility, and processing optimisation, ensuring you get the maximum performance from every product supplied.
