AFT Fluorotec Ltd is a group of companies based in England around the outskirts of London in Welwyn Garden City and Kent. We specialise in engineering polymers, creating sustainable solutions in plastic for our customers.

Industry leading fluoropolymer components and coatings

When we began, our collective ambition was to be a flexible customer-driven company, capable of giving clients exactly what they needed and not be limited to supply from a rigid product portfolio offering inflexible lead times. More than a decade later we have grown from the '3 guys in a shed' and developed into a team of 100 dedicated individuals, each bringing their own strengths, skills and experience and each fully understanding the fundamental importance of that original ambition to the success not just our business, but our customers as well.

Listening to our customers remains core to our approach whether that be identifying and rectifying a frustration or developing a new manufacturing process to support our customers' ambitions, our goal remains the same – To supply customers exactly what they require when they need it and back this up with commercial competitiveness and an ISO-approved quality system.

Whilst our company beginnings were focused around PTFE and fluoropolymer moulded and machined parts, the demand for other plastics and PTFE and associated coatings from our customer base pushed our investment and development of these additional areas. We are strong believers in reinvestment, evident in our facilities and plant which are the newest and most advanced within the UK Fluoropolymer processing and plastic machining industries. We have no ideal size shape or quantity. Our resource is so broad and varied we can handle all shapes, sizes and quantities of product.

One big market is the food processing and the industrial baking industry, providing non-stick coatings for bakeware, cookware and other associated products. However, the requirement for Fluoropolymer coatings in other sectors is limitless, primarily used for their low friction or chemical resistance or non-stick properties.

When you choose to work with us, you’ll find our focus is on great quality and service. We work to ISO 9001:2015 approved procedures and are also ISO 14001:2015 certified.

As well as supplying a wide range of industries with stock coatings, our expertise means we can tailor the properties of different coating materials to suit your individual requirements. Materials include PTFE, VICTREX PEEK, FEP, PFA, ETFE, Halar ECTFE, Teflon and Xylan.
