Polymerisation Inhibitors - Nufarm UK

Polymerisation Inhibitors

Nufarm UK Limited is one of the World's principal suppliers of polymerisation control agents for the petrochemical industry.

We produce our polymerisation inhibitor and retarder products at our UK manufacturing facility at Wyke for supply to many of the major petrochemical companies throughout Europe, the Middle East, Asia Pacific and the Americas.

As well as producing industry standard products, we have a successful Research and Development team that have developed and patented a new range of anti-polymerants. This is now enabling Nufarm to provide solutions to polymer problems in a wide range of petrochemical processes. These include retarders and inhibitors for styrenics, together with antioxidants and inhibitors for acrylics, butadiene, ethylene and many more.

Stable Free Radical Inhbitors: Nufarm is one of the principal manufacturers of piperidine based stable free radical molecules, generically known as Tempos. We are lead registrants in REACH for the industry standard molecules 4-Oxo and 4-Hydroxy Tempo and we also commercially produce two other Tempo molecules that have specialist applications in polymer inhibition.
Our Tempo molecules are available in a range of dilutions, solvents and packaging that is best suited to your process

The AHM 700 Series (DNBP plus Tempo above 5% content) is now off-patent in all parts of the World in which we operate. This is the most cost-effective system for many plants and the one-pack product can give reduced polymer and reduced purchase costs and it simplifies logistics and dosing. Many case histories are available to show the product effectiveness. More information can be found in the styrenics section

Nufarm has a very well equipped instrument laboratory at Wyke. As well as GC, LC and FTIR machines we have Mass Spec, pyrolysis Mass Spec, Electron Paramagnetic Resonance (EPR, ESR), Diffential Scanning Calorimetry (DSC), Ion chromatography, GPC and ICP for metals analysis. For other analysis such as NMR we use equipment at local universities. We have recently built a pilot plant (picture right) to allow better simulation of plant injections and operating conditions

We can provide inhibitors and retarders for any monomer. The links opposite provide some basic information on products and case studies for different monomers. For further information please use the contacts at the bottom of the page

Controlled or Living Polymerization is a growing application for the TEMPO type true inhibitors. The Tempos allow polymers to be produced with very low polydispersity and this can give different properties to the final polymer. Please contact us if you would like to discuss this application of TEMPO molecules.

Tempos as oxidation catalysts

Tempos are used as catalysts for mild and selective oxidations and there is a wealth of published articles in journals and patents covering this use. They are used in the paper industry in the pulp bleaching process. Please contact us for further information

Manufacturing

Manufacturing plants at Wyke, Bradford

All of our manufacturing and formulation takes place at the Wyke facilty in the UK. The site is registered to ISO 9001 and ISO 14001 standards. We have manufactured DNBP at Wyke since 1947, firstly as a herbicide and then since the mid-1980s as a polymerisation inhibitor. TEMPOs have been manufactured here since the mid 1990s.
All our products are analyzed before leaving the site by our QC department and Nufarm has a dedicated registration team dealing with regulatory issues, including REACH. All our retarder and inhibitor products will be supported through the REACH registration process. For copies of safety data sheets or product specifications,

Supply Chain

Nufarm have supplied polymerization inhibitors and retarders to to the monomer industry for the last 30 years. We are very proud to state that we have never let a customer down, we have always delivered in time. Our first class Supply Chain team organize deliveries to all corners of the World by road, rail, sea and air. Inhibitor products are normally supplied in bulk isotanks, 1cuM intermediate bulk containers, drums or kegs. Our reliability is such that many of the major producers trust us to be sole suppliers of their inhibitor needs.
