Polymers and Pre-polymers
Toll manufacturing and the optimisation of polymerisation processes is a core part of Witton’s business. Many common monomers, with the exception of ethyl acrylate or acrylamide, can be used with peroxide or azo initiators. Polymerisation reactions can be carried out in water or solvent. Our reactors are equipped with condensers and solvent can be stripped from polymer solutions using vacuum if required. Witton has considerable experience of manufacturing prepolymers from isocyanates such as MDI, IPDI and oligomeric isocyanates (but not TDI or HDI) reacted with polyols for use in sealants and adhesives. The company is skilled in the production of latexes for use in coatings and surface treatments.
