Solvay, manufacturer of advanced materials and specialty chemicals, has announced that its Solef PVDF has been chosen  by Scinor Beijing Membrane Technology to optimise its ultrafiltration membranes.

Scinor’s technology, known as Thermally Infused Phase Separation (TIPS), has applications in reverse osmosis pre-treatment as well as industrial and drinking water applications. The chemical resistance of Solvay’s Solef polyvinylidene fluoride (PVDF) was one key factor in Scinor’s decision, as well as its suspension polymerization process for the material, which makes it possible to produce homogenous, linear fibres designed for TIPS and similar ultrafiltration processes.

Scinor’s TIPS technology offers an alternative to more conventional Non-solvent Induced Phase Separation (NIPS) solutions. Unlike NIPS, TIPS filters are isotropic, meaning their mechanical properties are more uniform throughout the membrane structure. Due largely to the consistent quality and performance of the Solef PVDF, there is lower fibre breakage and more consistent, reliable filtration. The result is that Scinor’s TIPS membranes can deliver higher flows while consuming less energy.

Brian Baleno, business development manager for Industrial, Energy and Environment at Solvay’s Specialty Polymers global business unit, said: “Solvay’s commitment to sustainability and the environment is demonstrated through its collaboration and technical support for leading industry innovators like Scinor Beijing Membrane Technology.”
