Nynas : adds NYFLEX® 201B and NYFLEX® 2005 to its specialised silicone sealants range

New products NYFLEX® 201B and NYFLEX® 2005 join process oils NYFLEX® 2120B and NYFLEX® 3011, to further complement the companies' silicone fluid replacement portfolio. Naphthenic process oils manufactured by Nynas act as a viscosity modifier in sealant formulations, reducing cost for producers as a partial replacement of silicone fluids. In addition, NYFLEX® oils offer a wide variety of technical benefits.

''NYFLEX® 201B is a medium viscosity oil with low volatility. NYFLEX® 2005 is slightly lower in viscosity, and both provide superior colour stability and a low VOC level,'' says Ghislain de Quatrebarbes, Market Manager Chemical Industry.

Nynas utilises hydrotreatment technology to refine its naphthenic oil to ensure that the product is odourless, colourless and provides a unique UV stability.

'The solvency of naphthenic oils is also a huge benefit,'' adds Ghislain de Quatrebarbes. 'This is the property which gives Nyflex process oils perfect compatibility with the polymers used in silicone sealants, such as polymethyl siloxane.''

With the solvent power of Nynas naphthenic oils aiding their excellent silicone compatibility, a high proportion of Nyflex oil components can be added to silicone sealant formulations.

'Testing shows that even with a 25% loading of Nynas naphthenic oil into the formulation, no bleeding will occur,'' adds Ghislain de Quatrebarbes.

NYFLEX® process oils are available globally in a range of viscosities, providing formulators with security of supply and the flexibility to design the exact silicone fluid to meet their purposes.
