VIRIDYN TFMA-6
HYDROPHOBIC, OLEOPHOBIC PLASTIC ADDITIVE
VIRIDYN TFMA-6 is a hydrophobic and oleophobic dry-melt additive for polypropylene and polycarbonate used to create low-retention surfaces.
Application methods: Dry melt additive for injection moulding
Color: Colourless
Water contact angle: over 110°
Mineral oil contact angle: over 65°
TFMA-6 is compounded into polypropylene at 0.5% to make pipette tips and other plastic devices water, oil, and solvent repellent.
TFMA-6 prevents water, oil, buffers, solvents, biological-fluids, and other materials from sticking to device surfaces.
TFMA-6 is used in industrial, research, and biomedical applications for plastic devices such as pipette tips, tubing and micro-centrifuge tubes.

VIRIDYN TFMA-6 is provided as a solid that is usually ground into a fine powder by a compounder.
Compounding is a process, in which a polymer resin is melted and mixed with additives such as VIRIDYN TFMA-6.
Melt the polypropylene and mix in VIRIDYN TFMA-6 at concentration of 0.5%.
It is very important that a uniform distribution of VIRIDYN TFMA-6 in the polypropylene is achieved.
The end mixture or composite is now ready for injection moulding using instructions appropriate for the moulded parts being produced.
The VIRIDYN TFMA-6 containing composite must not be heated above 250°C.
