PTFE Compounds, Dispersions and Emulsions

What are PTFE Wax Compounds?

PTFE Compound Creation

Waxes which have been melted into a liquid media and later recrystallized under controlled temperature conditions.

Wax performance  can be defined by their chemical structure and molecular weight.

Compound Melting Point Chart

Waxes are melted in a variety of media such as Linseed Oil, Soya Alkyd Oils, Mineral Oil or varnishes such as Alkyds or hydrocarbons. This combination allows for print applications to achieve a high quality finish while improving processing conditions by ease of incorporation.

Benefits of PTFE Wax Compounds

Rub Resistance The ability to withstand the effects of repeated rubbing and scuffing, and to preserve print integrity and quality.
Slip / Non-skid Control the Coefficient of Friction of surfaces
Block Resistance Blocking is the undesirable sticking together of two printed surfaces when pressed together or placed in contact with each other for an extended period of time.
Off-setting Transfer of Ink from one sheet to another
Gloss Light Reflectance
Over-Printability Ease of printing of layers

Oil or varnish adds gloss, hardness, and lubricity to ink formulations. Waxes add mar, scuff, and rub resistance, slip, and anti-blocking. We have found that melting and compounding the two into a paste provides a synergy that significantly improves these properties.
