PTFE Compounds, Dispersions, and Emulsions
What are PTFE Wax Compounds?
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.
Micronized Wax Powders
A range of Micronized waxes with varying molecular weights, melting point (97-130°C), densities (0.93-0.98 g/cc), hardness and solubility for a wide range of applications.
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.
Characteristics of Wax Compounds
- Small particle size (<2 µm)
- Tight particle size distribution
- Particles with uniform Morphology
- film uniformity
- excellent dispersion
- paste form for ease of incorporation
- stability, no separation
