Fluorination enhances the properties of plastic products
Better properties in practice
The fluorination process enhances many surface properties. It is highly effective in modifying the top material layer without adversely affecting the properties of the underlying material. No other method can achieve such a targeted effect. Fluorination can be applied to all plastics: ABS, EPDM, plastics made of renewable raw materials, NBR, HNBR, PC, PEEK, PMMA, polyamide, polyester, glass fibre-reinforced polymers, mixed polymers, polypropylene, silicone, TPE, etc.
Smoother fluid films and faster drying
Fluorination hydrophilises surfaces, enhancing coating quality through better wetting, film formation and adhesion properties. This yields significant savings when painting, printing or applying decor to the surface. A smoother water film also means more even drying, a higher print quality and less lime and mould formation.
Reduced friction, stickiness and clinging
The stickiness of elastomer components made of NBR, HNBR, EPDM or other types of rubber and silicone is reduced to a minimum. Talcum, silicone oils or other additives are no longer required. These properties are long time stable even if the material is regularly cleaned or sterilised. Contaminants don’t adhere to the surface, so parts remain clean.
Better bonding and adhesion
Fluorination can improve the adhesion properties of plastic materials. The polarity of the surface is increased, thereby improving adhesion and wetting. Lamination lasts longer, flocking is more durable, and the bonding of adhesives is improved.
Surface barrier fluorination
Less permeation, diffusion and migration
This type of fluorination creates a barrier against non-polar substances, reducing permeation, diffusion and migration of shortchain fluids (solvents, petrol, coolants, glycerol, etc.) to a minimum. Additives of the plastic material no longer diffuse through the surface, and elements of the container filling no longer permeate the wall.
Benefits of gas-phase fluorination
- Long-term stability
Depending on the material, the effects achieved on the surface remain stable for several months
- Even application with no geometric constraints
Even deep grooves, undercuts or cavities with small openings are pre-treated consistently. All exposed surfaces have identical properties.
The fully automated procedure facilitates easy control and monitoring of influencing factors, allowing the exact result to be replicated later on.
- Low temperatures
The treatment is performed at low temperatures that doesn't affect the plastic material. Local temperature peaks are avoided.
- Antibacterial effect
Fluorination has an antibacterial effect for a limited period.
- Dimensional accuracy
Fluorination has no effect on part geometry.
