Micropowders Lubeflon

PTFE can be used as an additive in polymers, rubbers, oils and paints to modify their surface properties, wear and abrasion resistance, friction coefficient, or to adjust their viscosity. For these applications, LUBEFLON micro powders are suitable: they are made by PTFE with a molecular weight up to 2 orders of magnitude lower than molding standard PTFE and with a low size to be easily dispersed in the matrix.

POLIS produce micropolveri di PTFE a partire da PTFE vergini. Esegue e controlla tutte le fasi che conducono al prodotto finale:

• Fine powders choice (FP product line)
• PTFE suspension choice (product line F)
• Method of reducing the molecular weight
• Particle size distribution of the final product

All these variables have a role in defining the main characteristics of LUBEFLON micro powders: Particle size distribution (PSD), particles hardness and friability, Dispersibility, Specific surface area (SSA), Thermal stability, Molecular weight (melting point and MFI), Acidity.

Tutte le micropolveri prodotte da POLIS hanno il contenuto di PFOA conforme alle direttive Europee Reach e POP (Persistant Organic Pollutants), ovvero un livello massimo di PFOA residuo inferiore a 25 ppb.

Versions compliant to EU 10/2011 and FDA 21 CFR 177.1550 directives on food contact are also available.
