Description:CF3090 is composed of ptfe loaded and modified with silica.
This gasket, in addition to combining an excellent quality of resistance to all chemical agents, except hydrofluoric acid, drastically reduces the main defects typical of pure ptfe: creep and cold flow.
It is suitable for a wide range of fluids, acid substances and strong bases, steam, hydrocarbons, chlorinated solvents, chlorine.
- Ideal for the chemical and pharmaceutical sector
- Compatible with almost all acids and bases
- FDA certified for food use, BAM and Ta-Luft VDI2440
