In the specific form the encapsulated gaskets consist of a core of elastomeric perfectly coated fluoropolymer FEP or PFA. Basically the two types of products differ for a different resistance to temperature and abrasion. The inner core is Viton® or Silicone. They are used which require a high chemical resistance and product purity. Used in Industries • Chemical. • Petrochemical. • Food. • Pharmaceutical. Operating temperature FEP lining: • FEP / Silicon: -60 ° C to + 200 • FEP / Viton®: -20 ° C to + 200 Operating temperature PFA lining: • PFA / Silicon: -60 ° C to + 260 • PFA / Viton®: -20 ° C to + 200 This type of gasket offers greater resistance to abrasion.
