FEP or PFA encapsulated Silicone or FKM gaskets

Silicone gaskets encapsulated FEP - PFA PTFE. In toric, rectancugarl and oval format and with camlok closures in Merefsa we have several models of encapsulated silicone gaskets.

Encapsulated Boards of FEP or PFA with FKM or EPDM silicone, used as seals, both in O-ring, square, rectangular, oval and for Camlok type closures, either solid or hollow, with no diameter limit on the O-rings.

When to use encapsulated silicone gaskets?
In some applications such as food contact processes, chemical, pharmaceutical processes, etc; the use of conventional rubbers is prohibited. Corrosion or high temperatures can have devastating effects on the O-rings, causing premature aging and no longer securing the seal, in these cases it is advisable to use encapsulated silicone gaskets.

When to use FKM encapsulated gaskets?
In those applications where high corrosion, as well as high and low temperatures are present or the use of conventional rubbers is prohibited, being in contact with acids, solvents, hydrocarbons, etc. These phenomena can have devastating effects on the sealing gaskets, causing premature deterioration and ceasing to ensure the sealing, in these cases it is advisable to use the FKM encapsulated O-rings.

Comparison of materials for toric:

O-rings in Pure PTFE: PTFE is inert and provides fantastic chemical resistance, but since it is a rigid plastic with virtually no memory, it cannot be used as a compression joint and once disassembled, it will no longer ensure tightness.

PTFE sandwich joints: Despite being economical joints, by design the possibility of permeability on the sides, make it a weak joint and that chemical agents can attack it quickly.

O-rings coated with PTFE: Toric coated with acrylic or latex emulsions with PTFE obtain a low coefficient of friction, but they do not provide chemical resistance and the coating deteriorates very easily.

Perfluorelastomer O-rings: This material is the most advanced that exists to work as a joint, it provides a fantastic chemical resistance in a wide range of temperatures, but the high cost often makes it impossible to apply.

O-rings of metal: They offer good chemical resistance and excellent working capacity with high pressure, but they are very rigid and often expensive.

O-rings encapsulated silicone: Always used as a static joint, the FEP and PFA provide excellent chemical resistance, and the Silicone body has a flexibility that plastic does not have. Preferably we will use the silicone core (-60 to + 260° C) to work with products that require the FDA norm or are in contact with food.The use of FEP jacket will limit the stability to a temperature range lower than that of the PFA that will remain stable up to + 260° C, also having the property of superior resistance to abrasion and pressure.

FKM encapsulated O-rings:Always used as a static joint, the FEP and the PFA provide excellent chemical resistance and the fluorelastomer body, a flexibility that plastic does not have. Preferably we will use the fluorelastomer (-20 to +204° C), taking advantage of its chemical resistance. The use of FEP jacket will limit the stability to a temperature range lower than that of the PFA that will remain stable until +260° C,376/5000 having also the property of superior resistance to abrasion and pressure.

Encapsulated gaskets of FEP or PFA with Silicone and FKM, are used as gaskets in both O-ring, square, rectangular, oval and closures Camlok type, either in solid or hollow format and we can also supply the o-rings with no diameter limit.
