Gaskets are widely used for the safety, containment and hygiene of tanks, reactors, pipelines, etc. Leading PTFE sheet manufacturers are using technology to produce high quality custom made PTFE wrap gaskets. And these gaskets are readily available in various sizes and can be customized to suit a number of applications.

PTFE or polytetrafluoroethylene wrap gaskets are composite gaskets in which PTFE is wrapped around a core insert material. The main advantage of envelope gaskets is that they confer the strength and characteristics of the core material together with the properties of PTFE.

To improve the properties, two or more insert materials can be used to make the joints.

PTFE wraparound gaskets are in high demand by gasket manufacturers due to the physical and chemical properties of the PTFE material. It is widely used in the chemical, petrochemical, pharmaceutical and food industries. In food and pharmaceutical products, the purity of the products is guaranteed by the use of gaskets.

PTFE sheet manufacturers can provide custom designed products using graphite, rubber elastomers, non-asbestos fillers, corrugated metals, etc.

These gaskets show increased resistance to most chemicals.
They offer high performance due to the strong C-F bond of PTFE.
PTFE seals also contribute to vibration-free and noise-free operations.
PTFE wrap-around gaskets are an ideal sealing solution in low to high corrosion environments as they are anti-corrosive in nature.
In high pressure environments, PTFE can withstand pressure without breaking.
PTFE gaskets have the robustness to withstand temperatures up to + 250 ° C depending on the gasket material used.
Definitive uses for PTFE wrap-around gaskets that make them so popular in all industries:

Gasket manufacturers provide a number of sealant solutions for the pipe industry. PTFE envelope gaskets are a very useful sealant for liquids and gases inside pipes. They help prevent the leakage of acids and chemicals that pass through flange gaskets, valves, etc.

Food processing
Food processing companies need to be very careful about contamination to avoid mishaps. PTFE material offers the qualities of a perfect sealant that prevents contamination from interfering with the properties of edible substances that come into contact with them.

The food processing industry uses PTFE wrap-around gaskets due to its odorless and non-polluting characteristics. Furthermore, PTFE is also an approved food grade material.

PTFE material has high chemical resistance. Therefore, the petrochemical industry uses PTFE gaskets as a reliable sealant for mild to aggressive chemical environments.

PTFE gaskets are used in high-end scientific laboratories where chemicals are handled to deliver various product formulations.

The pharmaceutical industry uses various ingredients to produce medicines and personal care products. Reactive substances are managed in pharmaceutical production facilities. PTFE wraparound gaskets are extremely useful to prevent contamination of medicinal and care products.

Other uses
PTFE gaskets are used with glass or steel, plastic or ceramic lined flanges. Gasket manufacturers design PTFE sealants for the dual purpose of ensuring product quality while protecting service life and property at the application site.
