Product Description

What Is Expanded PTFE Gasket Sheet?

Kaxite Kaxite 8600 Expanded PTFE Gasket Sheet is a soft and also compressible gasket material manufactured from completely absolutely pure multi-directionally expanded PTFE. Expanded PTFE Gasket Sheet is actually resistant to almost all chemical compounds as well as has excellent creep and cold flow resistance. It can withstand a wide range of pressure and temperature conditions, and also it is suitable for tight sealing of bolted joints in most industries like chemical, petrochemical, food, power generation, pulp and paper and other general industrial application.

Ningbo Kaxite as the one China leading Manufacturer and supplier of expanded PTFE gasket sheet with competitive price to the world market, our EPTFE gasket sheet is also suitable for sealing flanges with unusual surfaces. It will not present the cold flow issues in comparison with virgin PTFE, or the hardness problems compared with some filled PTFE products. It has superb sealing overall performance, and can be cut easily and split up cleanly from flanges after using. This product is FDA compliant.

In order to offer a fast and efficient service to our customers, we stock a large quantity of Expanded PTFE Gasket Sheet in different thickness and dimensions. The thickness of expanded PTFE Gasket sheet we produce and stock can be from 0.5 mm to 8 mm, and the width and length usually 1520mm. Customers special dimension sizes needed is acceptable.

Application of Expanded PTFE Gasket Sheet

Expanded PTFE gasket sheet material conforms to FDA rules for food contact. Expanded PTFE gasket sheet is an all purpose gasket sheet that will replace all other kinds of PTFE sheet. It will eventually seal all aggressive chemicals over the whole 0 to 14 pH range, except molten alkali metals and elemental fluorine. Constructed from 100% virgin PTFE, and expanded ptfe gasket sheet is perfect for industries such as Iron and Steel manufacturing, Food and Beverage, Power Generation, General Chemical, Petrochemical, Pharmaceutical, Pulp and Paper and Marine.

What Advantages Make the Expanded PTFE Gasket Sheet Unique?

As we all known that expanded PTFE gasket sheet is used widely for general industrial applications and have very good sealing effect when it is used as a seal gasket. And below content is about the reason why it is so popular and unique in sealing field.

1 - Exceptional resistance to creep and cold flow

Because Expanded PTFE Gasket Sheet offers excellent tensile strength, so it keeps superb dimension stableness when it is in use both in thickness and width, compared to any other PTFE material gaskets.

Due to its thickness remains much more dimensionally steady than other types of PTFE material gaskets, Expanded PTFE Gasket sheet can conserve a higher percentage of bolt load in operation, delivering a bit more efficient seal particularly energy cycling and higher temperatures circumstances.

The width of Expanded PTFE Gasket Sheet also stays more dimensionally stable, staying away from gasket intrude in to the pipe bore which could negatively influence sealing result.

2 - Particularly reliable sealing performance

compression tests clearly show expanded ptfe gasket sheet is great at bearing the serious circumstances of industrial flange sealing. It shows a excellent overall performance of seal durability both at setting up and functioning at raised temps.

Expanded PTFE Gasket Sheet is actually resistant to most chemical compounds, it can still have excellent performance of sealing duration in robust alkali, strong acid and solvent-based procedure techniques. It withstands just about all mass media (pH 0-14) excluding molten, dissolved alkali metals and elemental fluorine.
