After the embargo on asbestos, PTFE products have been widely used as a replacement. This Is especially true in the chemical industry due to their excellent durability, but also in the food industry as they are FDA approved. ERIKS has been using Gylon® (Garlock) and Gore® products for many years.
|RX® Filled PTFE 150|
|High performance biaxially orientated sheet sealing material containing PTFE with hollow glass micro spheres. Excellent resistant against cold-creep and very gastight. Seals already with low bolt force. Universal chemical resistance and can be used for several flange materials: steel, plastic, glass and email.|
|RX® Filled PTFE 160|
|High performance biaxially orientated sheet sealing material containing PTFE with silica filler. Excellent resistant against cold-creep and very gastight. Universal quality for (petro-) chemical applications, acids and bases.|
|RX® PTFE||Pure PTFE pffers excellent chemical resistance. Recommended for a large variety of chemical products.|
GYLON 3501 datasheet (64kB)
|General purpose gasketing material offer significant advantages over pure PTFE in regard to higher temperature / pressure combination. Particularly suitable for use with strong acids (except hydrofluoric acid) and alkalis. Other applications include solvents, fuels, water, steam and chlorine.|
|Very high compressibility due to its inorganic micro spheres, thus sealing more effectively under lower bolt loads. Therefore extremely suitable for glass, ceramics, and plastic lined or distorted flanges and even flanges with light surface irregularities.|
The lowest gas permeability of all the PTFE range
GYLON 3510 datasheet (64kB)
|A general purpose grade for sealing applications across the whole pH- range. Particularly suitable for use with hydrofluoric acid and other strong chemicals such as potassium and sodium hydroxide, hydrogen fluoride, aluminium fluoride and chrome plating solutions .|
|GYLON 3545|| Pure PTFE with a highly compressible outer layer of microcellular PTFE and a rigid PTFE core. Designed for bad flange surfaces and low bolt loads. Has a high rigidity witch makes installation easier.|
|GORE GR||"Made from 100% expanded PTFE. Because it is dimensionally stable, yet conformable, it is ideal for real world flange conditions. It conforms to rough surfaces, yet compresses into a very tough gasket that makes a tight, long lasting seal.|
GORE-TEX GR® sheet gasketing is ideal for sealing steel flanges for many aggressive chemicals."
|GORE GR-R||Same as GOR GR with a rigid core made from pre-compressed expanded PTFE. Provides 6 times more rigidity.|
Tape / cord
|GORE DF||"Mono-directional expanded PTFE tape equipped with a self-adhesive tape a one side. Very low surface pressure needed. Can absorb big flange distortions."|
|RX® Flowtite||"Unidirectional expanded PTFE tape equipped with a self-adhesive tape a one side.|
Very low surface pressure needed. Can absorb big flange distortions."
|PTFE tape||100% expanded PTFE-tape, selfadhesive.|
|GORE Serie 300||"Multi-directional expanded PTFE tape equipped with a self-adhesive side.|
For steel flanges. Low stress needed."
|GORE Serie 600||"Multi-directional expanded PTFE tape equipped with a self-adhesive side.|
For steel flanges. Low stress needed."
|Eriflon Tape||Eriflon PTFE-thread tapes for general use, gas- and oxygen.|
|GORE UPG||"Universal Pipe Gasket. Made of expanded ptfe and an envelope of compressed ePTFE. The inside diameter is closed for a minimum diffusion.|
Best gas-tight gasket."
RX TEFMET datasheet (48kB)
|"Moulded PTFE ring with perforated stainless steel insert. Cold flow of ptfe is reduced to a minimum"|
|ENV-R||"Pure PTFE envelope with fibre gasket insert. Envelope with round nose. "|
|ENV-RD||Same as type ENV-R with thicker nose as diffusion barrier.|
|ENV-H||"Pure PTFE envelope with fibre gasket insert. Envelope with straight nose. "|
|ENV-HD||Same as type ENV-H with thicker nose as diffusion barrier.|
|ENV-V||"The ptfe envelope is cut without waste. Give a more cheapest type than all the others."|
|ENV-SS-R||"Large PTFE envelope with round nose. Inserts are a corrugated stainless steel core with two fibre based insert. Specially designed for glass lined reactors like Pfaudler or De Dietrich"|
|ENV-SS-RD||same as ENV-SS-R with a thicker nose for less gas diffusion.|
