Flat gaskets made from Dyneon material, e.g.: TFM4105
Flat gaskets made from TFM™ (modified PTFE) are high quality gaskets which are mainly used in the chemical and food industry.
The gaskets have also proven themselves regarding eco-friendliness, health considerations and due to their excellent handling.
The almost universal resistance against chemicals and solvents is another special feature of these gaskets.
Excellent properties in comparison to non-modified PTFE are the considerably reduced deformations under load even at increased temperatures and the reduction of the gas and vapour permeability due to a less porous homogeneous structure.
Basis material for the flat gasket is TFM™ 4105 from Dyneon (formerly Hoechst). It is a compound which consists of modified, hence cold flow reduced PTFE with a glass fibre fraction of 25%.
Basic material for the flat gasket is the modified cold flow reduced TFM 1600 by Dyneon. The gasket also has an inner and outer eyelet (1.4571). This encloses the PTFE when installed and prevents a pressing out in the tongue and groove area.
Basic material for the flat gaskets is the modified cold flow reduced TFM™ 1600 by Dyneon.
The flat gasket/seal plate is made of pure virginal PTFE, a cost-favourable alternative for use
Basic material for the flat gasket is the pure PTFE powder TF 1620 by Dyneon.
Basis material for the flat gasket is TF 4105 from Dyneon (formerly Hoechst). It is a compound which consists of pure PTFE with a glass fibre fraction of 25%.
PTFE - UNIFLUOR flat gaskets
The universal flat gasket material allows pressure / temperature combinations which are beyond those of pure or fibre reinforced PTFE.
The materials have high elastic recovery strength as well as a good chemical resistance. (resistance is slightly limited due to the filler).
Good sealing properties are achieved even at low surface compression.
UNIFLUOR WS 7550 is a high quality biaxially orientated sealing material on PTFE basis, filled with hollow micro glass balls.
UNIFLUOR WS 7551 is a high quality biaxially orientated sealing material on PTFE basis, filled with quartz.
UNIFLUOR WS 7553 is a high quality biaxially orientated sealing material on PTFE basis, filled with barium sulphate.
Flat gaskets made from ePTFE (multi-directional stretched)
Flat gaskets made from IDT-UNIFLUOR® - ePTFE consists of virginal, stretched PTFE.
The special manufacturing process creates the multi-directional fibre structure which gives those seals the special properties.
Flat gaskets made from ePTFE stand out especially due to their very low setting properties and the negligible low increase in width even in the most extreme conditions.
Die-cut gasket made from multi-directional stretched ePTFE
The basic body of the gasket consists of virginal PTFE of low density with a multi-directional fibre structure. It also has an inner eyelet from almost porous-free modified PTFE in high density (Dyneon ™ TFM™). Additionally the outer area is pre-sealed.
