Dear Business Partner
It is our top priority to serve you in the best possible way, despite the current turbulences with the Corona virus. I therefore want to give you an update on the status of the Sefar Group, which also includes Monosuisse.
• The Sefar Group complies to all the local regulations with respect to the containment of the Corona virus.
• We have taken additional internal precautions to assure the continuation of our production and the deliveries to you.
• All of our spinning and weaving plants worldwide are currently operating without limitations.
• There is a possibility of national restrictions in countries, where we operate our decentralized fabrication units. This may cause delays in fabricated items. For details, please contact your local Sefar subsidiary.
• Global limitations on freight capacity, in particular for air shipments, may also affect the delivery time.
Being a fully integrated supplier, Sefar controls and ensures the entire supply chain of our technical fabrics, from the yarn production at Monosuisse to the shipping of the fabrics or the finished articles. You are in good hands at Sefar.
Should your operation face any supply challenges where we might be able to help, please let us know. Your contact person is reachable at any time.
We will keep you updated on any changes affecting our delivery performance.
I wish you good health!
Fabrics, single and multilayer, can be heat-slit into tube configurations. Tubes are made by slitting two layers of fabric together with a heated knife, creating two flat seams at either side of the tube. Heat-slit fabric edges are melted or fused together to increase durability and to decrease fraying. The heat-slit seam has a limited strength and should be used as a transport seam only, e.g. for injection molding.
All fabrics with thread diameters < 250 µm and mesh openings < 500 µm can be heat slit
Heat-slit tubes are specified by having a defined inner diameter. Diameters range from 6 to 320 mm
The inner diameter of the heat-slit tube does not equal the flat width of the tube itself. The effect of welded 'wings' on either side has to be taken into consideration. The width depends on the mesh type
Ultrasonic flat-welded tubes 2 – 168 mm for fabrics up to 500 µ
Tubes are wound onto standard cores (polyester discs) which have an inner square hole of 30 x 30 mm and an outer diameter of 61 mm
Upon request tubes can also be rolled onto ABS rings with a inner diameter of 76 mm (3").
Depending on fabric type and tube dimensions, roll length of up to 500 m are possible.
Fabrics, single and multilayer, can be ultrasonically welded into tube configurations. Tubes are made with one overlapping ultrasonic weld. Welds are accurate, clean and are made without the introduction of secondary material to the weld.
Tubes, cut to length, are segments cut from woven, ultrasonically welded or heat-slit tubes.
Tube segments are packed into PE bags that are sealed
Tube segments made of SEFAR MEDIFAB fabrics are
