Kaxite Seals produces expanded PTFE spiral wound gasket filler material from 100% white virgin PTFE resin. It is a unique winding tape that will not age, harden, shrink or dry out in service, and stays unaffected by common industrial chemicals — so your finished gaskets keep the same sealing performance after years on the line.
If you run a spiral wound gasket production line and need a stable filler supply, this grade gives you ≥8 MPa tensile strength, working temperature from −268 °C to +280 °C, and a soft, flexible structure that conforms to rough or damaged flange surfaces. Custom width, thickness and roll length, OEM spool labels and flexible MOQ are available for B2B buyers.
Spiral wound gasket producers need a filler that behaves predictably on the winding machine, seals rough flange faces, and keeps its properties for years in the field. That is exactly what this grade is built for.
The tape will not age, harden, shrink or dry out in service — one less variable in your gasket winding process.
Kaxite Seals production noteThe filler is supplied in the standard width / thickness combinations below, with roll lengths from 5 m to 100 m. Custom widths up to 9.0 mm, non-standard thicknesses and cut-to-length strips are produced to your specification.

Width, thickness, roll length, quantity, working medium and destination port. If you have a drawing or sample, attach it and we will match it.
We reply with unit pricing, lead time and shipping options. Evaluation samples are available so your winding team can verify width, thickness and tensile strength first.
Choose neutral export cartons or private-label spool marking. We confirm pallet configuration and documentation before production starts.
Batch inspection covers width, thickness, tensile strength, density and PH. Inspection reports can be issued with the shipping documents.
Send your width, thickness, roll length, quantity and destination port. Our sales engineers reply with a quotation, available samples and the packing options for your market.
