Testing Before Shipping, Not After a Claim Temperature · pH · API 622 Leakage · Fiber Diameter · Shot Content
Mineral fiber packing performance is determined by fiber grade, impregnation, and braid density. Those are measurable variables — and Kaxite measures them on each production lot before dispatch, so the report matches the batch, not the catalog.

Impregnation & Fiber Grade Development
PTFE, graphite, and oil impregnations cover most pump, valve, and static high-temperature duties. For aggressive media, high-temperature service, or specific friction targets, the lab evaluates the impregnation and fiber grade against the buyer's operating envelope.
-
PTFE dispersion for chemical resistance and low friction
-
Graphite for thermal stability and static joint sealing
-
Oil for asbestos grades in steam and hot water
-
Fiber grade review for temperature, pH, and dynamic limits
What the Buyer Receives
For each qualified specification, the buyer can receive test data tied to the production batch, not a generic catalog value. This matters when the packing goes into a documented maintenance or shutdown scope.
-
Batch-level test report with measured values
-
Link to MTR and EN 10204 3.1 certificate when specified
-
Technical data sheet with temperature, pressure, and pH limits
-
Impregnation and grade notes for repeat orders
Have a specification that standard mineral fiber packing cannot meet?
Send the operating conditions and the lab team will review the grade and impregnation route.
