The KT PTFE are standard PTFE virgin/Unfilled and filled products for service temperatures ranging from cryogenic to 500ºF.

Widely used in many industries because of inertness and chemical resistance, as well as service temperatures from Cryogenic to 500F.


KT-1000: Unfilled PTFE and building block for many PTFE compounds. KT-1000 has the following characteristics: excellent all-round chemical resistance, widest service temperature range of -200 °C to +260 °C, superior dielectric properties, no embrittlement or ageing, very good non-stick properties, dimensional stability and stress cracking resistance.

KT-1025G: 25% fiber glass filled PTFE. Same chemical and thermal resistance as KT-1000 with improved compressive strength and lower CLTE for higher pressures. Excellent back up seal material, the wok horse of the PTFE filled products.

KT-2000G: 20% Carbon/Graphite filled PTFE. Excellent ductility, and wear resistance. Used primarily in wear applications in sliding and reciprocating motion. Ideal for Piston and Seal Rings for reciprocating compressors, aggressive environment seal and seats for valves.

KT-2005MO: 5% MoSO2 filled PTFE for dynamic sealing applications requiring lower wear than graphite filled PTFE. Molybdenum Disulfide imparts better wear performance than unfilled PTFE and exhibits greater deformation resistance.

KT-2015MO Data Sheet


KT-2015MG5MO: 5% MoSO2 for added strength and lubrication, 15% glass fiber added for improved deformation resistance. Can be used in more demanding applications than 25% glass filled PTFE or 5% MoSO2 filled PTFE. Ideal high pressure sealing material up to 500F.

The above PTFE compounds are just an example of the many PTFE products KT Plastics can produce in rod and tube from 1.0” diameter up to 12” in diameter, and tubes with OD/ID combinations ranging from 1.75 x 0.5 up to 24x 22 tube sizes as standard. Larger sizes can be made available for special projects.
