KT/KTL Series

The KT/KTL series are PTFE (Polytetrafluoroethylene) Micropowders which provide low-friction and wear-resistance.

The KT/KTL series drastically reduce the friction coefficient and wear, and improve the PV value when added to thermoplastics and thermosetting plastics, rubbers, elastomers. Also the KT/KTL series can add performances such as stain resistance, non-stick, water/oil repellency.

The KT/KTL series(especially, the high molecular weight grades of KT series) do not flow or thermally decompose at temperatures above the melting point. Therefore, they can be added to every kind of plastics molded over 400 ?C.
