DESCRIPTION
Kestamid® is also known as Cast Polyamide or Cast Nylon. Kestamid® is an engineering plastic used commonly in all industrial branches for its superior mechanical, physical, chemical and electrical properties. It is replacing aluminum, copper, bronze, steel, fiber, brass and other metals in many applications with superior advantages. It is cheaper, lighter, harder and more durable than these metals. In terms of cost, Kestamid® is 1/7th of bronze, 1/5th of copper and 1/3rd of brass.

As its density is low, purchase and delivery costs become less. Using Kestamid
® instead of metal components helps push selling price and delivery cost down. It contributes significantly to the final producer in reducing costs and increasing market share. As it does not require lubrication, maintenance costs are also reduced to a minimum. High wear and impact resistances make Kestamid® durable. Taking its operational life into consideration, the advantages and superiorities of Kestamid® compared to the above-mentioned metals become even more obvious. Kestamid® is a “fix and forget” type of material.

It is possible to produce steel bush core gears, pulleys and mixer fans or produce cylinders with steel axis by making use of techniques specific to the production of Kestamid
® combined with the mechanical resistance of metals.
