Kestamid (Polyamide)

What Is Kestamid?

Kestamid is also known as cast polyamide or cast nylon. Thanks to its superior mechanical, physical, chemical, and electrical properties, it is widely used across many industrial sectors as an engineering plastic.

Its very high molecular weight, crystalline structure, and cross-linked form make it hard, resistant to wear and bending, and less prone to water absorption than standard PA6.

Because it is produced by free casting and free cooling, Kestamid develops a crystalline molecular structure with very long cross-links and minimal internal stress. Compared with polyamides produced by extrusion or injection methods, cast polyamides can offer mechanical performance under heat and load that is two to three times higher.

By using production techniques specific to Kestamid, it is possible to manufacture parts such as gears with steel hubs, pulleys, mixer impellers, and cylinders with steel shafts. Special additive grades are also produced to further improve its already strong mechanical and physical properties.

Kestamid is yellow in color and has very good chemical resistance. It is not affected by solvents, oils, hydrocarbons, esters, or ketones, and it is resistant to acids and alkalis in the pH 5-11 range.

Main Application Areas: pulleys and gears with steel hubs, bushings, ship shaft and rudder bearings, plain bearings, wear pads, wear plates, wheels, slides, and rotating or sliding machine parts.

Non-standard Kestamid products can also be produced by us in requested sizes and dimensions.
