TSP(Thermally Stable Polycrystallin)


Sinoseiko located in Zhengzhou——The biggest diamond industrial area in the world. Cooperated with outstanding manufactures and the most advanced TSP(Thermally Stable Polycrystallin) test lab in China. This enables Sinoseiko to provide our customers with practical solutions for their TSP(Thermally Stable Polycrystallin) needs.

Thermally Stable Polycrystalline (TSP) is thermally stable polycrystalline diamond product, which is manufactured by the same ultra-high pressure and high temperature techniques associated with other PCD products. Its binder is chemically inert and has a similar coefficient of thermal expansion to that of diamond. It is thermally stable up to 1200 degree Celsius. It can be manufactured into a variety of sizes and shapes (Cubes, Cylinder, Rectangles, Triangles, etc.)


One of the primary applications for TSP is wear protection on the gage of drill bits, It is suitable for oil drilling bits and mining bits, and can be used as a primary cutting element, in some cases.


1. Sinoseiko can supply TSP with the highest performance and the greatest value.

2. Sinoseiko TSP is proven in laboratory and field testing that suitable for gage of oil drill bits and mining drill bits.
