Calcined kaolin

Wednesday, 27 October 2010
Dear Spurtle,

Very glad to contact you!

Datong Coal Industry Jinyu Kaolin Chemical Co., Ltd.  is one of the largest professional manufacturer of calcined kaolin (Anhydrous Aluminum Silicates) in China.  The total investment capital is 230 million and annual capacity of two superfine-calcined kaolin 6250 meshes and 4000 meshes amount to 70,000mt. Please browse our company website for more information.

Our calcined kaolin (GB-CK90, GB-CKR90, GB-CK88A  are recommended), a functional additive, is widely used in wire and cable, especially in EPDM cable. PVC and PE colophony are applied in common wire and low-tension cable (1-2KV) jacket material and no extender is needed but for fire retardation. Sometimes calcium carbonate is added to lower costs and improve dielectric property.

High-tension jacket is mainly made up of EPDM and XLPE. And XLPE needs no extender. EPDM, which represents 90% share of the industrial market, has higher requirement for cable's physical and mechanical properties, and it needs high-quality extender to meet the application requirement. Our modified calcined kaolin series is specially applied in EPDM wire and cable as functional extender. After being resurfaced particularly, it can strengthen the insulating, mechanical and other properties of wire and cable. And it is an excellent functional additive in EPDM cable because of its unsurpassed performance.

Best wishes,

Duan Yunjie
