About Us
About Zhongzhi Chemical Technology
Shandong Zhongzhi Chemical Technology Co., Ltd. is a sodium metasilicate manufacturer in Changyi, Shandong, China. We sell factory-direct and have been exporting for 10+ years, with customers worldwide. Grades supplied are anhydrous and pentahydrate sodium metasilicate, plus instant sodium silicate powder.
Founded in 2011, the company has grown from a general inorganic-silicate producer into a focused sodium metasilicate specialist. It operates a registered 100,000 MT annual silicate capacity, holds ISO 9001:2015 and ISO 14001 certificates (REACH regulatory documents are available for review on request), and ships in 25 kg bags, FIBC jumbo bags and bulk with COA, SDS and TDS on every order, as a direct factory, not a trading desk.
Its operating principle is consistent, traceable supply: every grade ships against a published specification and a batch-specific COA, so a qualified buyer receives the same material shipment after shipment. That predictability — not the lowest headline price — is what its long-term OEM and distributor relationships are built on.

Process Overview
From raw material to packed finished product, in four connected stages.
Raw Material Storage
Bulk raw materials stored on site; different materials are handled separately.
See raw-material storage →Mixing, Milling & Conveying
Mixing tanks, rotary drum milling and conveying move material through the process, shown in the equipment below.
