Global sales and operations center for HEC, HEMC, HPMC cellulose ethers.
Zhiwei (Jinan) New Materials Co., Ltd. supports overseas customers with product selection, sampling, and order execution. Manufacturing and shipment are managed by our Zhejiang head office and production base. We focus on clear communication, stable supply, and practical technical support.
The Jinan team connects your needs with factory production. We help you choose the right grade, confirm performance by sampling, and keep orders moving on schedule. When formulas change, we respond with clear next steps.


Our Zhejiang plant runs modern cellulose ether lines with automated control. We use refined cotton as a key raw material. We manage fineness, viscosity, ash content, and light transmittance to keep performance stable from batch to batch.
We supply Hydroxyethyl Cellulose (HEC) and Hydroxyethyl Methyl Cellulose (HEMC) and Hydroxypropyl Methylcellulose (HPMC) for a wide range of applications. Typical uses include dry-mix mortar, tile systems, wall putty, and water-based coatings. Share your targets and process. We will recommend grades that fit your production needs.


We run routine tests to keep batch consistency. Common controls include viscosity, fineness, moisture, ash content, and appearance. We can provide COA by batch. We also support sample testing when you develop new formulas.
Stable output depends on stable site operations. We keep clear safety signage, emergency response maps, and routine inspections. Environmental management is treated as a daily requirement.
