AI-Powered supplier vetting

SummarySIDLEY CHEMICAL CO., LTD. is a Chinese limited company established in 2005, operating in Shandong and focused on construction chemicals. The supplier reports customization and ODM capabilities, recent new-product development, OEM service for well-known brands, and documented procedures for supplier service capability, corrective and preventive actions, and customer complaints. Production information indicates two production lines and substantial stated capacities across cellulose products, redispersible polymer powder, and calcium formate, although the reported capacity figures differ between slices. Overseas service support includes agents or branches and participation in the Eurocoat Exhibition, but no overseas warehouse or showroom is reported. Financial records are identified for 2023–2025, but no usable financial performance details are provided. A BV audit is listed with validity from April 20, 2026 to April 19, 2027 and an evaluation result of 0; the meaning of this result is not explained.

Supplier typeThe supplier is identified as a combined company and a limited company, with its headquarters and operations in Linyi, Shandong, China. It is not identified as an offshore company.

After-Sales capabilityThe supplier reports written procedures and records for service capability assessment, corrective and preventive actions, and effective customer-complaint handling. It also supports overseas services through agents or branches and offers service coverage in Pakistan, but it has no overseas warehouse or showroom.

R&D capabilityThe supplier states that it developed new products during the past year and provides ODM services, while reporting four R&D engineers. It does not have an available SDK, but the available evidence supports product-development capability.

Production capacityThe supplier operates two production lines and reports product capacities including 10,000 tons each for RDP, HEC, and sodium carboxymethyl cellulose, 30,000 tons for calcium formate, and 20,000 tons for HPMC. A separate company description reports different annual capacities for several products, so production capability is evidenced but the figures are not fully consistent.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, demonstrating broad stated customization coverage.

Product Q&A

Q:What is the main difference between HEMC and HPMC?

HEMC contains hydroxyethyl and methoxy groups, while HPMC contains hydroxypropyl and methoxy groups. HEMC has more hydrophilic groups, resulting in a higher gel temperature and better thermal stability.

Q:Why is HEMC recommended for high-temperature applications?

HEMC maintains water retention and thickening effects at higher temperatures where HPMC might lose viscosity. It ensures better work performance and bonding strength in hot summer weather.

Q:What are the recommended applications for HEMC?

It is recommended for tile adhesives, thick plastering mortars, and light render plasters that require anti-sagging properties and high-temperature stability.

Q:What is the purity and raw material of this product?

The product has a purity of 99% and is made from cotton as the raw material.

Q:Does the manufacturer offer free samples?

Yes, samples can be freely provided for customers to test the product quality.
