AI-Powered supplier vetting

SummarySIDLEY CHEMICAL CO., LTD. is a China-based limited company established in 2005, operating in Shandong and supplying construction chemicals. The supplier reports broad customization and ODM capabilities, recent new-product development, and OEM service for recognized brands. It has documented procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaints. Production information indicates two production lines, 6–10 quality-control staff, and stated capacities for several cellulose, polymer, and calcium-formate products, although the capacity figures differ between sources. Overseas service coverage is limited: the supplier reports no overseas warehouse or showroom, but does have overseas agents or branches and has participated in the Eurocoat Exhibition. Financial credibility cannot be determined from the provided slices because the records identify years but provide no assessable financial results. Certification status and customer cases are also not...

Supplier typeThe supplier is identified as a combined company and a limited company, with SIDLEY CHEMICAL CO., LTD. as its English name. It is located in Linyi, Shandong, China, and is not identified as an offshore company.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints and for corrective and preventive actions. It offers overseas services in Pakistan through overseas agents or branches and supports stated quotation and payment terms, but has no overseas warehouse or showroom.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services, supported by four R&D engineers. However, it reports no available SDK, and the slices do not provide detailed innovation results, patents, or development metrics.

Production capacityThe supplier reports two production lines, 6–10 quality-control staff, and substantial stated capacities across RDP, HEC, HPMC/MC, sodium carboxymethyl cellulose, and calcium formate. The capacity descriptions in the two slices are not fully consistent, so the existence of multi-product production capability is supported, but the exact capacity level requires verification.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, indicating a broad stated ability to adapt or develop products to customer requirements.

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.
