AI-Powered supplier vetting

SummaryQingdao New Sanda Industry Co., Ltd. is identified as both a trading company and manufacturer/factory in China, focused on chemicals and construction-related products. The supplier reports ISO-series management certifications, two production lines, 21–30 quality-control staff, and peak- and off-peak order fulfillment within 15 working days. Its stated capabilities include R&D, customized formulations, formulation optimization, application testing, troubleshooting, multilingual documentation, and after-sales support. The supplier reports extensive export coverage and began exporting in 2015, but the available trade evidence shows only one recorded transaction and one associated buyer. Financial credibility cannot be assessed because financial data is excluded from evaluation.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its stated business focuses on chemical products and industrial additives, including Titanium Dioxide, HPMC, VAE, HEC, CMC, and related materials.

CertificationsThe supplier lists ISO 9000, ISO 14001, ISO 9001, ISO 14000, and ISO 20000 certifications. These stated certifications provide explicit evidence of certified management-system coverage, although the slices do not provide certificate numbers, validity dates, or scope details.

After-Sales capabilityThe supplier states that it provides after-sales service, multilingual documentation, formulation optimization, application testing, and troubleshooting. These are explicit service offerings supporting customers after product delivery.

R&D capabilityThe supplier describes a dedicated R&D team, technical innovation, market-responsive product development, and feedback integration from global partners. It also reports total R&D engineer experience of 11–20 years, supporting an established innovation function.

Production capacityThe supplier presents itself as a chemical manufacturer and reports two production lines, 21–30 quality-control staff, and fulfillment within 15 working days in both peak and off-peak periods. Its product portfolio and end-to-end commercial supply description support production capability, although total output details are not evaluated here.

Customization capabilityThe supplier explicitly offers customized formulations for specific application challenges and provides formulation optimization, application testing, and troubleshooting. Its process includes sample testing through full-scale commercial supply, indicating support for tailored industrial additive solutions.

Product Q&A

Q:What is CBS used for?

CBS is a sulfenamide-type accelerator used to speed up vulcanization in natural and synthetic rubbers. It is widely used in tire treads, conveyor belts, hoses, shoe soles, and mechanical rubber goods.

Q:What is the recommended dosage?

Typical dosage is 0.5-2.0 phr. For tire tread compounds, 0.8-1.5 phr is common. The exact amount depends on rubber type, curing temperature, and desired performance.

Q:How does CBS compare to TBBS?

CBS offers slightly slower curing speed than TBBS but provides better scorch safety. CBS is more suitable for applications requiring longer processing time. TBBS is preferred for faster curing systems.

Q:Is CBS safe for use?

Yes, when standard safety measures are followed. Avoid dust inhalation and skin contact. Use protective equipment during handling. Follow normal industrial hygiene practices.

Q:Can CBS be used with other accelerators?

Yes. It is often used with DPG, TMTD, or other accelerators to optimize curing speed and improve physical properties. Compatibility varies by formulation, so testing is recommended.
