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 a microsphere blowing agent used for?

It is used to create lightweight, foam-like structures in various materials. It expands upon heating to form closed-cell spheres, providing weight reduction, cushioning, insulation, and unique surface textures.

Q:How does it work?

The shell softens when heated, and the internal hydrocarbon gas expands, increasing the volume by 40-80 times. After cooling, the expanded structure remains stable.

Q:What are the expansion temperature options?

Available in different grades: low (below 110C), medium (110-160C), high (160-220C), and ultra-high (above 220C). Choose based on your processing temperature.

Q:Is it safe to use?

Yes. It is non-toxic, odorless, and VOC-free. It contains no harmful residues, making it suitable for high-end and environmentally friendly applications.

Q:What is the recommended dosage?

Dosage depends on the application. For lightweighting, typical use is 1%-5% of total formulation. For surface effects, lower dosages may be sufficient. Testing is recommended.
