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 are hollow glass microspheres used for?

They are lightweight filler materials used in coatings, plastics, composites, drilling fluids, and insulation materials to reduce weight, improve insulation, and enhance performance.

Q:Can they withstand high pressure?

Yes. Depending on the grade, they can withstand pressures from 1,000 psi to over 10,000 psi. High-strength grades are suitable for deep-well drilling and underwater applications.

Q:What is the typical particle size range?

Particle sizes range from 10 to 120 microns, depending on the specific grade. Standard grades like HL20 have D50 around 50-60 microns.

Q:Are they compatible with various resins?

Yes. They are compatible with polyester, epoxy, polyurethane, acrylic, and other resin systems. Their surface treatment ensures good bonding with most polymer matrices.

Q:How much weight can they save?

Weight reduction of 15%-45% is achievable depending on filler loading and density. They effectively lower overall composite density without sacrificing strength.
