AI-Powered supplier vetting

SummaryThe supplier operates across chemical products, machinery, building materials, medical devices, protective products, information security, and related categories. It reports ISO 9001 certification, a quality assurance measure, 50 quality-control staff, Shanghai-based facilities, and export markets in Southeast Asia, the Middle East, and Europe. However, documented service-management procedures, complaint-handling records, overseas service infrastructure, offline trade-show participation, ODM/OEM services, SDK availability, and customer cases are absent or explicitly unavailable. Production lead time is stated as one month in both peak and off-peak periods. Financial information is inconsistent and insufficient for a reliable credibility assessment.

Supplier typeThe supplier presents itself as a diversified manufacturer and trading/service supplier covering chemicals, machinery, building materials, medical devices, protective products, information security, and related products. Its stated core products include nano hydrophilic silica and synthetic resin, while its Shanghai location and production-related information support a supplier role rather than a purely commercial intermediary.

CertificationsThe company description explicitly states that the supplier is ISO 9001 Quality Management System certified. This is direct evidence of holding a recognized quality-management certification.

After-Sales capabilityThe supplier states that it has quality assurance, but reports no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. It also has no overseas warehouse, showroom, agent or branch, and no offline trade-show participation, although it accepts multiple quotation and payment terms and states a one-month lead time.

Production capacityThe supplier describes production optimization and a product portfolio spanning chemicals, machinery, building materials, medical devices, and protective products. It reports a Shanghai factory location, 50 quality-control staff, nearest-port access through Shanghai, Ningbo, and Qingdao, and a one-month lead time in both peak and off-peak periods; however, the stated annual output information is not sufficient to establish production scale across all listed categories.

Customization capabilityThe supplier explicitly states that it does not provide ODM services and does not provide OEM services for popular brands. No broader customization capability is documented, indicating a clear limitation for branded or design-led customization.

Product Q&A

Q:What is the product name and appearance?

The product is White Carbon Black (Silica). It appears as an amorphous white powder, available in packaging sizes of 10kg, 15kg, or 25kg.

Q:What are the main advantages of this silica?

It offers excellent rheological properties, improves product dispersion, and provides anti-settling and anti-sagging performance. It also enhances mechanical strength, whiteness, and reduces weight per unit area when used as a paper filler.

Q:How does it improve rheological properties?

When used as a paper filler, it increases the paper's resistance to ink penetration, boosts mechanical strength, improves whiteness, and reduces basis weight. In coatings, it controls rheology, prevents sagging, improves leveling, and increases scratch resistance.

Q:What does 'improve product dispersion' mean?

The silica particles have small particle size, large specific surface area, and strong surface adsorption. This helps evenly disperse other ingredients in formulations, strengthens paint film adhesion, and improves overall product consistency.

Q:Does it help with anti-settling and anti-sagging?

Yes. During storage, the silica provides anti-settling and anti-sagging properties. It also enhances edge coverage control. In varnishes, it delivers high gloss, rheology control, anti-sagging, leveling, and scratch resistance.
