AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier focused on refractory materials and related building-material products. It supports sample-based, design-based, full, minor, and flexible customization, and reports five production lines, inventory capability, valid manufacturing contracts, quality assurance, and raw-material traceability. ODM and OEM services are available, including cooperation with Fortune 500 companies and a reported repeat-buyer preference of 80%–100%. However, the supplier does not provide 3D software design, has no SDK, no overseas warehouse, showroom, agents, or branches, and has not participated in offline trade shows. Service procedures for supplier assessment, corrective actions, and complaints exist but lack written records. Certification status, after-sales capability, detailed financial credibility, and independently verifiable customer-case details remain insufficiently documented.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier. Its stated business scope covers production and sales of refractory materials, building materials, lightweight building materials, and cement products, as well as import and export activities.

After-Sales capabilityThe supplier reports no overseas warehouse, showroom, overseas agents, or branches, and offers overseas services in zero countries. It has complaint-handling and corrective/preventive-action procedures, but no written records, so after-sales capability is only partially evidenced and has clear overseas-service limitations.

Production capacityProduction capability is supported by five production lines, valid manufacturing contracts with affiliated subcontractors, in-stock capacity, equipment for testing and screening, and a finished-product inspection procedure that is instructed and uniformly followed. Peak- and off-season lead times are both within 15 working days, although the supplier-assessment procedure lacks records.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its ODM capability and professional technical positioning further support customized product development, although 3D software design is not available.

Client casesThe supplier reports OEM service for well-known brands, cooperation with Fortune 500 companies, and a repeat-buyer preference of 80%–100%. These statements indicate relevant customer experience, but no customer names, project descriptions, or independently verifiable case details are provided.

Product Q&A

Q:What are cenospheres and where do they come from?

Cenospheres are hollow silicate micro-spheres extracted from the fly ash of coal-fired power plants. They typically appear in white or light gray.

Q:What is the particle size range of these cenospheres?

The cenospheres range in size from 20 to 500 microns, providing excellent fluidity and ease of use in various applications.

Q:Are cenospheres chemically stable?

Yes, their alumina silicate composition ensures integrity in water, organic chemicals, acids, alkalis, and other solvents.

Q:How does the strength of cenospheres compare to other materials?

Cenospheres are three to ten times stronger than most man-made hollow glass spheres, providing higher compressive strength due to their robust outer shell.

Q:What customization options are available for density and color?

Density can be customized from 0.75 to 0.95 g/cm3, and color options include grey. Other parameters like pH and SiO2 content are also adjustable.
