AI-Powered supplier vetting

SummaryDongguan Huadai Silicone Co., Ltd. is a China-based silicone rubber supplier established in 2017, described as a manufacturer integrating R&D, production, and sales. Its stated product scope includes solid, mixing, compound, HTV, RTV2, precipitation, gas-phase, flame-retardant, electrically insulating, and other specialty silicone rubbers. The supplier reports a 65,000 m² plant, nine production lines, 80,000 tons of solid silicone rubber annual output, and 138 employees. It holds ISO 9001:2015 certification and reports export activity, including self-operated import and export rights. Evidence supports substantial production capacity and a broad product portfolio. However, the provided information is insufficient to verify after-sales processes, financial credibility, detailed customization procedures, or specific customer cases. Some workforce information is inconsistent: one slice states two R&D engineers, while another states eight silicone researchers.

Supplier typeThe supplier is identified as Dongguan Huadai Silicone Co., Ltd., a China-based limited company established in 2017. It is described as a manufacturer integrating R&D, production, and sales, although one record categorizes the company nature as a trading company and another labels the business entity as combined.

CertificationsThe supplier explicitly reports holding an ISO 9001:2015 management-system certificate. No other certifications are provided in the available slices.

R&D capabilityThe supplier describes R&D and product innovation as strategic priorities and offers multiple specialized formulations, including flame-retardant, electrically insulating, ceramic, platinum-vulcanization, and double-24-vulcanization silicone rubbers. However, the slices contain inconsistent R&D staffing information—two R&D engineers in one record versus eight high-tech silicone researchers in another—so the scale of innovation resources is not fully clear.

Production capacityProduction capability is supported by a 65,000 m² plant, nine reported production lines, stated annual solid silicone rubber output of 80,000 tons, and a product portfolio covering multiple silicone-rubber categories. Another description mentions 18 sets of compounding equipment, but this differs from the nine-line figure and should be clarified.

Product Q&A

Q:What is Self-Adhesive Liquid Silicone Rubber (LSR)?
