Import Bisphenol A-Glycidyl Methacrylate (Bis-Gma) — Buy in Bulk from Supplier in China

Bisphenol A-Glycidyl Methacrylate (BIS-GMA), CAS 1565-94-2, is a dimethacrylate monomer widely adopted in dental restorative materials for its ability to cross-link and form durable polymer networks. This compound from Hebei Tianao Technology Co., Ltd exhibits high viscosity, ensuring controlled flow during precision dental applications such as composite fillings and adhesive bonding. Its chemical structure combines the bisphenol A backbone with glycidyl methacrylate groups, delivering compatibility with light-curing systems and resistance to oral fluids.

The material is engineered for biocompatibility, meeting dental-grade safety standards for intraoral use. Typical BIS-GMA formulations achieve a refractive index of approximately 1.55, closely matching that of natural tooth enamel for aesthetic integration. Industry-standard BIS-GMA also demonstrates low volumetric shrinkage upon polymerization, typically under 2.5%, reducing microleakage risks in restorations. The compound’s thermal stability, standard up to 150°C, ensures reliability during autumnal and curing processes in dental labs.

Dental laboratories and practitioners source BIS-GMA for composites, bonding agents and sealants, particularly where long-term mechanical strength and colour stability are required. Buyers confirm trade terms directly with Hebei Tianao Technology Co., Ltd, as lead times, MOQ and packaging formats are not specified in the listing. The product’s primary applications include anterior and posterior restorations, where its light-curing capability supports rapid chairside procedures.

Hebei Tianao Technology Co., Ltd is a China-based supplier of specialty chemicals, including dental-grade monomers such as BIS-GMA. The company operates within the imported supplier tier, indicating it sources or distributes products for international markets. Its profile does not specify a physical address, production capacity, or certifications beyond the product’s stated compliance with dental safety standards.

The supplier’s response rate and average response time are currently unavailable, suggesting buyers should expect to initiate contact directly for trade inquiries. No additional details are provided about the company’s history, facility size, or client base, so verification of its capabilities and quality control processes should be conducted prior to ordering.
