Colemanite (B-11%) (CAS NO : 1318-33-8)

Hydrated calcium borate CAS 1318-33-8 serves as a pivotal high purity fine chemicals source for the production of heat-resistant borosilicate glass and fiberglass, maintaining a standard 98% purity for the glass industry. Calcium borate pentahydrate is increasingly utilized as an effective synergist in halogen-free flame retardant (HFFR) systems for polyolefin-based cable compounds and bituminous roofing, where its endothermic decomposition at 330 degrees Celsius acts as a critical heat sink. Natural dicalcium hexaborate pentahydrate remains a strategic mineral in the API intermediates market for downstream synthesis of boron-based pharmaceuticals and disinfectants, reflecting a global sourcing shift toward high-yield Turkish reserves to ensure reliable bulk chemical supplier chains. As globally established Colemanite supplier, we ensure dependable supply, consistent quality, and complete regulatory documentation, including CoA and TDS across all grades. Beyond supply, we support partners through the entire product lifecycle from route scouting, process and formulation development, and analytical method development to scale-up, process optimisation, and pilot-to-commercial manufacturing. Our teams also assist with GMP-compliant quality assurance, regulatory documentation, and global supply chain and logistics coordination.
