2,2,4,4-Tetramethyl-1,3-cyclobutanediol CBDO CAS 3010-96-6

• • • • • • ✅ Ultra-high purity 99.91%, far exceeding the ≥98.0% industry standard: Extremely low residual impurities, effectively reduces side reactions during polymerization, ensures uniform molecular weight distribution, and guarantees stable optical and mechanical properties of finished polymers.
          • ✅ Ultra-narrow melting point range 127.9-128.9℃, strictly within 126.0-129.0℃ specification: Narrow melting range indicates high crystallographic uniformity and excellent batch consistency, enables precise temperature control during melting processing, and fits continuous industrial polymerization production perfectly.
          • ✅ White crystalline powder with excellent appearance: No chromatic aberration and no heavy metal impurities, will not cause yellowing of polymer products, especially suitable for high-transparency optical grade and food contact polymer formulations.
          • ✅ Unique alicyclic ring structure: Tetramethyl cyclobutane skeleton endows polymers with higher glass transition temperature, outstanding thermal stability, chemical resistance and impact resistance, far superior to conventional linear diols.
          • ✅ BPA-free safe monomer: Non-toxic and environmentally friendly, does not contain bisphenol A structure. Polymers synthesized from CBDO comply with food contact material standards, suitable for infant products and food packaging applications.
          • ✅ Excellent weathering and hydrolysis resistance: The rigid alicyclic structure improves the weather resistance and hydrolysis resistance of polyester resin, extends the service life of outdoor coatings and engineering plastic products.
          • ✅ Wide formulation compatibility: Can be copolymerized with terephthalic acid, ethylene glycol, neopentyl glycol and various polybasic acids / diols, flexible to adjust polymer hardness, toughness, heat resistance and processing performance.
          • ✅ Multi-scenario application versatility: Suitable for high-performance copolyester, powder coating resin, engineering plastic modification, specialty adhesive, optical material and other high-end fields, a high value-added fine chemical monomer.
          • ✅ Strict batch quality control: Each batch is tested for full indicators including assay and melting point, accompanied by official COA, supports quality verification for import customs clearance and factory incoming inspection.
          • ✅ Stable bulk supply capacity: Mature production process, stable output and reliable quality, can support long-term stable supply for R&D and mass production of high-end polymer customers.
