CHDM 1,4- cyclohexanedimethanol Supplier: EASTMAN typical properties table properties typical molecular formula C8H16O2 144.21 equivalent (theory) 72.1 hydroxyl value (100% solids) 778 Appearance white waxy solid color Pt-Co ≤10 ( melting) ≥98.5wt% moisture content ≤0.2 wt% melting temperature 41-61 ℃ freezing point 24 ℃ Boiling point 284-288 ℃ 1.02 specific gravity structure / property relationships of polymer hydroxyl groups characteristic structural features performance level and not blocked very fast synthesis, crosslinking temperature is lower or reduce the time symmetry excellent thermal stability, light-colored resin saturated cyclic structure is very good hardness and a certain flexibility 1,4-substituted structure is very high glass transition temperature (Tg), Medium The solubility of β-bit hydrogen moderate weather resistant synthetic Tips ■ Because the water-soluble segregation need to fill column. ■ CHDM molten material within the vessel, and stirred until samples were taken in order to ensure a homogeneous mixture of isomers. ■ As good thermal stability, even if the synthesis temperature of 230 ℃ ~ 240 ℃ can be obtained colored resin. ■ two primary hydroxyl groups provide good reactivity and moderate synthesis time. ■ No need esterification catalyst, but can also be used. Applications: Thermal layer coating resins chemicals and pharmaceutical intermediates cosmetic polymer intermediate polyurethane coating polyester polyol with melamine (melamine) polyester baked porcelain cosmetics and personal care products unsaturated polyester resin aqueous solvent polyester Resin IV. Main features: saturated polyester Coatings: Excellent hardness and accompanied by some of the synthetic resin and curing process flexibility phase for linear aliphatic diol has a very high glass transition temperature (Tg) hydroxy high reactivity, the reaction speed, the reaction temperature is low. Application of the unsaturated polyester resin product: excellent heat resistance and electrical properties, particularly for the synthesis of unsaturated polyester resin glass fiber reinforced sheet molding compound SMC. Very high crystalline granular injection molding can be used. Synthetic glass fiber reinforced plastics have excellent corrosion resistance
