Polycaprolactone(PCL)
Polycaprolactone is an organic high molecular polymer with the chemical formula (C6H10O2)n. It has the property of being well soluble in aromatic compounds, ketones and polar solvents. It is produced by ring-opening polymerization of ε-caprolactone in the presence of metal organic compounds (such as tetraphenyltin) as catalyst and dihydroxy or trihydroxy as initiator. It belongs to polymerized polyester, and its molecular weight and disproportionation degree vary with the type and amount of s...Read more -
Polyester Polyols
Polyester polyol is an important raw material for synthesizing polyurethane. It plays the role of a flexible soft segment in polyurethane synthesis, while isocyanate and small molecule chain extender constitute the hard segment of polyurethane. Since Chemicalbook polyester polyol affects the soft segment polarity and soft and hard aggregation structure of polyurethane elastomer molecules, the type, structure, number average molecular weight, etc. of polyester polyol have a great influence on ...Read more -
Polymer Polyol(POP) POP 2045
Application Polymer polyol (POP) is a kind of vinyl monomer or several kinds of vinyl monomers in situ polymerized with basic polyether polyol as continuous phase. As a bulk industrial product, it can give polyurethane products good load-bearing performance and improve the open-cell chemical book of foam. It has excellent physical and chemical properties and is widely used in the preparation of high-resilience and high-load polyurethane soft and semi-rigid foam plastics and elastomers, etc. I...Read more -
Soft foam polyether(F2 3000Da,F4 3500Da)
Polyether polyol (abbreviated as polyether) is an organic polymer, which is obtained by polyaddition reaction of initiator (compound containing active hydrogen group) with ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO) etc. in the presence of catalyst. The largest polyether production is produced by using glycerol (glycerol) as initiator and epoxide (generally PO and EO are used together). By changing the feeding method of PO and EO (mixed or separate), feeding ratio, feeding ...Read more -
High resilience foma(F1 6000Da,F3 4800Da,F5 3000Da)
聚醚多元醇（简称聚醚）是一种有机聚合物，是由起始剂（含活性氢基团的化合物）与环氧乙烷（EO）、环氧丙烷（PO）、环氧丁烷（BO）等在催化剂存在下经加聚反应制得。聚醚产量最大者为以甘油（丙三醇）作起始剂和环氧化物（一般是PO与EO并用），通过改变PO和EO的加料方式（混合加或分开加）、加量比、加料次序等条件，生产出各种通用的聚醚多元醇。Read more -

3,5,5-Trimethylhexanoyl chloride
Preparation: Add isononanoic acid (300 g, 1 eq.) to a 500 mL reaction bottle, and introduce phosgene (1-5 eq.) at a certain temperature and a certain speed, and monitor the reaction process by gas chromatography. After the reaction is completed, dry nitrogen is introduced into the reaction mixture to replace the unreacted phosgene, by-product carbon dioxide and hydrogen chloride, and then 3,5,5-trimethylhexanoyl chloride is obtained by vacuum distillation as a colorless liquid.Read more -
Biphenyl
Biphenyl, also known as phenylbenzene or biphenyl, is a compound formed by two phenyl groups connected together. The pure product is white or colorless to light yellow flaky crystals, while the industrial product is slightly yellow with a special aroma. Melting point 69.2℃, boiling point 255.2℃. It is insoluble in water but soluble in organic solvents. It is often used as a precursor for organic synthesis and is one of the main components of organic high-temperature heat carriers. Derivatives...Read more -
Formic acid
Formic acid is an important chemical raw material. It was first discovered by Fisher in 1670. A.S.Marggret first produced pure formic acid in 1749. It was named formic acid because it was first discovered by distilling red ants. Formic acid is widely found in nature, such as in the secretions of red ants, bees, caterpillars, leaves and roots of plants, and fruits. It is the simplest carboxylic acid. Compared with other fatty carboxylic acids, it has a special structure and is more acidic. It ...Read more
