        English Name: l (+) - lactic acid

        English alias: (s) - (- +) - 2-hydropanoic acid; L(+)-Lactic acid solution; L-Lactic acid, free acid; lactate standard 40 mg/dl; L(+)lactic acid free acid sigmaultra; L-Lactic acid; (S)-2-Hydroxypropionic acid

        CAS:79-33-4

        EINECS:201-196-2

        Molecular formula: C3H6O3

        Boiling point: 125 ℃

        L-lactic acid is an organic acid refined from corn starch through biological fermentation. It is a colorless, clear and viscous liquid, and the aqueous solution is acidic. It can be freely mixed with water, ethanol or ether and is insoluble in chloroform. Because of its left-handed characteristics, it has good biocompatibility, can be compatible with mammals, can directly participate in human metabolism, without any side effects, and is widely used in food, medicine and other fields;

        Main uses: it can be used in fruit wine, beverage, meat, food, pastry production, pickle of vegetables (olives, cucumbers, pearl onions), canned processing, grain processing and fruit storage. It has the functions of adjusting pH value, bacteriostasis, extending shelf life, seasoning, maintaining food color and improving product quality.

      • Poly(lactic acid) (Low M.Wt.)

        Bending modulus: 100-150 MPa

        CAS NO.:26100-51-6

        Tensile strength: 40-60 MPa

        Elongation at break: 4-10%

        Elastic modulus: 3000-4000 MPa

         


        Polylactic acid (PLA) is a new type of biodegradable material, which is made from starch raw materials proposed by renewable plant resources (such as corn). Starch raw materials are made into lactic acid through fermentation, and then converted into polylactic acid through chemical synthesis.

         


        Application: extrusion grade resin, mainly used for fresh fruit packaging; Secondly, it is used in the packaging of electronic products that promote safety, energy saving and environmental protection. In addition, the application of extrusion grade resin in Horticulture has also begun to get attention. At present, it has been applied in slope greening, sand storm control and other fields.

      • Polyether ether ketone

        English Name: polyether ether ketone

        CAS:31694-16-3

        Molecular formula: c19h14f2o3

        Density: 1.26-1.32 g / cm3

        Melting point: 335-340 ° C

        Refractive index: 1.507, 1.732, 1.936

        Polyether ether ketone (PEEK) is a high polymer composed of a repeating unit containing one ketone bond and two ether bonds in the main chain structure, which is a special polymer material. It has physical and chemical properties such as high temperature resistance and chemical corrosion resistance. It is a semi crystalline polymer material, which can be used as high temperature resistant structural material and electrical insulation material, and can be compounded with glass fiber or carbon fiber to prepare reinforcement materials. Generally, a class of polyarylene ether polymers obtained by condensation with aromatic binary phenols are used. This kind of material has been widely used in aerospace field, medical equipment field (as artificial bone to repair bone defects) and industrial field.
