Synthetic Hydrotalcite is a layered double hydroxide(LDH), and layered compounds refer to a class of compounds with a layered structure, interlayer ions, and exchangeability. Due to its unique layered structure and excellent physical and chemical properties, it has efficient acid absorption performance and good thermal stability.
Unique layered structure
Syntheic Hydrotalcite, due to its unique layered structure, contains exchangeable anions between the layers.The layered structure is adjustable, and by adjusting the synthesis conditions, its interlayer spacing and chemical composition can be adjusted to customize its performance to meet different needs.
High acid absorption performance and stable acid absorption effect
Syntheic Hydrotalcite can maintain good acid absorption performance even at high temperatures, which helps to delay the degradation process of materials.And due to its large specific surface area and porous structure, hydrotalcite exhibits significant adsorption properties. It can efficiently adsorb organic pollutants, heavy metal ions, and other harmful substances.
Excellent thermal stability
Syntheic Hydrotalcite exhibits excellent thermal stability under high temperature conditions and is not easily decomposed or deteriorated. Adding hydrotalcite to the polymer can significantly improve the thermal stability of the material, maintain structural stability, and extend its service life.
Environmental friendliness
Syntheic Hydrotalcite is composed of magnesium and aluminum hydroxides, which are naturally non-toxic and harmless to the environment and human health.As an inorganic material, hydrotalcite is a green and environmentally friendly functional material,it can replace traditional toxic stabilizers and reduce the harm to the environment and health.
MBS(Methylmetharylate-Butadiene-Styrene),commonly known as MBS impact modifier or MBS resin, is a new type of polymer material synthesized under the particle design concept. It is prepared by lotion grafting polymerization of methyl methacrylate (M), butadiene (B) and styrene (S).It has typical core-shell structure in submicroscopic morphology. The core is a spherical rubber core with a diameter of 10 nm ~ 100 mm, and the outside is a shell composed of styrene and methyl methacrylate. Because the dissolution parameters of methyl methacrylate and polyvinyl chloride (PVC) are similar,It acts as an interface adhesive between PVC resin and rubber particles, forms homogeneous phase in the process of processing and mixing with PVC, and gives the product excellent impact resistance.
MBS impact modifier is similar to other types of modifiers. It is a PVC / MBS Blend composite system formed by blending with PVC. It has excellent weather resistance, impact resistance, aging resistance, coloring, toughness and processing fluidity. It is widely used in PVC hard sheet, pipe, plate, interior decoration board, film, bottle material and various profile products.
CPE135A is a model of chlorinated polyethylene. The first digit 1 represents that the residual crystallinity (TAC) is 0-10%, the second and third digits 35 represent that the chlorine content is 35%, and the last digit a represents the molecular weight of PE. As a PVC impact modifier, CPE135A has many advantages, such as low price, excellent performance and excellent aging resistance. However, there are some disadvantages in the use of CPE135A for products with high impact resistance, high hardness and low temperature resistance. Chlorinated polyethylene CPE135A is used for plastic modification. It is prepared by chlorination of special polyethylene under the action of chlorine atoms. It has excellent comprehensive physical properties, such as high toughness at low temperature; High tensile strength; It is quite close to the solubility parameters of PVC and has good affinity; Given the correct processing conditions, a network structure is formed inside the hard PVC products, so as to give the products excellent normal and low temperature toughness and impact strength.
Oxidized polyethylene waxis made from polyethylene wax after special oxidation process. The molecular chain has certain functional groups, so its miscibility with polar resin has been significantly improved. Due to a certain amount of carbonyl and hydroxyl groups in the molecular chain of oxidized polyethylene wax, the compatibility with fillers, pigments and polar resins is significantly improved. The wettability and dispersibility in polar system are better than that of polyethylene wax, and it also has coupling property. Due to its high melting point and low viscosity, it promotes good resin fluidity, relatively reduces the power consumption of resin mixing, reduces the adhesion between resin and mold, is easy to remove film, plays the role of internal and external lubrication, and has good antistatic property.
In the plastic processing industry, the internal and external lubrication of PVC is relatively balanced. The lubricity of oxidized polyethylene wax added to the rigid, transparent and opaque PVC formula is better than that of other lubricants. It can also be used as raw and auxiliary materials for textile softener, car wax and leather softener. It can be used as dispersant, lubricant, brightener and coupling agent of pigment or filler such as dense masterbatch, polypropylene masterbatch, additive masterbatch and filling masterbatch. Rubber and plastic processing lubricants, film removers and phase solvents. In the formulation of waterborne coatings and inks, it provides excellent wear resistance, adhesion resistance and scratch resistance
