• YIHOO PA(polyamide) polymerization & modification additives

    YIHOO PA(polyamide) polymerization & modification additives

    Polyamide (also called PA or Nylon) is the generic terms of thermoplastic resin, containing repeated amide group on the main molecular chain. PA includes aliphatic PA, aliphatic – aromatic PA and aromatic PA, in which aliphatic PA, derived from the number of carbon atoms in the synthetic monomer, has the most varieties, the most capability and the extensive application.

    With the miniaturization of automobiles, the high performance of electronic and electrical equipment, and the acceleration of the lightweight process of mechanical equipment, the demand for nylon will be higher and greater. Nylon inherent shortcomings are also an important factor limiting its application, especially for PA6 and PA66, compared with PA46, PA12 varieties, have a strong price advantage, although some performance can not meet the requirements of the development of related industries.

  • YIHOO PU(polyurethane) foaming additives

    YIHOO PU(polyurethane) foaming additives

    Foam plastic is one of the main varieties of polyurethane synthetic materials, with the characteristic of porosity, so its relative density is small, and its specific strength is high. According to the different raw materials and formula, it can be made into soft, semi-rigid and rigid polyurethane foam plastic etc..

    PU foam is widely used, almost infiltrating into all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, insulation and many other applications.

  • YIHOO PVC(polyvinyl chloride) polymerization &modification additives

    YIHOO PVC(polyvinyl chloride) polymerization &modification additives

    Polyvinyl chloride (PVC) is a polymer of vinyl chloride monomer (VCM) polymerized by peroxide, azo compounds and other initiators or by free radical polymerization reaction mechanism under the action of light and heat.  Vinyl chloride homo polymer and vinyl chloride co polymer are called vinyl chloride resin.

    PVC used to be the largest general-purpose plastic in the world and was widely used.  It is widely used in building materials, industrial products, daily necessities, floor leather, floor bricks, artificial leather, pipes, wires and cables, packaging film, bottles, foaming materials, sealing materials, fibers and so on.

  • YIHOO PC(Polycarbonate) additives

    YIHOO PC(Polycarbonate) additives

    Polycarbonate (PC) is a polymer containing carbonate group in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic – aromatic and other types. The low mechanical properties of aliphatic and aliphatic aromatic polycarbonate limit their application in engineering plastics. Only aromatic polycarbonate has been industrially produced.  Due to the particularity of polycarbonate structure, PC has become the general engineering plastics with the fastest growth rate among the five engineering plastics.

    PC is not resistant to ultraviolet light, strong alkali, and scratch. It turns yellow with long-term exposure to ultraviolet.  Therefore, the need for modified additives is essential.

  • YIHOO TPU elastomer(Thermoplastic polyurethane elastomer) additives

    YIHOO TPU elastomer(Thermoplastic polyurethane elastomer) additives

    Thermoplastic polyurethane elastomer (TPU), with its excellent properties and wide application, has become one of the important thermoplastic elastomer materials, whose molecules are basically linear with little or no chemical crosslinking.

    There are many physical crosslinks formed by hydrogen bonds between linear polyurethane molecular chains, which play a strengthening role in their morphology, thus giving many excellent properties, such as high modulus, high strength, excellent wear resistance, chemical resistance, hydrolysis resistance, high and low temperature resistance and mold resistance.  These excellent properties make thermoplastic polyurethane widely used in many fields such as footwear, cable, clothing, automobile, medicine and health, pipe, film and sheet.

  • YIHOO Low VOC automotive trim additives

    YIHOO Low VOC automotive trim additives

    In recent years, with the implementation of in-car air quality regulations, in-car control quality and VOC(volatile Organic Compounds) level have become an important part of automobile quality inspection.  VOC is the command of organic compounds, mainly refers to the vehicle cabin and baggage cabin parts or materials of organic compounds, mainly including benzene series, aldehydes and ketones and undecane, butyl acetate, phthalates and so on.

    When the concentration of VOC in the vehicle reaches a certain level, it will cause symptoms such as headache, nausea, vomiting and fatigue, and even cause convulsions and coma in serious cases. It will damage the liver, kidney, brain and nervous system, resulting in memory loss and other serious consequences, which is a threat to human health.

  • YIHOO textile finishing agent additives

    YIHOO textile finishing agent additives

    Textile finishing agent is a chemical reagent for textile finishing.  Due to there are several varieties, it’s suggested to choose the right type according to the requirements and the grades of chemical finishing.  During processing, the low molecular finishing agent is mostly solution, while the high molecular finishing agent is mostly emulsion.  Together with finishing agent, UV absorber, colour fastness enhancement agent and other auxiliaries are also requested during production.

  • YIHOO General plastics additives

    YIHOO General plastics additives

    Polymers have become a necessity in virtually every aspect of modern life, and recent advances in their production and processing have further broadened the use of plastics, and in some applications, polymers have even replaced other materials such as glass, metal, paper and wood.

  • YIHOO General coating additives

    YIHOO General coating additives

    Under special circumstances, coatings and paints such as outdoor paint, paint, car paint, would accelerate aging procedure, after long-term exposure to ultraviolet radiation, light aging, thermal oxygen.

    The most effective way to improve the coating’s weather resistance level is to add antioxidant and light stabilizer, which can effectively inhibit the free radicals oxidation in plastic resin, decomposition of hydrogen peroxide, and capture free radicals, in order to provide long-lasting protection for plastic resin, and greatly delay the loss of gloss, yellowing and pulverization of coating.

  • Cosmetics additives

    Cosmetics additives

    In recent years, with the acceleration of industrialization, human’s influence on the natural environment is increasing, which makes the protective effect of ozone layer tends to decrease. The intensity of ultraviolet rays reaching the earth’s surface in sunlight is increasing, which directly threatens human health. In daily life, in order to reduce the damage of ultraviolet radiation to skin,  People should avoid exposure to sunlight and go out in the midday sun exposure time, wearing a protective clothing, and using sunscreen cosmetics in front of the sun protection, among them, the use of sunscreen cosmetics is the most commonly used uv protection measures, it can prevent the sunlight induced erythema and insolation injury, prevent or reduce DNA damage,  Regular use of sunscreen cosmetics can also inhibit pre-cancer skin damage, can significantly reduce the occurrence of solar cancer.
