Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer of high-quality chemicals for various industries. One of their most notable products is HO-(C4H8O)n-C3H6O-(C4H8O)n-H, also known as UNIOL PB-500, UNIOL PB-700, UNIOL PB-1000, UNIOL PB-2000, UNIOL PB-4800, 1,2-Propanediol and 1,2-Butylene oxide polymers, Polymers of 1,2-Propanediol and Ethyl Oxide, 1,2-Propanediol, polymer with ethyloxirane, or PBG.

This product is a polybutyleneglycol that is widely used in various applications due to its excellent properties. It is a colorless and odorless liquid that is miscible with water, alcohols, and many organic solvents. It has a low viscosity, high boiling point, and low toxicity, making it safe and easy to handle.

One of the most significant advantages of UNIOL PBG is its versatility. It can be used as a lubricant, plasticizer, surfactant, humectant, and solvent in various industrial processes. It can also be used in the production of polyurethane foams, resins, and coatings, as well as in the manufacture of personal care products, such as lotions, shampoos, and cosmetics.

UNIOL PBG is available in various grades, ranging from UNIOL PB-500 to UNIOL PB-4800, depending on the molecular weight. This allows manufacturers to choose the grade that best suits their specific application requirements.

UNIOL PB-500 is a low-molecular-weight polybutyleneglycol with a molecular weight of approximately 500. It is mainly used as a solvent and surface-active agent in the production of personal care products and cosmetics.

UNIOL PB-700 is a medium-molecular-weight polybutyleneglycol with a molecular weight of approximately 700. It is mainly used as a lubricant and plasticizer in the production of polyurethane foams and resins.

UNIOL PB-1000 is a medium-molecular-weight polybutyleneglycol with a molecular weight of approximately 1000. It is mainly used as a humectant and plasticizer in the production of personal care products, such as lotions and shampoos.

UNIOL PB-2000 is a high-molecular-weight polybutyleneglycol with a molecular weight of approximately 2000. It is mainly used as a solvent and surface-active agent in the production of personal care products and cosmetics.

UNIOL PB-4800 is a very high-molecular-weight polybutyleneglycol with a molecular weight of approximately 4800. It is mainly used as a lubricant and plasticizer in the production of polyurethane foams and resins.

Another advantage of UNIOL PBG is that it can be easily synthesized from 1,2-Propanediol and 1,2-Butylene oxide. This process produces a high-quality product that is free from impurities and contaminants, ensuring its safety and reliability.

In addition, UNIOL PBG can be modified by copolymerization with other monomers, such as ethylene oxide or propylene oxide, to produce polymers with different properties and applications. For example, the polymer of 1,2-Propanediol and Ethyl Oxide is a water-soluble copolymer that is used as a thickener and stabilizer in the production of personal care products and cosmetics. The polymer of 1,2-Propanediol and Ethyloxirane is a thermoplastic polymer that is used in the production of films, fibers, and molded parts.

In conclusion, UNIOL PBG is a safe and efficient chemical that is widely used in various industries. Its versatility, availability in various grades, and ease of synthesis and modification make it an ideal choice for manufacturers and suppliers. Whether in the production of personal care products, polyurethane foams, resins, or coatings, UNIOL PBG is a reliable and cost-effective solution for a wide range of applications.
