At Ningbo Inno Pharmchem Co., Ltd., we are committed to being a leading source for high-quality chemical intermediates. Among our extensive product portfolio, the 1,2-Propanediol Polymer with Ethyloxirane, often referred to as PBG, stands out for its distinctive chemical and physical properties. As a trusted 1,2-Propanediol polymer with ethyloxirane supplier, understanding these properties is crucial for our clients to maximize its utility.

The molecular structure of PBG, represented by the formula HO-(C4H8O)n-C3H6O-(C4H8O)n-H, is a key determinant of its performance. Its exact mass of 148.11000 and a calculated LogP of 0.15470 indicate a degree of hydrophilicity, contributing to its excellent solubility in various solvents. This makes it an adaptable component in numerous formulations, a benefit that our clients actively seek when they look to buy PBG for their manufacturing processes.

Key specifications for PBG, such as its low water content (0.02%) and minimal double bond presence (0.004 mmol/L), underscore its purity and stability. The acid value is remarkably low at 0.06 mgKOH/g, and the hydroxyl value of 113.87 mgKOH/g signifies its reactivity and utility as a building block in polymer chemistry. As a leading manufacturer in China, we ensure these specifications are consistently met across all our product batches.

The viscosity of PBG, measured at 90 mm²/s at 40℃, is another critical parameter. This viscosity, combined with its role as a Polybutyleneglycol supplier, positions it as an ideal material for applications requiring specific flow characteristics. Furthermore, its higher molecular weight (MW: 985) contributes to its effectiveness in enhancing the properties of end-products, particularly in the realm of plastic additives.

For businesses seeking a reliable source for this versatile chemical, exploring the CAS 31923-86-1 applications further reveals its broad utility. It serves as a fundamental component in the production of adhesives, coatings, resins, and even personal care products. Our expertise as a high molecular weight polymer manufacturer allows us to support these diverse industrial needs with confidence and precision. We are proud to be a partner in your innovation journey.
