For chemical buyers navigating the complex global market, identifying reliable sources for specialized compounds is critical. One such compound gaining attention for its versatility is 1,2-Propanediol, Polymer With Ethyloxirane, identified by its CAS number 31923-86-1. This article serves as a guide for buyers, outlining the key considerations when sourcing this material, from understanding its properties and applications to selecting the right manufacturer and supplier.

1,2-Propanediol, Polymer With Ethyloxirane (PBG) is a synthetic polyether that offers a unique combination of thermal stability, low volatility, and controllable viscosity. Its chemical structure, HO-(C4H8O)n-C3H6O-(C4H8O)n-H, allows it to function effectively in diverse industrial applications. For chemical buyers, understanding these characteristics is the first step in determining if PBG is the right fit for their needs. Common applications include its use as a plasticizer in the plastics industry, a base for lubricants, and an additive in adhesives and sealants.

When looking to purchase CAS 31923-86-1, it is essential to consider the specific grade and specifications required. Factors such as molecular weight, hydroxyl value (e.g., 113.87 mgKOH/g), and acid value (e.g., 0.06 mgKOH/g) can vary between manufacturers and impact performance. A reputable supplier will readily provide detailed technical data sheets for their products, enabling buyers to make informed decisions. For instance, knowing the exact viscosity (e.g., 90 mm²/s at 40°C) is crucial for lubricant applications.

The global supply landscape for chemicals like PBG is robust, with many manufacturers and suppliers operating worldwide. However, China has emerged as a significant hub for fine chemical production. Companies like Ningbo Inno Pharmchem Co., Ltd. are well-established players in this market, offering a wide range of chemical intermediates and polymers. For buyers, sourcing from such Chinese manufacturers can often translate into competitive pricing and the ability to secure bulk quantities. When evaluating suppliers, look for those with a strong track record, robust quality control systems, and a commitment to customer service.

Key questions for chemical buyers to ask potential suppliers include their production capacity, lead times for delivery, minimum order quantities, and any certifications they hold (e.g., ISO). Understanding the supplier's ability to provide consistent quality batch after batch is paramount, especially for applications where product integrity is critical. Additionally, inquire about their flexibility for custom synthesis or modification if standard grades do not precisely meet your requirements. The goal is to establish a reliable, long-term supply partnership.

In conclusion, sourcing 1,2-Propanediol, Polymer With Ethyloxirane (CAS 31923-86-1) requires a thorough understanding of the product's capabilities and a strategic approach to supplier selection. By focusing on product specifications, application suitability, and the reliability of manufacturers and suppliers, chemical buyers can ensure they procure this versatile polymer effectively, securing quality materials at competitive prices for their manufacturing processes.
