For businesses in the polyurethane (PU) sector, securing a consistent supply of high-quality Toluene Diisocyanate (TDI) is paramount. As a leading manufacturer and supplier in China, understanding the nuances of TDI sourcing can significantly impact your production efficiency and cost-effectiveness. This guide aims to equip procurement managers and formulators with the knowledge to confidently purchase TDI, focusing on quality indicators and price negotiation.

Toluene Diisocyanate (TDI), identified by CAS No. 584-84-9, is a foundational aromatic diisocyanate crucial for producing flexible polyurethane foam, PU coatings, PU elastomers, synthetic leather, and adhesives. Its two primary isomers, 2,4-TDI and 2,6-TDI, are commercially supplied in various ratios, with the 80/20 blend being the most common for flexible foam applications. When you buy TDI, it's essential to specify the required isomer ratio to match your product formulation needs.

As a chemical intermediate, TDI's quality is often gauged by its purity percentage (typically 99.5% or higher), hydrolysis chlorine content, and acidity. Manufacturers committed to international standards, such as those certified by SGS, BV, or ISO9001, are more likely to provide consistent product quality. When evaluating a TDI supplier, look for transparency in their product parameters and quality control processes. For instance, understanding the trade-offs between different grades of TDI can help you optimize your formulation and reduce costs.

The price of Toluene Diisocyanate is influenced by global supply and demand, raw material costs, and production capacities. Manufacturers in China often offer competitive TDI prices due to scale advantages and localized production. When seeking to purchase TDI, engaging directly with manufacturers can unlock better pricing. A typical inquiry might involve requesting a quote for specific quantities, such as 20-99 tons or 100+ tons, to leverage volume discounts. For example, comparing prices between a 20-ton order and a 100-ton order from a single supplier can reveal significant savings.

Beyond price, consider the supplier's reliability, including their years of export experience and self-branded product lines. A reputable manufacturer will have robust logistics and packaging solutions, such as 250kg iron drums, ensuring safe transport and timely delivery, typically within 15 days. Working with a seasoned TDI supplier not only guarantees product quality but also streamlines your procurement process, allowing you to focus on innovation and production.

For those looking to source Toluene Diisocyanate, engaging with established manufacturers in China offers a strategic advantage. By focusing on product specifications, supplier reliability, and competitive pricing, you can ensure a steady supply of this vital chemical intermediate. If you are looking to buy TDI or need a quote for your polyurethane manufacturing needs, consider reaching out to experienced suppliers who can provide both high-quality products and expert support.
