In the competitive landscape of plastic manufacturing, achieving a visually appealing finish is often the key differentiator for products. For manufacturers of polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC) products, enhancing brightness and whiteness is a common goal. This is where high-performance additives like Optical Brightener ER-I (CAS 13001-39-3) play a crucial role. As a leading manufacturer and supplier of specialty chemicals, we offer insights into why Optical Brightener ER-I is an excellent choice for your plastic formulations and how to efficiently buy it.

Optical Brightener ER-I is a sophisticated fluorescent whitening agent that works by absorbing ultraviolet light and re-emitting it as visible blue light. This phenomenon effectively neutralizes any yellowish tones present in plastic materials, resulting in a significantly brighter, cleaner, and more appealing appearance. For products ranging from packaging films and molded components to fibers and coatings, this enhancement can dramatically improve market appeal.

When procurement managers are sourcing chemicals, understanding the product's specifications and its performance characteristics is vital. Optical Brightener ER-I, characterized by its yellowish-green crystalline powder form, boasts a high purity level of ≥99% and a melting point range of 229-231°C. These properties ensure excellent compatibility and stability within various polymer matrices during processing, whether through extrusion, injection molding, or other shaping techniques. As a reliable supplier based in China, we ensure that every batch meets these stringent quality standards.

The integration of Optical Brightener ER-I into plastic formulations is typically done at low concentrations, often ranging from 0.02% to 0.08% by weight, depending on the specific polymer and the desired level of whiteness. Its effectiveness lies in its ability to provide a dramatic visual improvement without significantly altering the physical properties of the plastic. For companies looking to purchase this additive, understanding these application parameters is crucial for optimizing results and costs.

Moreover, Optical Brightener ER-I exhibits good fastness properties, which is essential for plastic products that may be exposed to light or heat. This means the enhanced whiteness and brightness are durable and long-lasting. For those in the market to buy, NINGBO INNO PHARMCHEM CO.,LTD. offers a dependable supply of this product. We cater to diverse industrial needs, providing both technical support and flexible purchasing options for bulk orders.
