Pigments are colorants used to impart specific hues to PVC products. They include inorganic and organic types (such as phthalocyanines). Pigments must be compatible with PVC's chemistry to ensure color stability and resistance to fading or degradation. They are typically dispersed in PVC formulations using masterbatches for consistent coloration across batches.
OB-1: A fluorescent whitening agent used to enhance the brightness of PVC products by absorbing UV light and re-emitting it as visible blue light, making the material appear whiter.
OB (Optical Brighteners): Similar to OB-1, these are fluorescent dyes that improve the brightness and appearance of PVC products under UV light, commonly used in applications where visual appeal is critical.
Carbon Black: A pigment used in PVC formulations to impart black color and enhance UV resistance and weatherability, commonly found in applications requiring high durability and protection from sunlight.
Titanium Dioxide: An inorganic pigment used primarily as a whitening agent in PVC formulations, providing excellent opacity, brightness, and UV resistance, crucial in applications requiring high color stability and protection against yellowing.
Colors: Organic and inorganic pigments used to impart various colors to PVC products, ranging from vibrant hues to subtle shades, depending on the desired aesthetic and functional requirements of the application.
