What causes powder to appear on the surface of PVC products? Powder appearing on the surface of PVC products, often referred to as "blooming" or "powdery bloom," is typically caused by the migration of certain additives or compounds to the surface of the material. Here are the primary causes: 1. Migration of Plasticizers: PVC products often contain plasticizers to enhance flexibility. Over time, especially under heat, humidity, or UV exposure, these plasticizers can migrate to the surface, formi

A fascinating look into the industrial manufacturing of a flexible hose. The process begins with PVC powder being fed into a specialized machine known as an extruder. Inside the machine, the powder is heated until it melts into a pliable state, where it is then forced through a die to create its signature tubular shape. As the hot tube emerges, it is immediately treated with a continuous stream of water. This rapid cooling is crucial as it sets the PVC, ensuring the hose maintains its structural
