During the processing, storage, and application of PVC heat shrinkable film, under the action of light, heat, and oxygen, aging phenomena such as fading, embrittlement, and cracking will occur. PVC heat shrinkable film is necessary to participate in stabilizers to delay and prevent aging. The first to prevent thermal aging is called a heat stabilizer; the first to prevent oxidative aging is called an antioxidant; the first to prevent photoaging is called a light stabilizer, and they are collectively called stabilizers.
Today’s excellent PVC heat shrinkable film stabilizer is methyl tin heat stabilizer (referred to as 181), which is very good for calendering, extrusion, injection and blow molding of rigid polyethylene (PVC). Because of its high performance, it is especially used for food packaging and high-definition rigid polyethylene products. Together, it is also widely used in plastic doors and windows, water pipes, and decorative materials to replace other highly toxic plastics. Heat stabilizers.
PVC heat shrinkable film is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.
