MT-PET is an ultra-thin heat shrinkable tubing made of polyethylene terephthalate (PET) with excellent heat resistance and dielectric strength, suitable for various medical instruments and equipment, such as endoscopes, minimally invasive surgical instruments, medical equipment components, etc. The thin wall thickness provides good insulation protection for various applications without increasing the total diameter of the instruments too much and prevents them from being damaged by high-temperature environments. Highly transparent visual properties clearly show the status and position of the internal components of medical instruments, which is convenient for observation and inspection. It has stable protection and resistance to chemical substances, which can provide all-round protection for medical instruments.
