Several production methods of TPU film
When TPU film manufacturers produce TPU film, the raw material is mainly TPU particles, which can be made into films after special processing such as calendering, casting, film blowing, and coating. Among many films, the application frequency of TPU film has been increasing in recent years. It is a kind of film with good wear resistance, heat preservation and environmental protection performance. Let's introduce several production methods of TPU film.
Extrusion method: add the tpu raw material into the barrel of the extruder, heat and melt, extrude the sheet-like TPU film, trim the edges, and wind it.
Blow molding: The molding feature of blow molding is that the extruded TPU film is made into a tube blank through an annular gap mold, and compressed air is introduced axially from the mandrel, and a pair of clamping rods are used to clamp the TPU film to make it. Maintaining constant internal pressure, expand to the desired diameter. After cooling and setting, traction coiling.
Calendering method: is a method of continuously forming a TPU film by several shafts, which are heated inside and rotated next to each other, the thickness of the TPU film depends on the gap of the last shaft.
Casting method: First, the TPU raw material is melted, filtered, and defoamed, and then sent to a casting machine, and the solution is cast into a TPU film of a certain thickness through a casting nozzle.
Stretching method: It is a film-forming method that stretches the TPU film longitudinally and transversely between the softening temperature and the melting temperature. 106. The stretching technology of the TPU film can be divided into uniaxial stretching and biaxial stretching, but in actual production Mainly use two-way stretching. Biaxial stretching can improve the properties of TPU films.
TPU film is becoming more and more popular because of its superior performance and environmental protection concept. The components of TPU film are polyester and polyether, which are classified differently in terms of color, air permeability, width and thickness, and are usually selected according to actual needs and process conditions. TPU film is also widely used in clothing fabric lamination, medical breathable tape and other fields. It is more in line with the requirements of environmental protection and energy saving advocated by the state.
