Introduction to the classification and production methods of tpu film
tpu film has the characteristics of good biocompatibility, non-toxicity, no allergic reaction, no local irritation, and no pyrogen. Widely used in health care and other related products, as well as sporting goods and protective products.
tpu film can be divided into two types: polyester and polyether
1. Polyester tpu film:
The zigzag shape is obvious after the polyester tpu film is torn.
Features of polyester tpu film: easy processing, heat resistance and oil resistance are better than polyether tpu film. Its application range is especially high-frequency molding, tpu film leather and sports equipment are more suitable.
2. Polyether tpu film:
The zigzag shape is not obvious after the polyether tpu film is torn.
Polyether tpu film characteristics: It has the advantages of excellent hydrolysis resistance, mildew resistance and antibacterial properties. Its hydrolysis resistance is better than polyester tpu film, which can prolong the hydrolysis time. Suitable for water sports equipment and medical equipment.
Several production methods of tpu film
1. Extrusion method: Add the Tpu raw material into the barrel of the extruder, heat and melt, extrude the sheet-shaped tpu film, cut the edge, and wind up.
2. Blow molding method: The molding feature of the blow molding method is to make the extruded tpu film into a tube blank through the annular gap mold, and at the same time, the compressed air is introduced from the mandrel axially, and the tpu film is clamped with a pair of clamping rods. Keep it at a constant internal pressure and expand to the desired diameter. After cooling and shaping, traction and coiling.
3. Calendering method: It is a method of continuously forming tpu film through several axles, which are heated inside and rotate adjacent to each other. The thickness of the tpu film depends on the clearance of the last axle.
4. Casting method: first melt, filter and defoam the TPU raw material, then send it into the casting machine, and cast the solution into a tpu film of a certain thickness through the casting nozzle.
