Characteristics of tpu composite membrane

TPU composite film is a thermoplastic TPU elastomer. It is made of MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group after extrusion and mixing. Because of its good elasticity, good physical properties, and various mechanical strengths. very good. Therefore, it is generally used for production and processing such as injection, extrusion, calendering and dissolution into solution-based resin. Tpu composite film is a plastic material often used by plastic processors, and its products include industrial applications and civilian necessities.

  Characteristics of tpu composite membrane:

  1. Increase the thickness to save costs: TPU film is much more expensive than PET film, and the composite PET release film can increase the thickness and save costs.

  2. Improve tensile strength: TPU film has poor tensile strength and is easy to stretch. The tensile strength of PET release film is very good, and it is not easy to stretch. The combination of the two just makes up for the shortcomings of TPU.

  3. Improve the professional ability of anti-damage: the benefit of the composite tape is that the thickness is increased. At the same time, the anti-damage properties of the PET release film can also make up for the lack of the TPU film.

  4. Prevent anti-sticking: One side of the tpu composite film has an anti-sticking effect, so it is not easy to stick together when it is rolled up. It also has the properties of non-stick water.
