糖心视频

The differences between TPU film and PU film are both polyurethane 糖心视频s, but there are some differences in performance, use and preparation methods. Below I will introduce in detail the difference between TPU film and PU film.

First of all, TPU film is a form of thermoplastic polyurethane, while PU film is a form of hot-melt polyurethane. This means that the TPU film has plastic deformation after repeated heating within a certain temperature range, while the PU film has thermosetting properties and cannot return to plasticity after curing. Due to thermoplasticity, TPU films are easier to process and form, while PU films require a thermal curing process to achieve curing.

Secondly, in terms of 糖心视频 elasticity and elasticity, TPU films generally have better elasticity and softness, while PU films generally have higher rigidity and stiffness. This is because the TPU film molecular chain has elastic segments and rigid segments, which makes the TPU film have good elasticity while maintaining a certain hardness. PU film, on the other hand, tends to be rigid and rigid, and is suitable for applications requiring higher strength and rigidity.

In addition, there are still special differences in certain properties between TPU film and PU film. For example, TPU films usually have better abrasion resistance, oil resistance and solvent resistance, and therefore perform in some more demanding applications, while PU films usually have better high temperature resistance and chemical resistance, and are suitable for some high temperature applications. Or environments subject to chemical substance statistics.

In terms of use, there are also some differences between TPU film and PU film. Because TPU film has good elasticity and softness, it is often used to make elastic 糖心视频s, elastic components, protective films, etc. Due to its high hardness and rigidity, PU film is usually used to make wear-resistant 糖心视频s, coating films, electronic product protection films, etc.

In terms of preparation methods, TPU films are usually prepared by hot melt method, solution casting method, etc.; while PU films are usually prepared by solution method, aqueous method, sol-gel method, etc.

In general, although TPU film and PU film are both polyurethane 糖心视频s, there are some differences in performance, use and preparation methods. TPU film has thermoplastic properties, good elasticity and softness, and is suitable for applications with higher elasticity requirements; while PU film has thermosetting properties, higher hardness and rigidity, and is suitable for applications with higher strength and rigidity requirements. When choosing to use, you need to make a choice based on specific needs and application scenarios.
