The separator is a microporous and porous film, made of PP and PE as the main material, and is placed between the positive and negative electrodes inside the battery. Main function: Isolate the positive and negative plates, prevent the internal cathode and anode of the battery from short-circuiting, allow ions to pass through, and have the function of retaining the electrolyte. In fact, in addition to pp and PE isolation films, there is also a PET isolation film. So, what is the difference between PE isolation film and PET isolation film?

PE is a polymer organic compound with a simple structure, and is a widely used polymer material in the world today. PE isolation film uses special polyethylene plastic film as the base material, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density. The advantage of PE isolation film is that the protected product is not polluted, corroded, scratched during production, transportation, storage and use, and protects the original smooth and shiny surface, thereby improving product quality and market competitiveness.

PET isolation film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields.

Understanding the Differences Between PE Protective Film and PET

Protective films are commonly used to protect various surfaces from scratches, dust, and other types of damage during handling, transportation, and storage. Two of the most popular types of protective films are PE (polyethylene) and PET (polyethylene terephthalate) protective films. While both are effective in providing protection, they differ in their function and features. In this essay, we will discuss the different functions of PE protective film and PET protective film, and how they compare to each other.

PE protective film is a flexible, transparent film that is commonly used to protect surfaces such as glass, metal, and plastic. It is known for its durability and its ability to withstand various types of damage, such as scratches, abrasions, and impact. PE protective film is easy to apply and remove, and is ideal for protecting surfaces during transportation, handling, and storage.

PET protective film, on the other hand, is a rigid, clear film that is primarily used to protect electronic screens, such as mobile phones, tablets, and computers. PET protective film is highly transparent and provides excellent clarity and visibility. It is also scratch-resistant, making it ideal for protecting screens from everyday wear and tear.

One of the key differences between PE and PET protective films is their adhesive strength. PE protective film uses a low-tack adhesive, which means that it can be easily removed without leaving any residue on the surface. PET protective film, on the other hand, uses a high-tack adhesive, which provides a stronger hold and is ideal for protecting electronic screens from damage.

Another difference between the two types of protective films is their thickness. PE protective film is generally thicker than PET protective film, which makes it more durable and better able to withstand impact and abrasions. PET protective film, on the other hand, is thinner and more flexible, making it easier to apply and more suitable for protecting curved surfaces.

When it comes to pricing, PE protective film is generally more affordable than PET protective film. This is due to the difference in materials and manufacturing processes. PE protective film is made from polyethylene, which is a more cost-effective material than PET.

In conclusion, both PE protective film and PET protective film are effective solutions for protecting surfaces from scratches, dust, and other types of damage. While PE protective film is more commonly used for protecting surfaces such as glass, metal, and plastic, PET protective film is ideal for protecting electronic screens. Understanding the differences between the two types of protective films can help you choose the right solution for your specific needs.
