What is the difference between poor quality insulation film and good insulation film? There are five differences in normal situations.

1. Poor light transmittance: If you are using low-quality insulation film, it is made of ordinary and inexpensive pigments and due to the process, it is prone to refraction and random reflection of light, which can easily cause eye diseases in personnel.

2. Harmful substances: Poor quality materials and adhesives contain a large amount of high-risk substances such as formaldehyde and benzene, which are easily decomposed and volatilized under the effects of light and heat, posing a health hazard to users.

3. Poor UV isolation: Poor quality film manufacturers can only add a small amount of UV blocking agent to the installation adhesive due to production capacity limitations, rather than inside the film. The effect of isolating ultraviolet rays is very poor, but good films can basically avoid this.

4. Low insulation rate: Poor quality films are mostly tea paper and dyed films, which easily fade and have no obvious insulation effect, so the price is naturally much lower.

5. Scratch resistant layer: Poor quality films with added dyes are relatively thick, making it easy for the outer layer to be scratched.

Through the above points, you will find that if you buy inferior insulation film, not only will it cost you money, but it will also affect our health. If it is not used for a year, it may not be worth it. Then you need to pay for it, and if it looks bad, you will have to remove it, which is also very annoying. It also costs money to find someone, which can be said to be a loss that outweighs the gain.
