Laser Film Chemical Matting Agent Silica Dioxide

Why using silica dioxide into Medical Film?

In medical industries, especially in medical film industry to use silica dioxide, the main reason is because it has many functional

factors.

1. Biocompatibility: silica dioxide is a non-toxic material and it has excellent biocompatibiity which means it will not effect the bad

reactions of human’s body. This is so important to the medical instruments which are directly touched with human’s body.

2. Transparency: the medical film which is produced by silica dioxide can keep a high level of transparency. This is critical for medical

applications that require viewing the interior of a thin film, such as observing cells or tissues under an optical microscope.

3. Chemical resistance: plastic film with silica dioxide has excellent chemical resistance which can resist so much erosions due to

common disinfectants and drugs to extend medical instruments’ using life.

4. Surface properties: Through specific treatment methods, silica films can have specific surface properties, such as hydrophilicity or

hydrophobicity, which helps control the behavior of liquids on their surfaces and is particularly useful for certain medical applications

(such as drug delivery systems).

5. Strength and hardness: Silica itself is a hard material, and the film made of it also has high strength and hardness, which can withstand

the physical pressure during medical operations.

6. Biodegradability: Although unmodified pure silica may not be biodegradable, by introducing specific modification techniques, biodegradable

silica-based composite materials can be prepared, which provides the possibility for absorbable medical devices.

In summary, silica has a wide range of advantages in the application of medical films due to its unique physical, chemical and biological

properties, making it one of the indispensable materials in the medical field.
