There are significant differences between screen-printed silicone and ordinary silicone in many aspects. The following is a detailed analysis of the differences between the two:
1. Definition and basic characteristics
Screen-printed silicone: Screen-printed silicone is an indicator adsorbent with high added value and high technical content made from fine-porous silica gel with high active adsorption material as the basic raw material. It is made through deep processing. It is a high-grade adsorption desiccant. It not only has the basic characteristics of silica gel, but also has special patterns, texts, anti-slip and waterproof functions through screen printing technology.
Ordinary silicone: Ordinary silicone is a highly active adsorption material, an amorphous substance, with a chemical formula of mSiO2·nH2O, insoluble in water and any solvent, non-toxic and odorless, stable chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid.
2. Main uses
Screen-printed silicone:
Indicator adsorbent: Mainly used for moisture absorption and rust prevention of instruments, meters, equipment, etc. under closed conditions, and can visually indicate the relative humidity of the environment through color changes.
Silica gel desiccant for packaging: widely used in moisture-proof packaging for precision instruments, leather, shoes, clothing, food, medicines and household appliances.
Decorative and functional materials: Through screen printing technology, silk-screen silica gel can be firmly adhered to the surface of various materials, providing anti-slip, waterproof, high and low temperature resistance and other functions, and has a strong three-dimensional sense and beautiful decorative effect.
Ordinary silicone:
Industrial raw materials: widely used in the manufacture of silica gel products, such as silica gel tubes, silica gel strips, silica gel sheets, etc.
Desiccant: used as a common desiccant, absorbs moisture in the air and prevents items from getting damp.
Other uses: can also be used in medical, food, construction and other fields as sealing, heat insulation, shockproof and other materials.
3. Special properties
Screen-printed silicone:
Good adhesion: can be firmly adhered to the surface of various materials and is not easy to fall off.
High strength: has good tensile strength and tear strength.
Soft and delicate touch: comfortable to touch, no irritation.
Beautiful decorative effect: patterns and texts are clearly printed, with a strong three-dimensional sense and bright colors.
Excellent performance: non-toxic and harmless, environmentally friendly and safe, high temperature resistant, low temperature resistant, water resistant, breathable, etc.
Ordinary silicone:
Strong adsorption: has good adsorption capacity for moisture and some other substances.
Stable chemical properties: does not react with any substance except strong alkali and hydrofluoric acid.
Non-toxic and odorless: harmless to the human body and safe to use.
4. Processing technology
Screen-printed silicone: Printing patterns and texts on the surface of silicone through silk screen printing technology requires special printing equipment and ink.
Ordinary silicone: There are various processing methods, including molding processes such as molding, extrusion, and injection, without the need for special printing steps.
In summary, there are obvious differences between screen-printed silicone and ordinary silicone in terms of definition, use, special properties and processing technology. Silk screen silicone is endowed with more functions and decorative effects through silk screen printing technology, which is suitable for more diverse application scenarios.
