Advantages Of Liquid Silicone In Water-proof In 3C Electronic Products

Jul. 28, 2023

Liquid silicone is a material that is waterproof, has good fluidity, fast vulcanization speed, is safer and more environmentally friendly, and can fully meet the requirements of edible and medical grade products, which has been widely promoted and popularized in all aspects of the manufacturing field.

Advantages Of Liquid Silicone In Water-proof In 3C Electronic Products


What Is Liquid Silicone?

Liquid silicone is a general term for liquid silicone rubber, which is different from solid silicone rubber, the most notable feature is its liquid form relative to solid silicone rubber.


What Are The Advantages Of Liquid Silicone For Water-proof In 3C Electronic Products?

1. Performance Advantages

Liquid silicone is known for its good thermal stability, cold resistance, electrical insulation properties and no toxic substances produced when burned.

2. Process Advantages

1) The waterproof structure is simplified and the overall structure is more compact.

2) The assembly accuracy and repetition accuracy are improved, and the waterproof effect is improved.

3) Liquid silicone has reduced the assembly process of the silicone ring and reduce the cost.

4) The waterproof silicone ring has high bonding strength with the battery cover and the main case, and can be disassembled and assembled many times.

3. Molding Temperature Of Liquid Silicone

Liquid silicone is a thermosetting material that needs to be cured at a certain temperature. The higher the temperature, the faster the curing speed of the silicone, but the heat resistance of the plastic material must be considered.

4. Good Elasticity, Aging Resistance

Liquid silicone has very good elasticity, even if it is used for a long time, it will not cause its elasticity to deteriorate, thereby reducing the waterproof function. Good aging resistance also greatly ensures the waterproof performance of silicone, so that the waterproof performance of liquid silicone can be maintained for a long time.

5. Stability

Liquid silicone has good stability, it can withstand high temperature and low temperature, which makes it easier to process, and there will be no harsh requirements on processing conditions.

6. Non-toxic And Harmless

Liquid silicone is transparent, tasteless, non-toxic and harmless to the human body, all products can pass ROHS, UL, FDA, LFGB certification, and the products can be sold to countries such as Europe, America and Asia.

7. Strong Waterproof Performance

Electronic products have very high requirements for waterproofing. The raw materials themselves have poor resilience and poor waterproofing effect, which affects consumers' purchase rate and consumers' perception of brands. Liquid silicone has a very strong waterproof performance, and it can be used in electronic products to achieve the highest quality and comprehensive waterproof.

8. Good Aging Resistance:

Liquid silicone can become a very popular waterproof material for electronics manufacturers because of its very good aging resistance. Liquid silicone will not reduce or change the waterproof performance due to changes in time.


The Principle Of Liquid Silicone Waterproof In 3C Electronic Products?

In terms of application, the silicone overmolding process is generally used, and the liquid silicone is overmolded on the surface of plastic parts or hardware parts to obtain new accessories that combine soft and hard. Other accessories squeeze the soft rubber part of the liquid silicone, thereby It has the effect of sealing and waterproofing.
