Silicone production specifications Silicone rubber features Silicon advantages and disadvantages

Characteristic characteristics

The main component of silica gel is silicon dioxide, which is chemically stable and non-toxic. Silica gel is a highly active adsorption material and is an amorphous substance. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.
Features

Silicone rubber is a new type of polymer elastic material with excellent high temperature resistance (250-300 ° C) and low temperature resistance (-40-60 ° C). It has good physiological stability and can withstand repeated and severe requirements. And disinfection conditions, with excellent resilience and permanent deformation (200 ° C 48 hours no more than 50%), breakdown voltage (20-25KV / mm), ozone resistance, UV resistance. It is resistant to radiation and has special oil resistance.

Performance characteristics

Features:

1 continuous use temperature range: -60 ° C ~ 200 ° C.

2 soft, arc resistant, corona resistant.

3 can be customized according to customer requirements.

4 harmless, non-toxic and tasteless.

5 high pressure and environmental protection.

Standard colors: black, red, blue, white, gray, green, transparent (other colors can be produced as required).

Remarks: The above data is the result of one-time vulcanization test.

The vulcanizing agent C-8 was added in an amount of 2%, and the vulcanization condition was 170 ° C × 5 min × 15 Mpa.

The results in the table are typical data for this model, and each batch will have a certain deviation.

The difference with PVC 

Among the rubber and plastic materials, silicone rubber materials belong to a class of products that are environmentally friendly and safe. In addition to silicone materials, there are also many materials similar to silicone for consumers to choose. PVC is one of them. In real life, both silicone and PVC materials belong to Commonly used rubber. 

How to distinguish it? From the appearance we can see the texture, color, temperature, hardness, rebound. In terms of technology, they have different processes, different production processes and different machines. Of course, some machine technologies can produce silicone or PVC products at the same time.

Field of use

1. Silicone products are an indispensable part of making copiers, keyboards, electronic dictionaries, remote controls, toys, silicone buttons, etc.

2. It can be used to make durable forming gaskets, packaging materials for electronic parts, and maintenance materials for automotive electronic parts.

3. It can be used for making electronic components and molding high-point pressure edges.

4. It can be used to make conductive silica gel, medical silica gel, foam silica gel, molding silica gel, etc.

5. It is used for the construction and repair of houses, the sealing of high-speed kilometers, the sealing of bridges and other sealing projects.

6. Can be used for baby products, mother and baby products, baby bottles, bottle protectors.

7. It can be used in the production of kitchen products, kitchenware and related auxiliary kitchenware products

8. It can be used for medical device accessories. Because of its colorless, odorless, and non-toxic properties, silica gel is widely used in the medical industry.
