Silicone Mat Thermal Stability, Chemical Stability

- Jul 06, 2017 -

Laminated silicone rubber pad, also known as Silicone Mat, red silicone, silicone cloth, silicone film, silicone cloth, silicone rubber sheet, soft Silicone Mat, FPC flexible circuit board industry is often used for traditional press; is a highly active adsorption material , Is an amorphous material, the chemical formula for the mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, in addition to alkali, hydrofluoric acid does not react with any substance. Various types of silica gel because of its different manufacturing methods to form a different microporous structure. The chemical composition and physical structure of silica gel, it has many other similar materials difficult to replace the characteristics of: adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc.

Silica gel pad commonly used colors are red silicone rubber pad, gray silicone cloth, white silicone film, black silicone cloth, blue silicone rubber, SG green silicone film; widely used in PCB circuit board traditional press, fast press processing FPC flexible circuit Board, CCL copper clad laminate, soft and hard combination circuit board, multilayer circuit board, precision circuit board, FR4 epoxy board.

1, the proposed use of the temperature at 160 ~ 190 ° C operations, if a long time at 200 ° C or more operations, the glass fiber is easy to aging and reduce the service life;

2, if the press pressure is higher than 100kg / cm2 will reduce the service life;

3, if the press time in 60 minutes / time or more, the service life will be reduced;

4, the proposed monthly test equipment hot plate flatness, the upper and lower hot plate press fit in the 0.01mm below.

The use of raw materials are selected non-toxic environmentally friendly synthetic rubber and natural rubber. Synthetic rubber neoprene, butadiene rubber,Silicone Mat styrene butadiene rubber and so on. The structure of natural rubber is high polymer, rubber deformation by the external zigzag deformation, can quickly restore, have good chemical stability and mechanical properties. It has a very good softness, can be used in some high and low temperature conditions, and rubber products for low temperature applications less than the use of silicone products, in many ways now we have chosen to replace the rubber products with silicone products seat.

High compressibility, soft and elastic, suitable for use in low pressure applications

Ultra-high thermal conductivity; electrical insulation

Meet ROHS and UL environmental requirements

Natural sticky § thermal silica gel pad for aluminum plate between the shell

Description: The role of thermal silica film is the work of the aluminum plate heat to the bottom of the LED lights on the shell.

Thermal silicone film in high-power LED, backlight and other industries mainly focus on the following aspects:

1, a large area need to heat, large area, the use of thermal conductivity thermal grease (or thermal paste) smear inconvenient.

2, the length of the area of the heat. Such as: length 400 * width 4mm such a size using thermal grease (or thermal paste) easy to apply to the product outside.

3, high and low, the use can not be filled with heat, it should also use thermal silica film to heat.

4, small size need to heat, it should also use thermal silica gel film to heat.

5, requires easy operation or need to save labor costs, thermal Silicone Mat is the preferred material.
