A. Silicone cloth:

Silicone cloth is made of glass fiber base cloth coated with silicone rubber.

From the coated surface, there are two types of silicone cloth: single-sided silicone cloth, double-sided silicone cloth, single-sided and double-sided silicone cloth are basically similar in application characteristics, single-sided silicone cloth is mainly used in some special environments that do not require double-sided silicone In order to save related costs, for example, when making shoes, only one side is required to resist chemical corrosion (such as a sauna).

According to the type of silica gel, there are two types of silicone cloth: room temperature curing silicone cloth and high temperature curing silicone cloth. Dongguan Silicone

Difference: different temperature resistance range, different curing strength, different performance after burning (smoke and tasteless at high temperature curing. Quick extinguishment, white ashes), and different service life.

B. Application range of silicone cloth:

1. Electrical insulation: Silicone cloth has a high electrical insulation level, can withstand high voltage loads, and can be made into insulating cloth, bushings and other products.

2. Non-metal compensator: Silicone cloth can be used as a flexible connection device for pipelines. It can solve the damage caused by thermal expansion and contraction. Silicone cloth has high temperature resistance, corrosion resistance, anti-aging performance, good elasticity and flexibility , Can be widely used in petroleum, chemical, cement, energy and other fields.

3. Anti-corrosion: Silicone rubber coated glass fiber cloth can be used as a pipeline, the internal and external anti-corrosion layer of the deposit. It has excellent anti-corrosion performance and high strength.

4. Temperature resistance: as a fire blanket, fire curtain, temperature resistant flame retardant material.

5. Other fields: Silicone rubber coated glass fiber membrane structural materials can be used in construction sealing materials, high temperature anticorrosive conveyor belts, packaging materials and other fields.

6. As a temperature-resistant, anti-corrosion conveyor belt, such as shoe materials.

C. Specification of silicone cloth:

Style number Thickness (mm) Breaking strength (n / 50mm) Bursting strength Mpa Width (mm)

5013 0.13 1500/1200 2.0 0--1250

5025 0.25 1800/1500 2.1 0-1500

5040 0.40 2000/1600 2.2 0-1500

5050 0.50 2200/1800 2.3 0-1500

5060 0.60 2400/2200 2.4 0-1500

5070 0.70 2500/2300 2.4 0-1500

5080 0.80 2600/2400 2.5 0-1500

5090 0.90 2800/2600 2.5 0-1500

5100 1.00 3000/2800 2.6 0-1500

5120 1.20 3400/3000 2.5 0-1500

5150 1.50 3700/3300 2.3 0-1500

5200 2.00 4200/3800 2.2 0-1500

Silicone cloth with a size of more than 2 mm can also be produced in large quantities.

Single-sided silicone cloth of the same specification can be produced.

D. Application characteristics of silicone cloth:

1. Used between low temperature -70 ℃ and high temperature 230 ℃. Dongguan Silicone

2. Resistance to ozone, oxygen, light and weather aging, excellent weather resistance in field use, life span up to 10 years.

3. With high insulation performance, dielectric constant 3-3.2, breakdown voltage 20-50KV / MM.

4. Good flexibility, large surface friction and good elasticity.

5. Chemical resistance.
