Whether silicone rubber is flame retardant, silicone flame retardant national standard

Silicone rubber is not flame retardant silicone, but the heat resistance of rubber is also outstanding, it can work for a long time at 180, slightly higher than 200 can withstand several weeks or more and still be elastic, and can withstand high temperatures of more than 300 in an instant.

Silicone rubber refers to rubber whose backbone is composed of alternating silicon and oxygen atoms, and two organic groups are usually attached to the silicon atoms. Ordinary silicone rubber is mainly composed of silicon-oxygen links containing methyl groups and a small amount of vinyl.

The introduction of phenyl group can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber. Silicone rubber has good low temperature resistance and can generally work at -55. After the introduction of phenyl group, it can reach -73.

How is flame retardant silicone flame retardant?

Legal analysis: The flame retardant grade is divided into three grades: FV0, FV1 and FV2, and the grades are reduced in turn. Flame retardant rubber sheet is a kind of rubber sheet that can inhibit the burning rate of the flame in the ignition state, or directly extinguish the flame.

According to its flame retardant performance, it can be divided into four standards: B3 grade, B2 grade, B1 grade and A grade, of which B3 grade rubber sheet is flammable, B2 grade is combustible, B1 grade is difficult to guess combustible combustion, and A grade is non-combustible.

Legal basis: Article 11 of the Standardization Law of the People's Republic of China can formulate recommended national standards to meet the technical requirements of basic general, supporting with mandatory national standards, and playing a leading role in relevant industries.

The recommended national standards shall be formulated by the administrative department of standardization.

It is flame retardant, (high-temperature resistant wires and flame retardant wires are made of silicone) but will still carbonize at extremely high temperatures.

Ordinary silicone rubber is not flame retardant at all, and can be lit with fire. It's just that silicone rubber is self-extinguishing, so it's easy to see black smoke. Only silicone rubber with flame retardant added will have certain flame retardant properties.

It is flame retardant adhesive, but the flame retardant grade of ordinary rubber is low, if you need a high level of flame retardant silicone, you should choose a flame retardant grade of silicone.

Flame retardant! C-Si itself is flame retardant!!

Legal analysis: The flame retardant grade is divided into three grades: FV0, Kuansochun FV1 and FV2, and the grades are reduced in turn. Flame retardant rubber sheet is a kind of rubber sheet that can suppress the burning rate of the flame or directly extinguish the flame in the ignition state.

According to its flame retardancy, it can be divided into four standards: B3 grade, B2 grade, B1 grade and A grade, of which B3 grade rubber sheet is easy to be cautious and flame resistant, B2 grade is flammable, B1 grade is flame retardant, and A grade is non-combustible.

Legal basis: Article 11 of the Standardization Law of the People's Republic of China can formulate recommended national standards to meet the technical requirements of basic general, supporting with mandatory national standards, and playing a leading role in relevant industries.

Recommended national standards are formulated by the competent administrative department of standardization.

Flame retardant silica gel is made of alumina hydrate, calcium carbonate, carbon black and platinum compounds as flame retardants, which can be configured into flame retardant silica gel. The average particle size of alumina hydrate should be less than 50um, the average particle size of calcium carbonate should be less than 20um, and the carbon black can be acetylene carbon black, hot cracking carbon black or furnace carbon black, and the specific surface area should be greater than 10 g, and the particle size; Platinum compounds can be platinum alcohol complexes, platinum vinyl siloxane complexes.

Features: One-component room-temperature curing silicone sealant, cured adhesive layer is elastomer; Neutral curing, non-corrosive to most of the source metals; It has the anti-cold and hot alternating performance, aging resistance and electrical insulation performance of Zhuo Hail Reputation Chunyue; The adhesive layer has excellent moisture-proof, shock-resistant, corona-resistant, and anti-leakage properties;

Typical uses: mechanical bonding and sealing of electronic and electrical components such as power supplies, photovoltaic modules, communication equipment, etc., as well as bonding and fixing of electronic components. Other metal, plastic, glass and other bonding seals with flame retardant requirements.
