Chengde polycarbonate sheet How is the quality? Chengde polycarbonate sheet is made of Bayer materials imported from Germany, with flame retardant properties, the natural temperature of the polycarbonate sheet is six hundred and thirty degrees Celsius. The combustion performance of the PC sheet reaches the flame retardant B1 level through the quality supervision and testing of fireproof building materials. In addition to the flame retardant properties of the polycarbonate sheet, it also has excellent chemical resistance. At room temperature, the polycarbonate sheet can withstand corrosion by organic acids, inorganic acids, weak acids, vegetable oils, neutral salt solutions, etc. Furthermore, the polycarbonate sheet has excellent heat and cold resistance, able to withstand changes in harsh weather conditions such as high temperatures and cold. The polycarbonate sheet also has a very high light transmittance, and the light transmittance is related to the color of the polycarbonate sheet. The impact resistance of the polycarbonate sheet is also very good, eight times that of ordinary glass. The outstanding feature of the polycarbonate sheet is of course safety. It will not shatter like glass, making it very safe and convenient to use.
Flame retardant level, which is the property that a substance has or material has after treatment that significantly delays the extension of flames, and distinguishes the level system based on this.
PC polycarbonate sheet belongs to engineering plastics, and the plastic flame retardant levels increase step by step from HB, V-2, V-1 to V-0:
1. HB: For samples with a thickness of 3 to 13 millimeters, the burning rate is less than 40 millimeters per minute; for samples with a thickness of less than 3 millimeters, the burning rate is less than 70 millimeters per minute; or extinguish before reaching the 100 mm symbol.
2. V-2: After two 10-second burning tests on the sample, the flame extinguishes within 60 seconds. Combustible material may drop.
3. V-1: After two 10-second burning tests on the sample, the flame extinguishes within 60 seconds. Combustible material may not drop.
4. V-0: After two 10-second burning tests on the sample, the flame extinguishes within 30 seconds. Combustible material may not drop.
Through experimental verification, we have found that PC polycarbonate sheet can self-extinguish within 30 seconds after the flame is removed, and the burning material does not drop, achieving the plastic UL94 standard flame retardant V-0 level, so you can rest assured to use it.
Selection of past standards
A Class: Non-combustible building materials that hardly burn.
A1 Class: Non-combustible, no open flame.
A2 Class: Non-combustible, must measure smoke, must pass.
B1 Class: Flame retardant building materials: Flame retardant materials have good flame retardant effects. They do not ignite easily in the air or under high temperature, do not quickly spread, and immediately stop burning when the heat source is removed.
B2 Class: Combustible building materials: Combustible materials have a certain flame retardant effect. They will ignite immediately in the air or under high temperature, and easily cause the spread of fire, such as wooden pillars, wooden roof frames, wooden beams, wooden stairs, etc.
B3 Class: Flammable building materials, without any flame retardant effect, easily ignite, and have a high risk of fire.
