Can the PC endurance board last for more than one hour?

1. The PC board cannot burn for more than an hour. Flame retardant rating, that is, the rating system classified according to the property of a substance or a material after treatment that significantly delays the spread of flame. PC endurance board belongs to engineering plastics, and the flame retardant level of plastics increases step by step from HB, V-2, V-1 to V-0: HB: the lowest flame retardant level in the UL94 standard.

2. Seconds; for each set of 5 samples, after 10 ignitions, the total burning time with flames did not exceed 250 seconds; no sample burned all the way to the fixture (including burning with flames and burning with redness); The droplets of the sample were allowed to burn and melt to ignite the cotton in the next 12 places, but the cotton burned for a short time; no sample continued to burn red for more than 60 seconds after removing the test flame for the second time.

3. Embrittlement temperature: The embrittlement temperature of pc endurance board is-40℃, and the minimum continuous use temperature is-30℃, which is better than most plastics. Flammability: pc endurance board is one of the refractory and self-extinguishing plastics and will not release toxic gases when heated at high temperatures. Thermal conductivity: The thermal conductivity of pc endurance board is not much different from that of ordinary plastics. It is 1/4 of glass, 1/300 of iron, 1/1000 of aluminum, and 1/2000 of copper. It is one of the materials with excellent thermal insulation properties.

Is the endurance board a PC board? Why is the endurance board I bought so fragile and flammable?

1. Endurance boards are usually made of polycarbonate (PC) material, which has good toughness and impact resistance. Some people think that acrylic plates are fragile, but in fact, high-quality endurance plates are not fragile, and they usually have good impact resistance. Endurance boards are fire-resistant materials that extinguish themselves when exposed to a fire source rather than burning immediately.

2. Endurance boards are made of PC material. Generally, acrylic is very fragile. Endurance boards are not fragile and are fire-proof materials. They will self-extinguish after encountering fire. You have to make sure whether you are buying a PC endurance board.

3. PC board is a plastic board made of polycarbonate resin. It can be a solid or hollow structure and has a variety of different thicknesses. Endurance board is a special type of PC board that is usually a solid structure with higher density and strength. Performance differences: Endurance boards have excellent impact resistance and can withstand the impact of natural disasters such as hail, storms, etc., and are not easy to rupture or deform.

4. This characteristic makes endurance boards widely used in fields such as architectural lighting and advertising light boxes. Although ordinary PC boards also have certain impact resistance and light transmission, they are slightly insufficient in comparison. Price difference: Since endurance boards have better performance and more complex production processes, their prices are usually higher than ordinary PC boards. For example, an endurance board of the same thickness may cost twice or more than a regular PC board. Therefore, when purchasing, trade-offs need to be made based on actual needs and budget.

How to identify PC endurance boards, acrylic boards, PS organic boards, and MS boards?

1. PC endurance board, acrylic board, PS organic board, and MS board can be identified by observing appearance, combustion characteristics, physical properties, etc. The details are as follows: Classification and appearance of acrylic board: divided into extruded board and cast board. Extruded plate has good transparency; cast plate has high transparency. Burning characteristics: Extruded board: When the fire burns, the flame is clear, there is no smoke, there are bubbles, and the filament can be pulled out when extinguishing the fire. Cast plate: There is no smoke, bubbles and squeaks when burning, and no silk when extinguishing the fire.

2. Identification method for acrylic plexiglass plates There are many types of acrylic plexiglass plates on the market, including extruded plates, cast plates and other similar plastic plates such as PC endurance plates, PS organic plates and MS plates. In order to accurately identify acrylic plexiglass plates, the following are some key identification methods: Identification of acrylic plates (plexiglass) Transparency of extruded plates: The transparency of extruded plates is higher.

3. When burning with fire, a large amount of black smoke will be produced. PC endurance boards are good at impact resistance and cannot be broken. When burned with fire, they are flame retardant and will emit some black smoke. Different nature. When the PS organic board is burned with fire, it is smoke-free, has bubbles, and has a squeaking sound, and has no silk when extinguishing the fire. When the PC endurance board is burned with fire, it is smoke-free, has bubbles, and has a squeaking sound, and has no silk when extinguishing the fire. There are also identification methods such as acrylic plate (plexiglass) MS plate.
