Sound Absorbing Aluminum Plate

1. Melt temperature: The melting temperature of PC endurance board is 135 °C, and its continuous use temperature is up to 120 °C. 2. Linear expansion coefficient: The linear expansion coefficient is 7×10-5cm/cm/°C, which is small in plastics. 3. Embrittlement temperature: The embrittlement temperature of PC endurance board is -40 °C, and the minimum continuous use temperature is -30 °C, which is incomparable with general plastics. 4. Flammability: PC endurance board is one of the flame-retardant self-extinguishing plastics, which will not produce toxic gases when heated at high temperatures.
