Physical properties of materials and foaming lines
PS foam lines Material: PS stands for polystyrene foam particles through the secondary output of a product is defined by the polystyrene styrene monomer by free radical polymerization of synthetic polymers. It is a colorless, transparent thermoplastic, having a higher glass transition temperature of 100 deg.] C,
PS foam physical properties: polystyrene glass transition temperature of 80 ~ 90 ℃, the amorphous density of 1.04 to 1.06 g / cc, crystal density 1.11 ~ 1.12 g / cc, a melting temperature of 240 ℃, resistivity of 1020 ~ 1022 ohm-cm. 30 ℃ when the thermal conductivity 0.116 W / (m Kelvin). Usually polystyrene random amorphous polymer with excellent insulation, insulation and transparency, long-term use temperature of 0 ~ 70 ℃, but the crisp, cold easy to crack.
