According to the standard of ROHS EU, low temperature rising, low power consumption and high flame-retardant. PC alloy is used as the material of environmental protection. The low temperature rising is less than 15K (far less than 25K required by the National Standard) . The power consumption of the whole machine is less than 0.5 W (12W for the same kind of products) . The hot deformation temperature of the end-box with high flame-retardant is 960 ° C and up to 200 ° C (150 ° C for the same kind of products)
