発生しなかったものである。From these results, heated toilet seats made of foamed ABS resin are: (1) light in product weight, (2) short in time for the surface temperature to reach a predetermined temperature, and (3) less prone to peeling of the electrical charge mounting part during injection molding. was less likely to occur. Regarding this, (1) above is due to the small specific gravity of the foamed ABS resin,
(2) ABS resin shows a thermal conductivity of 0.23KcaJ/m・h・℃, while foamed ABS resin shows a thermal conductivity of 0.08K.
This is because it shows a thermal conductivity of "C", which prevents the heat emitted from the heating element from being transferred to the back surface, and allows more heat to be transferred to the skin layer.
Since the resin can be molded at low pressure, there was no peeling of the electrode mounting area.
