��팘he conditions above are recommended conditions and are subject to change depending on the aging time and processing condition.
Processing conditions:
The process condition of ZEROPOL might be changed according to the particle size, the expandability, a kind of the equipment, aging time of materials, etc.
Main processing conditions are generally as follows.
Maturing Time < Tropical climate >:
Maturing time depends on the density, molding process, etc.
In case of 15~25g/�꼻 of density, it is required to mature for 6~18 hr.
In case of 25g~30g/�꼻 of density, from 16~28 hr .
Molding:
Molding is carried out with 2~3kgf/�렆 of pressure of saturated steam.
Molding process depends on both molding conditions and densities. It is controlled by a steaming time and pressure.
The cycle time of ZEROPOL is fast compared to the conventional white EPS. Moreover, it yields very well fused insulation boards.
Cutting:
The cutting wire of the molding product has to be used by a nichrome wire or an alloy of the nichrome.
The temperature of the cutting wire is generally 170 ~ 250�꼦.
Safety instructions:
Generally, ZEROPOL is not classified as a harmful or dangerous material.
However, caution needs to be taken in handling.
ZEROPOL products and the finished molding products should not be exposed to ignition sources in processing area and warehouse. Proper ventilation in all processing area is required to avoid accumulations of blowing agent.
