HPL Door details:
HPL is composed of several layers of doors sheet made of fibers (eg, paper) impregnated with resin operating in heat (heat-cured) which is influenced by the temperature and pressure of 5MPa stuck together. In making Formica sheets or the HPL of kraft paper, decorative paper, phenolic resin, melamine resin used.
- HPL with melamine HDF door are actually two versions of the MDF, HDF are less expensive. Because HP L doors because of melamine do not need to be painted and thus the premium paint above the door that there were two models of this type deducted doors.
- Due to the high-speed mass production projects that need to be achieved in the shortest possible time delivery doors HPL doors are most commonly used.
1. HPL thermal resistance:
HPL tolerate temperatures up to 180 ° C thermal shock is dry. HP L resistance (HPL) heat-cigarettes remain without effect on melamine sheets HPL sheets at high temperatures as well as dimensional changes of less than 3 percent.
2. The other of resistance HPL:
Due to the use of phenolic resin binder in the production of sheets of HP L (HPL) is resistant to the flow of electricity and the use of melamine resin glue on the surface layer makes surface resistance against weak acids,.
