Gundle Sheet FPA<\/h4>\n\n\n\n

This sheet is a blend of polypropylene and vulcanized rubber. The flexibility component is micro-dispersed during the polymerization stage, resulting in homogeneous and stable performance. Compared to general synthetic resin impervious sheets, it shows less dimensional change with temperature change, and is less susceptible to temperature change during installation, summer, and winter.<\/p>\n\n\n\n

TPE Sheet (PE-based)<\/h4>\n\n\n\n

Thermoplastic rubber sheets are mainly made from thermoplastic rubber obtained by copolymerizing \u03b1-olefins (which do not have unstable double bonds in their molecular structure). It is also called \u201cthermoplastic rubber sheet\u201d because it is not easily affected by flooding water or microorganisms.<\/p>\n\n\n\n

Self-propelled welding situation<\/h4>\n\n\n\n

Self-propelled fusion bonding machines are mainly used to fuse impervious sheets. Pressure is applied while the sheets are heated by a hot plate or hot air to unify overlapping sheets.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Pressure test status<\/h4>\n\n\n\n

The watertightness of the joint is inspected by applying pressure to a predetermined value through the inspection hole in the center of two rows of joints (double seam method) and measuring the amount of pressure reduction.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Extrusion welding status<\/h4>\n\n\n\n

Extrusion welding is used for joints that are difficult to install with a self-propelled fusion splicer. Using a dedicated welding machine, cuttings of the same material as the impervious sheet are melted and integrated with the sheet.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n
