Abstract This research subject to replacement a low density compressed sheet manufacturing process, eco-friendly process system designing with goods development what used at industrial engine, automotive, pipeline applicable compressed jointing gasket. The gasket is defined as static seals that prevents leakage by fasten the bolts between the pressurized vessel or flanges. And a gasket is selected each of applicable condition depend on type of fluid, pressure, temperature with different shapes or materials. The current manufacturing method to make a compressed jointing gasket is to mixing with melting rubber to improve viscosity by organic solvent (toluene) with variety fiber and inorganic filler to increases filling the density. This compressed jointing manufacturing process suitable for satisfying properties such as tensile strength, density, compressibility, recovery, creep relaxation, maximum continuous temperature, resistance to fluid, and resistance to fuel. However, the gasket manufacturing method using solvent is not effective in terms of solvent recovery and workability. Recently, for foreign products, including advanced countries, the method of producing environmentally friendly solvent free products has been on the rise. This research is aim to development not only environmentally friendly production method by water and water-soluble binder without the use of organic solvents but also using a pulper what current exist papermaking process for securing the gasket manufacturing technique with dispersion of raw material, condense of slurry. By the different slurry density of paper and gasket, we study to find perfect condition at dewatering and dry condition to make sheet. And also, to find the optimize combination at material structure between lots of filler and fiber, the study proceeding and the analyzed.
