旭プレス工業 Company Profile

Promoting the zero-asbestos transition for gaskets. The era is shifting from non-asbestos to zero-asbestos.

Asbestos testing in Japan is conducted using the JIS method, which employs "X-ray diffraction" and "phase contrast and dispersion microscopy." However, this method has been criticized for its flaws, such as misidentifying other particles as asbestos and potentially missing asbestos content below 5%. Therefore, even products deemed non-asbestos in Japan may be determined to contain asbestos when tested using the polarized light microscopy (PLM) method, which is considered more reliable in Europe and the United States. To avoid such situations, a standard known as "Zero Asbestos," which ensures that products contain no asbestos and have passed tests using polarized light microscopy (PLM) and even more reliable electron microscopy, is gaining traction. In July 2012, an ISO asbestos analysis method was published, and the JIS method was excluded, accelerating this movement domestically. In anticipation of this trend, our company has obtained the trademark for "Zero As" and has promptly introduced testing using polarized light microscopy and electron microscopy. Since 1990, all of our products have been certified as Zero Asbestos, so you can use the "Zero As Gasket NAPI Series" with confidence.
