What is Anchor-Free Seismic Restraint? It is a method used to secure equipment or machinery in locations where anchor bolts cannot be used for various reasons. Our seismic mat “NonBuren Tack Gel” offers strong adhesive properties, allowing sufficient seismic resistance without the need for anchor installation. Since the material itself is adhesive, its performance does […]

Lesser-Known Terms Related to Vibration Vibration isolation, Vibration elimination, Vibration control, Seismic Control, Earthquake resistance, Base isolation, Soundproofing, Sound absorption and Sound insulation. There are various terms related to vibration. All of these terms describe measures taken to address moving or shaking objects. Differences Between Vibrating and Trembling The terms "Vibration" and "Trembling" are used […]

About Vibration Vibration and shock isolation can be classified into two categories. Active Applications This involves preventing the transmission of vibrational or shock forces from machinery operations to the foundation. This is mainly achieved by placing anti-vibration materials, such as under vacuum pumps, to reduce the impact on surrounding areas. Passive Applications Thisinvolves preventing vibrations […]

What is Rubber? Rubber is a material that stretches and returns to its original shape, similar to a resin. The term "elastomer" is also used for materials that are stretchy and flexible, but in everyday use, these terms are often not distinguished. "Rubber" usually refers to traditional materials like natural rubber and older synthetic rubbers, […]

The NonBuren anti-vibration material has a certain level of hardness. It adjusts its hardness based on the vibration frequency to prevent vibrations. Please note that the data will vary depending on the hardness, as shown below. Frequency Dependency Data from using NonBuren Sheets S15 to S70 NonBuren shows a smooth, flat response across all vibration […]
