Gasket Packing Q&A No. 6

Gasket Packing Q&A No. 6

Is there a material that can improve the creep phenomenon of Teflon?

Daiko Corporation will answer your questions regarding gaskets and packing. 〇 Creep Phenomenon It is known that fluoropolymer-based gaskets experience significant decreases in bolt axial force due to creep relaxation characteristics. This reduction in bolt axial force raises concerns about sealing performance, and the risk of leakage accidents increases due to internal pressure loads and external forces from earthquakes, making it necessary to properly manage bolt axial force through re-tightening. 〇 Countermeasure Products We offer gaskets that improve creep resistance by mixing PTFE with special inorganic fillers that have corrosion and heat resistance, suitable for use up to 200°C. Representative products include Vulcan's V7020 and Nichias's T9007LC. They are resistant to almost all fluids except for hydrofluoric acid and strong alkalis. We have stock in sheet form and can process it to your specified dimensions.

Daiko Tokyo Branch Processing Example No. 2 Gaskets and Industrial Products!

Daiko Tokyo Branch Processing Example No. 2 Gaskets and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We utilize various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. 【Processing Example】 〇 Neoprene rubber 3mm φ2325 x φ2072 bolt hole processing. Since the processing size is larger than the width of the material, we performed split processing with a water jet and then joined the pieces with adhesive. Large diameter processing can also be efficiently cut using water jet processing. Please feel free to inquire about the types of adhesives and methods of adhesion! Our experienced staff will assist you.

We utilize various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. We processed 100 tons of white sponge S35. Although it is a simple process to shape it into a donut, we cannot achieve a clean finish with a die cutter due to insufficient blade height. However, with a water jet, the processing surface can be finished vertically, eliminating the taper on the cross-section caused by die cutting.
