There was a request to attach a packing for water sealing on the rubber molded products, and I suggested using a highly waterproof tape called Eptsealer.

After prototyping a ring with a slit in one place, there were concerns about water leakage from the slit area, so we consulted about manufacturing the shape again. We proposed a new shape by adding a slit to the inner diameter of the ring to eliminate the joint, making it possible to adhere to rubber products as well. We received praise for our precise solutions to the concerns and the high level of our processing technology, and our processed products were adopted.

basic information

Recommended "Eptsealer" for water resistance, heat resistance, earthquake resistance, soundproofing, chemical resistance, etc. It is a highly flexible Eptsealer that shuts out vibrations, sound, water, and other elements by being applied to gaps in materials, products, and machinery. Made primarily of PDM rubber, it has heat resistance and chemical resistance (to acids and alkalis), boasting excellent performance among general-purpose rubbers. Thanks to superior foaming technology, it is a low-density and flexible foam material. The cell structure comes in two types: independent bubble type and semi-independent semi-continuous bubble type, allowing it to meet various demands through different foaming techniques. It performs well in areas exposed to intense impacts and vibrations, such as door mirrors, tail lamps, air conditioners, and door speakers.
