興和化成 Product Lineup

At Kowa Kasei, we offer a wide range of products in addition to three types of noise protection tubes. - Noise protection sleeves - Noise protection mesh - Noise protection gaskets (square type) - Copper foil tape - Conductive fabric tape - Aluminum foil tape with masking - Laminated aluminum foil tape

Kowa Kasei's "Slide Lock Tube - Dust-Free Type" protects wiring from external dust. By using a resin film instead of a cross material for the sheet section, it prevents the generation of debris during cutting. The fitting part has a high degree of sealing, making it difficult for external dust to enter, and it can be easily attached using a dedicated slider. The sheet section has passed a dielectric strength test of 1200V, is equivalent to VW-1 for flammability, and plans to add an anti-static function. 【Features】 ■ Uses resin film for the sheet section ■ Size variations from 10Φ to 100Φ ■ Compliant with RoHS directives *For more details, please refer to the catalog or feel free to contact us.

Kowa Kasei's "Unravel-Resistant Slit Tube" is a wiring covering tube with a mesh design that prevents moisture and heat from accumulating inside. It is made of polyester threads woven in a lattice pattern to form a tubular shape, expanding 2 to 3 times its size when compressed to fit the covered object. Additionally, the cut edges are designed to be resistant to unraveling. 【Features】 ■ High flame resistance ■ Mesh material ■ Elasticity ■ Reduces internal heat accumulation ■ Size variations from a minimum diameter of 3Φ to 16Φ *For more details, please refer to the catalog or feel free to contact us.
