• Glass

The glass wool insulation material we provide uses acrylic resin that does not contain formaldehyde as a binder, making it a very safe glass wool in terms of environmental and health impacts. Additionally, the diameter of the glass fibers used is 5 to 6 micrometers, which is finer than conventional products, significantly improving insulation performance and possessing excellent characteristics. It is recommended for clients and construction companies who want to achieve a higher level of safety and insulation performance while keeping material and construction costs down. Please widely adopt it as insulation material, sound-absorbing material, and thermal insulation material for houses and buildings in general. We also accept wholesale sales and OEM production.

• Refrigerators and freezers

Colored sand is made from silica sand, using a mixture of ceramic and high-temperature toner on the surface, and is fired at high temperatures of 800°C or more. It has excellent heat resistance, weather resistance, and chemical resistance, and is widely used as colored aggregate in the fields of construction and civil engineering, as well as in various areas such as landscaping, gardening, and sand art.
