Description

1. An overwhelming impact resistance performance of a hokoru, New Material, and adopts kuriagarasuseramikku
High strength protection, a common filter used in the chemical, depending on kuriagarasuseramikku is a special formula for people with tempered glass is reinforced by chemical processing surface, only the glass interior to a kind of mineral called Ruby Spinel of fine crystal by 析出 by heat treatment, the material the interior prop uniform and reinforced. This makes it more than just your chemically tempered glass with hardness and flexibility over safaiakurisutarugarasu protective filter gets a lot of nature that is ideal as a material. Also, keep in cracks may be difficult to spread the properties and reduce likelihood the payload of tomorrow and in case you need safety and care.
● Hard to be scratched
To achieve the hardness is HV700 firmness Vickers. High strength protection, a common filter used in the Far Exceed chemically tempered glass Hardness makes it be a cause of the scratches and to prevent slipping.
● More than 10 times compared to conventional general protector, compared to common chemical tempered glass and 3 times more strength
New material depending on the fine crystal with a special formula to 析出 Ruby Spinel Inside kuriagarasuseramikku, glass, Hardness is the Vickers hardness HV700 to achieve. The same thickness of tempered glass used to make this high strength chemical protective filter compared to more than 3 times, it is 10 times more compared to conventional protective filter in strength.
