Product name:Good Quality Perlite Fireproof Fire Door Core
1.Description
OCM Fire Door Core board with thickness from 3mm to 25mm,can be applied in every part of a fire door.
The Diversity, non-combustibility, insulation and timber-like properties make OCM Fire Door Core board ideal for fireproof or fire retardant door frames, door panels, door studs, substrates, decorative boards of fire doors.It does not warp, or distort while continuous exposure to open fire for testing , prior to physical disintegration.
2.Component
•Using Magnesium Sulfate (MgSO4) instead of magnesium chloride , which makes the board Anti halogenation and also solve the rust problem.
•Made of mineral magnesium oxide, magnesium sulfate,(Mgoso4) Fiber glass, Perlite etc.
3.Features
•Outstanding fire behavior meet 30mins to 270mins.
•Lightness
•Stiffness
•A1 Incombustible level
•Durability
