PHOSPHORUS-BASED FIREPROOF FOAM BOARD
BYZHI IN is a fireproof material made using phosphorus-based flame retardants as the main component.Protect and enhance the fire resistance of flammable materials.It exists in the form of plates and strips.Under the influence of the fire, BYZHI IN rapidly produces a large amount of microporous insulating foam,Thus protecting the covered materials from the effects of fire.It seals the gaps caused by deformation.And prevent flames, smoke, and heat from penetrating between the two components.Types 5 and 15 are flexible, while type 36 is semi-rigid.Begins to expand at 180° C without generating expansion pressure, forming multidirectional expanding foam.Can be processed into special shapes, and the surface can be coated with double-sided tape for easy installation.This product should not be in prolonged contact with water.

USAGE SUGGESTIONS
1. PRODUCT MODEL AND APPLICABLE SCENARIOS
BYZHI IN5/IN15: Suitable for fire protection on flat or curved surfaces, and can be used to protect hardware, surface cases, hinges, and other components.
BYZHI IN36: Mainly used for edge sealing of larger components, such as sealing the gaps between door frames and door panels.
2. INSTRUCTIONS FOR USE
Cutting operation: Depending on actual requirements, select the appropriate size of sheet or strip material for cutting.
Installation requirements: The material should be installed tightly at gaps or edges of components to ensure effective foam insulation in the event of a fire.
Usage precautions: Avoid direct contact of the material with other chemicals to prevent affecting the foaming effect.
3. PACKAGING REQUIREMENTS
Sheet and strip materials are usually packed in moisture-proof plastic bags or vacuum packaging to prevent moisture absorption and packaging tear prevention during transportation.
4. TRANSPORTATION REQUIREMENTS
For large-scale transportation, waterproof wooden crates or cardboard boxes should be used to ensure the stability of the products during transit.
5. STORAGE CONDITIONS
Environmental requirements: Store in a dry, ventilated warehouse with temperature controlled between 5℃ and 30℃, avoiding high temperature and direct sunlight.
Stacking requirement: When stacking, avoid heavy pressure to prevent material deformation, which could affect subsequent usage.
Unused products: Products that have not been activated should be stored sealed to prevent contact with moisture and acidic or alkaline substances.
