Phenolic resin foaming material for coal mine filling and sealing
Product Description:
The A and B components of phenolic resin foaming materials for coal mine filling and sealing have a certain volume ratio (1; 1~4:1) can quickly polymerize into insoluble polymer foam after uniform mixing. This foam has excellent flame retardant properties, high expansion rate and low reaction temperature, making it particularly suitable for large volume filling.

Product Use:
The phenolic resin foaming material for coal mine filling and sealing is suitable for various hollow filling, roadway closure and other fields of mines, tunnels and other projects, and plays a role in isolating air, sealing gas and reinforcing to a certain extent. Low-viscosity hybrid resins can quickly diffuse, penetrate into large and small voids or cavities, and quickly foam and cure into highly flame retardant foams with foaming rates of 25-30 times or more.
Features:
The non-meltable polymer foam material polymerized by homogeneous mixing of phenolic resin foaming material AB component for coal mine filling and sealing with a predetermined volume ratio has the following characteristics:
1. The flame retardant performance meets the requirements of MT113-1995, and the oxygen index >35%;
2. Excellent solvent resistance and corrosion resistance;
3. The heat of internal reaction is small;
4. The viscosity of the material is low and the permeability is strong;
5. Excellent antistatic performance;
6. The construction is fast and convenient;
Packing:
Two-compoent liquid, 25 plastic drum
