Phenolic Resin Foaming Material For Coal Mine Filling And Sealing
Phenolic resin foam material for coal mine filling and sealing has excellent flame retardant properties, high expansion ratio and low reaction temperature, and is particularly suitable for large volume filling.
Product Introduction
After uniform mixing of Component A and B of phenolic resin foaming material for filling and sealing in coal mine at 1:1 volume ratio, the material rapidly polymerizes into an insoluble and infusible polymer foam. This foam exhibits exceptional flame retardancy,
high expansion ratio, low reaction temperature, which is Ideal for large-volume filling.
Product Usage
Phenolic resin foaming material for filling and sealing in coal mine are widely used in cavity filling, roadway sealing, and other engineering applications in mining and tunnel construction. They provide air isolation, gas sealing, and structural reinforcement. Low-viscosity resin blends can rapidly permeate and diffuse into voids and cracks of varying sizes, then expand and solidify into the highly flame-retardant foam with an expansion ratio of 25–30× or higher.
Product Features
The insoluble and infusible polymer foam formed by uniformly mixing Component A and B of phenolic resin foaming material for filling and sealing in coal mine at the predetermined volume ratio exhibits the following characteristics:
- Complies with MT113-1995 standard requirements,Oxygen index>35%
- Excellent resistanceto solvents and corrosion
- Low internal reaction heat
- Low viscosity and high permeability:
- Effectiveanti-static performance
- Rapid and convenient construction

Usage Precautions
For the application of Phenolic resin foaming material for filling and sealing in coal mine, appropriate construction equipment should be selected, including mixing pumps and spray guns. Prior to construction, ensure calibration of the grouting equipment to verify the component mixing ratio and mixing pressure.
Before commencing formal construction, the buyer must conduct material reliability tests under conditions identical to the actual construction environment to verify the applicability of the composite materials.
Storage (Usage) Precautions
The composite material should be sealed and stored at room temperature (15°C to 20°C), well-ventilated, and shaded area. Avoid direct sunlight or long-term storage above 30°C, which may reduce foam performance.
Expiration Date
Under suitable storage conditions, the storage period of polyurethane material for consolidating coal and rock at coal mine is 3 months.
Safety Precautions
Direct contact with the material may cause moderate eye irritation and mild skin irritation, potentially leading to skin allergies. Repeated inhalation of high-concentration vapors can induce respiratory allergies. Immediate medical attention should be sought, and anti-inflammatory and anti-allergic symptomatic treatment measures should be administered.
During operation, exercise caution to prevent direct contact with skin or splashing into eyes. Wear necessary protective equipment (gloves, protective goggles, work clothes, etc.).
In case of skin or eye contact, rinse immediately with clean water for at least 15 minutes. Wash the skin with soapy water and seek medical attention if necessary. If accidentally ingested, seek immediate medical treatment for symptomatic management.
Fire and Explosion Hazards
This product is not classified as flammable liquids, explosives, oxidizers, corrosives, toxic substances, or radioactive hazardous materials during storage and transportation. It is not categorized as a hazardous product.
Carbon dioxide, foam, or chemical dry-powder fire extinguishers can be used. If no other fire-extinguishing agents are available, a large amount of water mist can be sprayed. Once the fire is extinguished, the spilled materials must be thoroughly cleaned (refer to the “Spill and Leakage Handling” section).
Fire-Fighting Procedure: Standard protective measures.
Spill and Leakage Handling
Small amounts of leaked or spilled materials can be rinsed away with water. In case of large-scale leakage, contain and recover the materials, and wash the contaminated ground with water or detergent. The disposal of waste composite materials must comply with the local government’s environmental protection regulations.
