Product Description:
Mine-specific polyester polyols are functional polyols designed for the special needs of the mining industry. They are mainly used to prepare polyurethane materials that are wear-resistant, flame-retardant, anti-static and corrosion-resistant, in order to meet the safety and performance requirements in harsh underground environments (such as high humidity, high impact, flammable and explosive gases, etc.).
Application:
1) Mining conveyor systems
• Conveyor belt coating: Polyurethane elastomer coating replaces traditional rubber, extending service life by more than three times.
• Drum rubber coating: Anti-slip, noise reduction, and excellent dynamic impact resistance.
(2) Underground protective materials
• Seals and gaskets: Hydraulic support sealing rings, pipe joints, resistant to high pressure (>30MPa) and coal dust erosion.
• Explosion-proof electrical encapsulation: Flame-retardant potting compound for switches and sensors (compliant with GB 3836 explosive environment standards).
(3) Support and shock absorption
• Mining polyurethane foam: Used for tunnel filling (fast curing, high load-bearing capacity), or as shock absorption layers for equipment.
Parameters:
| Product Model | Hydroxyl value (mgKOH/g) | Acid Value (mgKOH/g) | Moisture (%) | Viscosity (CPS 25℃) |
| KXF-350 | 350±20 | ≤2.0 | ≤0.1 | 1500±500 |
| KXF-280 | 280±15 | ≤1.5 | ≤0.1 | 1000±200 |
Package:
It is packed in 200 liter iron drum, net weight 225kg.
Storage:
Please store in a cool, ventilated place.
