under high temperature and pressure, inject the PPR into wood material base board such as HDF or particle board to form a perfect plastic locking system .
Features of frame floor:
1. Separate the core board from the air, more water and moisture resistant, less shrinkage, expansion.
2. Plastic frame covered the core, formaldehyde emission is almost zero .
3. In warm weather area, frame floor will not go moldy like normal floors.
4. Plastic frame protect the core board from colliding, which is life-long last .
5. No squeaking .
Frame material: PPR = polypropylene random.
1. main component are H and C, poisonless .
2. heat and pressure resistance, under 20 centi degrees can use over 100 years .
3. heat preservation, only 1/200 of steel .
4. not expand, moister resistant, density is about 0.9g/cm3; very steady .
