To ensure quality in pvc plastic foam board, pvc foam board waterproof, wooden colour pvc sheet, laminated pvc foam board, and pvc expanded foam board, here are quick methods to check for purity:
Visual Inspection: High-purity boards have smooth, even color with minimal defects. Uneven patterns or discoloration may indicate impurities.
Density Check: Pure PVC boards feel denser and sturdier, while impure boards may be lighter due to added fillers.
Chemical Testing: Techniques like FTIR and GC-MS reveal additives or impurities, confirming the board’s quality for specific uses.
Fire Resistance Test: Pure PVC is more flame-retardant. Burning a small sample can show purity; impure boards burn faster.
These methods help ensure that PVC boards meet durability and aesthetic requirements.
