20mm Food Grade PP Wall Sheet Hollow Board with 0.9 g/cm³ Density and 120°C Temperature Resistance

20mm food-grade PP wall sheets offer exceptional corrosion resistance and durability for construction applications. These lightweight polypropylene hollow boards provide superior moisture protection and impact resistance, making them an ideal alternative to traditional materials like wood, metal, or glass.

With water absorption of only 0.01%-0.03%, these PP boards provide superior moisture protection compared to wood (12%-18%) and standard plastic boards (0.5%-1%). The dense molecular structure ensures dimensional stability in humid conditions.

• Ideal for kitchens, bathrooms, and basements
• Resistant to acids, alkalis, and salt spray
• Smooth surface prevents mold growth
• Food-grade material with no formaldehyde
• Lightweight design (1/8 the weight of steel)

Featuring elongation at break of 400%-600%, these boards absorb impact energy through deformation rather than fracture. Maintains performance from -20°C to 80°C with surface hardness of R80-R100.

• Suitable for outdoor applications and cold climates
• Resists daily wear and scratches
• Local damage can be repaired without full replacement
• Reduces structural load for safer installation

These corrosion-resistant PP wall sheets are widely used in chemical processing plants, food facilities, and industrial environments where moisture protection and chemical resistance are critical requirements.
