Core Performance
With a dense molecular structure and no pores, PP board can completely block water penetration. It will not absorb water, expand, deform or rot even in long-term contact with water or humid environments, and its waterproof effect is far superior to traditional wood and paper-based covering materials. It can withstand common corrosive media such as weak acids, weak bases and salt spray. In scenarios where chemical liquids may splash, it can prevent the covering material from being damaged by corrosion and thus losing waterproof function. Moreover, it has certain impact resistance and toughness, and is not easy to crack when hit by external forces. Meanwhile, it has a relatively wide temperature resistance range (usually -20℃~120℃), so its waterproof performance will not easily degrade under outdoor exposure or low-temperature freeze-thaw environments.
Advantages
PP (polypropylene) is a general-purpose plastic with sufficient raw material supply and stable prices. Compared with waterproof materials such as stainless steel plates, aluminum alloy plates and PVC hard plates, the basic unit price of PP sheets is usually 15%~30% lower. With a density of only 0.9g/cm³ (about 1/8 of steel), it is lightweight, making transportation and handling more labor-saving. Moreover, it is easy to cut, drill and weld without complex processing equipment. Its installation efficiency is more than 40% higher than that of metal waterproof plates, which indirectly reduces labor costs. Its service life can reach 5~10 years, and no frequent maintenance or replacement is required during this period. Compared with covering materials that need regular waterproof coating, its long-term comprehensive cost is lower.
Applications
Waterproof covering for the roof of temporary construction dormitories and material warehouses, or waterproof liners for enclosure walls, PP board enables quick construction with reliable waterproof performance. Waterproof liners at the bottom of kitchen cabinets and the back of bathroom vanities to prevent cabinet erosion by wall moisture or standing water; it can also be used as lightweight waterproof partitions for dry-wet separation in bathrooms. Also, it could be used as waterproof seam-filling material at the corners and joints of greenhouses, or waterproof liners for small seedling boxes, to prevent leakage of condensed water inside the greenhouse. Wrapped around the interfaces and valves of outdoor irrigation pipes to form waterproof protective covers, PP boards prevent rainwater from rusting equipment parts.
Comparison of building materials
| properties | PP Sheets | Wood | Metal | Glass |
| Weather Resistance | Excellent; withstands rain, UV (with stabilizers), and temperature fluctuations | Susceptible to rot, mold, and warping in moisture; requires treatment for outdoor use; vulnerable to UV damage over time | Resistant to rain and UV but may corrode in humid or chemical-exposed environments (e.g., steel rusts without coating) | Highly resistant to rain and UV but prone to shattering from extreme temperature changes |
| Weight | Lightweight, reducing transportation and installation effort | Moderate weight; varies by wood type | Heavy, increasing structural load and transportation costs | Heavy, requiring strong support structures |
| Chemical Resistance | Resists corrosion from common construction chemicals (cleaning agents, concrete additives) | Vulnerable to chemical damage from cleaning agents and moisture-related decay | Susceptible to corrosion from acids, salts, or harsh chemicals (unless coated) | Resistant to most chemicals but can be etched by strong acids |
| Cost-Effectiveness | Low material and maintenance costs compared to alternatives | Moderate material cost; high maintenance (treatment, repairs) over time | High material and fabrication costs; maintenance costs vary by type (e.g., steel needs anti-rust treatment) | High material and installation costs; expensive to replace if damaged |
| Versatility | Easily cut, welded, or bent into custom shapes | Can be cut and shaped but requires skilled craftsmanship; limited by natural grain and strength | Moldable into various forms but requires specialized equipment for cutting/welding | Can be shaped during production but difficult to modify post-installation |
| Moisture Resistance | Does not rot or swell when exposed to water; suitable for damp environments | Absorbs water, leading to swelling, rot, or decay without proper sealing | Prone to rusting in moist conditions (unless galvanized or coated) | Impermeable to water but edges/seams may leak if not sealed |
