PP boards exhibit excellent performance in the field of corrosion protection, making them a key option for replacing traditional corrosion-prone materials in industries such as chemical engineering, environmental protection, and water treatment. They possess outstanding chemical stability and have good tolerance to most acid, alkali, salt solutions, and low-concentration organic solvents, being less likely to be eroded under normal temperature conditions. As non-metallic polymers, they do not undergo electrochemical corrosion and can maintain structural integrity even in humid and salt-foggy environments.
Meanwhile, PP boards have an extremely low water absorption rate (usually less than 0.01%), almost not absorbing water, which can effectively prevent indirect corrosion problems caused by the penetration of corrosive media. Their surfaces are flat and smooth, which can reduce the adhesion of corrosive media, lower the risk of local corrosion, such as pitting corrosion and crevice corrosion, and facilitate cleaning and maintenance.
Within the temperature range of -20℃ to 80℃, the corrosion resistance performance of PP boards remains stable, which is sufficient to meet the needs of most normal or medium - low temperature corrosion protection scenarios. Modified PP boards with added antioxidants and ultraviolet stabilizers have better anti-aging performance. In outdoor environments or those in long-term contact with corrosive media, their service life can reach more than 5-10 years, and the attenuation of their corrosion resistance performance during this period is gentle. In practical applications, PP boards are widely used in the production of chemical containers, environmental protection equipment components (such as desulfurization towers and waste gas treatment pipelines), water treatment facilities (such as sedimentation tank and filter tank linings), and electroplating tanks, all showing reliable corrosion protection effects.
According to the materials and features, the PP boards could be subdivided into:
| Characteristic | PP (Polypropylene) | PE (Polyethylene) | PVC (Polyvinyl Chloride) |
|---|---|---|---|
| Density (g/cm³) | 0.89-0.91 | 0.91-0.96 (Higher for HDPE, lower for LDPE) | 1.3-1.45 |
| Appearance | Translucent to opaque, relatively hard surface | Translucent to milky white, soft surface with waxy feel | Transparent to opaque, diverse colors (pigment-addable) |
| Hardness | Medium-high, good rigidity | Low (LDPE) to medium (HDPE), good flexibility | Medium-high (rigid PVC); flexibility of soft PVC is adjustable |
| Impact Resistance | Good at room temperature, brittle at low temperatures | Excellent, especially tough at low temperatures (LDPE better) | Poor for rigid PVC at low temperatures; soft PVC has improved toughness due to plasticizers |
| Tensile Strength (MPa) | 20-40 | 8-30 (Lower for LDPE, higher for HDPE) | 30-50 (rigid PVC), lower for soft PVC |
| Continuous Service Temperature (℃) | 110-120 | -40-80 (About 60 for LDPE, about 100 for HDPE) | -15-60 (rigid PVC), lower for soft PVC (affected by plasticizers) |
| Low-Temperature Resistance | Poor, brittle below 0℃ | Excellent, can withstand below -70℃ (HDPE slightly less cold-resistant) | Poor, easy to harden and crack at low temperatures |
| Vicat Softening Point (℃) | 150 | 105-130 (Higher for HDPE) | 75-90 (rigid PVC) |
| Acid and Alkali Resistance | Excellent, resistant to most acids, alkalis, salts; not resistant to aromatic solvents | Excellent, resistant to acids and alkalis; not resistant to strong oxidants and organic solvents | Resistant to general acids and alkalis; not resistant to concentrated acids, aromatics, and ketones |
| Solvent Resistance | Poor (easily dissolved by aromatics and chlorinated hydrocarbons) | Medium (LDPE more easily swollen by solvents) | Medium (rigid PVC better than soft PVC) |
| Processing Temperature (℃) | 170-220 | 150-200 (Lower for LDPE, higher for HDPE) | 160-190 (requires stabilizers to prevent decomposition) |
| Weldability | Easy to weld, suitable for heat sealing and ultrasonic welding | Easy to weld, LDPE better than HDPE | Rigid PVC weldable; soft PVC poor due to plasticizer migration |
| Molding Methods | Extrusion, injection molding, blow molding, etc. | Extrusion, injection molding, blow molding, film forming, etc. | Extrusion, injection molding, calendering (soft PVC suitable for films, pipes) |
| Insulation | Excellent, low dielectric constant, good high-frequency insulation | Excellent, low dielectric loss, suitable for high-frequency insulation | Good, but rigid PVC better than soft PVC (affected by plasticizers) |
| Toxicity | Non-toxic, meets food contact standards | Non-toxic, meets food contact standards (pure PE) | Rigid PVC itself non-toxic but may contain lead stabilizers; soft PVC contains plasticizers (phthalates may be harmful) |
| Recyclability | Easy to recycle, can be reprocessed | Easy to recycle, HDPE has higher recycling rate than LDPE | Difficult to recycle, recycled material has significant performance degradation |
| Typical Uses | Food packaging, pipes, auto parts, medical devices | Films (plastic bags), containers, pipes, toys | Pipes (drainage), profiles (doors/windows), films, artificial leather |
