Product Composition
The composition of PP sheet is based on polypropylene, and through copolymerization modification and functional additives, it can achieve diversified performance requirements, such as light weight, high strength, corrosion resistance, high temperature resistance, etc.
Performance Characteristics
1. Lightweight and durable: The density is only 0.89-0.91g/cm³ (one of the lightest plastics), and the impact strength is significantly improved after copolymerization modification. It has strong resistance to bending fatigue and is suitable for packaging, automotive parts and other scenarios.
2. Heat and chemical resistance: High temperature resistance of 110-120℃ (short-term 150℃), acid, alkali, grease and solvent resistance.
3. Processing characteristics: High shrinkage (1.8-2.5%), but adding 30% glass fiber can reduce it to 0.7%; good melt fluidity, suitable for injection molding, extrusion and other processes, processing temperature 220-275℃.
4. Electrical properties and environmental protection: Excellent high-frequency insulation (water absorption rate is only 0.01%), but antistatic agent needs to be added; the material is 100% recyclable
Advantages
PP sheet has become an ideal material for packaging, industry, home appliances and other fields by virtue of its core advantages such as light weight, environmental protection and corrosion resistance, combined with flexible processing and modification capabilities. Its performance can be further optimized through copolymerization, filling, surface treatment and other technologies to meet diverse needs from food-grade safety to high-temperature flame retardancy.
Application Fields
Packaging: food trays, shockproof turnover boxes;
Advertisement: printable display boards, light boxes;
Architecture: soundproof ceilings, drainage boards;
Home appliances: air conditioner housings, washing machine parts (flame retardant, weather-resistant modification)

FAQ
1. Q: Is PP board environmentally friendly? What advantages does it have over wood boards and density boards?
A: Absolutely environmentally friendly! PP board contains no harmful substances such as formaldehyde and meets food-grade standards, making it suitable for direct contact with food. Wood boards/density boards are prone to releasing formaldehyde and are likely to deform and breed mold when exposed to moisture. Safer and more durable.
2. Q: How is the corrosion resistance of PP plates? Can it replace metal sheets?
A: It has extremely strong resistance to acid and alkali corrosion, far exceeding that of metals! PP plates can resist acid, alkali and salt corrosion in chemical storage tanks and will never rust. Metal plates (such as iron and aluminum) are prone to rust and require regular maintenance. Lower cost and longer lifespan.
3. Q: Is PP board lightweight? Is it convenient to move and install?
A: It weighs only 1/8 of steel and 70% of PVC board! With a density of only 0.9-0.91g/cm³, it can be easily moved and installed by a single person, significantly saving labor and time costs. It is especially suitable for large equipment or high-altitude operations.
4. Q: How is the water and moisture resistance of PP boards? Is it suitable for the humid environment in the south?
A: Water absorption rate is only 0.01%, completely moisture-proof! The bathroom cabinet and kitchen countertop do not deform after long-term soaking in water. Wooden boards tend to expand and mold when exposed to water, and metal plates are prone to condensation. The preferred material for the return of the south wind in the south.
5. Q: Is the strength of the PP board sufficient? Can it bear weight?
A: The strength of glass fiber reinforced PP board (FRPP) is 50% higher than that of ordinary PP board! The load-bearing capacity can reach 50kg per layer, which is superior to PE boards. By adding 20% glass fiber, its strength rivals that of metal, but it is lighter in weight. High load-bearing capacity and no deformation.
