1.Q:Is black PP board environmentally friendly and safe?
A: Yes! The black PP board is made of food grade polypropylene raw material, non-toxic and odorless, and meets national hygiene standards (such as GB 4806.6-2016). It can be safely used in food packaging, medical equipment and other scenarios. Compared to PVC (which contains chlorine and may release hydrogen chloride gas), PP is more environmentally friendly and harmless.
2.Q:What is the temperature resistance of black PP board? What about comparing ABS or PC?
A: Black PP board can withstand 100 ℃ for long-term use (120 ℃ for short-term use) and is suitable for high-temperature disinfection environments. Although ABS has slightly higher heat resistance (110-120 ℃), its cost is higher; PC has stronger temperature resistance (above 130 ℃), but it is expensive and prone to scratching. PP board has a better balance between cost-effectiveness and temperature resistance.
3.Q:Why choose black instead of light colored PP board?
A: Adding black carbon black masterbatch can increase UV protection by more than 50%, prolong outdoor service life (such as environmentally friendly equipment and automotive components exposed to sunlight), and provide light shielding suitable for electronic and optical equipment. Light colored PP is prone to aging and discoloration.
4.Q:What are the advantages of black PP board compared to PVC board?
A: Three core advantages:
Lightweight: PP density is only 0.9g/cm ³ (PVC is 1.4g/cm ³), making transportation more effortless;
Corrosion resistance: PP is resistant to strong acids and alkalis (such as electroplating equipment), and PVC is prone to brittleness when exposed to chemicals for a long time;
Safety: PP is non-toxic, PVC releases harmful gases at high temperatures.
5. Q:Is the black PP board flame retardant?
A: Yes! By halogen-free flame retardant modification (such as adding phosphorus nitrogen flame retardants), it can meet the UL94 V-0 flame retardant standard and self extinguish upon ignition. Although black is more difficult to achieve high flame retardancy than light colors (carbon black affects the density of the char layer), our process has overcome this challenge.
