Will low temperatures cause brittle fracture in PP hollow sheets?
As one of the most important sheet materials, PP hollow sheets have a wide range of applications. Many types of sheets tend to become brittle and prone to fracture easily in cold weather. So, will PP hollow sheets also become brittle and fracture at low temperatures?
PP hollow board sheets exhibit excellent cold resistance; typically, even in frigid weather, PP sheets do not become brittle and crack. Because PP hollow boards have significantly higher ductility compared to other types of boards, they are less likely to experience crystal freezing in cold weather, thus preventing brittle fracture. Moreover, PP hollow boards also possess relatively high strength and hardness, enabling them to perform exceptionally well even in low-temperature conditions. In addition to their ability to function normally in low-temperature environments, PP hollow boards offer the following advantages:
1. Antistatic, Conductive, and Flame-Retardant Properties: By employing methods such as modification, blending, and surface coating, plastic hollow boards can be endowed with antistatic, conductive, or flame-retardant properties.
2. Excellent Mechanical Properties: The special structure of plastic hollow boards gives them outstanding mechanical properties, including high toughness, excellent impact resistance, high compressive strength, superior cushioning and shock absorption, high rigidity, and good bending performance.
3. Lightweight and resource-efficient: Plastic hollow boards boast excellent mechanical performance. To achieve the same results, using plastic hollow boards requires less material, incurs lower costs, and is significantly lighter in weight.
4. Chemically stable: Plastic hollow boards offer significant advantages over cardboard and wooden boards in terms of water resistance, moisture resistance, corrosion resistance, insect resistance, and the elimination of fumigation requirements. Thanks to the special molding process used for plastic hollow boards, any color can be achieved through the use of color masterbatches, and their surfaces are smooth and easy to print on.
