How can you tell the quality of PP hollow boards?
Compared to conventional cardboard, PP hollow boards offer advantages such as moisture resistance, corrosion resistance, and lighter weight. They are now widely used across various industries. However, the quality of PP hollow boards on the market today varies considerably. So, how can we distinguish between high-quality and low-quality PP hollow boards?
Like all other products, PP hollow boards vary in quality—from high to low. Moreover, there are numerous manufacturers of hollow boards on the market, making it difficult to standardize product quality. Although it’s true that you get what you pay for, customers still want to spend the least amount of money possible while obtaining the highest-quality products. Below, Yourong Technology would like to share some tips for assessing the quality of PP hollow boards:
Color: First, examine the color of the hollow plastic sheet. High-quality plastic hollow sheets have bright, glossy colors, and sheets of the same color exhibit uniformity without any color variations. If you hold the plastic hollow sheet in a well-lit area and notice that its color appears dull or leans toward grayish-white, it’s possible that the raw materials used to manufacture this hollow sheet are problematic.
Density: Generally speaking, the denser a board is, the better its quality will be. Take two hollow plastic boards of the same size and hold them in your left and right hands respectively. If you give them a quick shake, the one that feels heavier in your hand is likely to be of higher quality. The greater the density, the better its impact resistance will be.
Physical Properties: Take a small piece of plastic honeycomb board and fold it in half by hand. A board that’s resilient is of higher quality, better able to handle various situations during use, and has a longer service life. On the other hand, boards that are hard, brittle, and prone to breaking—or those that are overly soft—are not ideal.
The above are several simple and quick ways to assess the quality of PP hollow boards. These methods allow you to make a rough judgment on the quality of the hollow boards. If you plan to purchase large quantities of high-quality plastic hollow boards, we recommend using professional testing equipment to accurately analyze their quality.
