Why do polyurethane sheets and rods have bubbles?
Polyurethane sheets and rods are widely used due to their excellent mechanical properties. However, some polyurethane products may have bubbles inside. This is because the production process of polyurethane sheets and rods is the pouring type, which is prone to bubbles during the pouring process. We also treat eliminating bubbles as a major issue. On the one hand, we improve the production process and use a centrifuge to mold polyurethane sheets. During the production process, it rotates at high speed, and most of the bubbles are squeezed out. On the other hand, we can briefly roast it with fire to eliminate most of the remaining bubbles.
Our company, Shandong Xinruituo Precision Industrial Co., Ltd., specializes in the production of polyurethane sheets and rods. We have our own raw materials, excellent quality, and high cost performance. If you need it, please feel free to contact us for consultation.
