在 PVC 擠出低發(fā)泡制品中添加發(fā)泡調(diào)節(jié)劑，能促進 PVC 的凝膠化，提高熔體的熱強度及延伸性；改善制品的表面質(zhì)量；使發(fā)泡劑形成的細(xì)微泡孔穩(wěn)定，不使泡孔壁破裂而相互穿透而形成大孔，故所得的泡沫不僅密度小而且強度好。
Adding foaming regulators in low-foamed PVC extrusion products can promote the gelation of PVC, enhance the thermal strength and extensibility of the melt; improve the surface quality of the products; stabilize the fine cells formed by the foaming agent, preventing the cell walls from breaking and penetrating each other to form large holes. Therefore, the resulting foam not only has a low density but also good strength.

Product performance
一是為了促進PVC的塑化;
One is to promote the plasticization of PVC;
二是為了提高PVC發(fā)泡物料的熔體強度，防止氣泡的合并，以得到均勻發(fā)泡的制品;
Secondly, it is to enhance the melt strength of PVC foaming materials, prevent the merging of bubbles, and obtain uniformly foamed products.
三是為了保證熔體具有良好的流動性，以得到外觀良好的制品。
Thirdly, it is to ensure that the melt has good fluidity, so as to obtain products with good appearance.

特別提醒
Special reminder
1、存放在陰涼、干燥的庫房，切忌雨淋、受潮。存放時必須遠(yuǎn)離火源和熱源，避免暴曬，嚴(yán)禁與酸堿直接接觸或混放。
1.Store in a cool and dry warehouse. Avoid rain and moisture. When storing, it must be kept away from fire and heat sources, avoid direct sunlight, and strictly prohibit direct contact or mixed storage with acids and alkalis.
2、因工藝條件及環(huán)境不同，發(fā)泡情況可能有差異，故而使用前請先試一手小料。
2. Due to different process conditions and environments, the foaming situation may vary. Therefore, please test a small amount of material before use.
