PA PET PU TPU PC PBT PMMA CA Plastic Dehumidifier Dryer

In the plastic processing industry, shrinkage, silver streaks, bubbles, cracks, flow marks, poor transparency and other phenomena will appear in the product. The main reason for these poor qualities is that the plastic was not sufficiently dried before molding. Engineering plastics such as: PA, PET, PU, ​​TPU, PC, PBT, CA and other materials with strong hygroscopicity, because the moisture penetrates into the plastic particles, the traditional hot air dryer cannot completely dry them. Practice has proved that reducing the dew point of the dry air to below -40°C while controlling the heat to blow over the surface of wet plastic particles can reduce the moisture content before molding to below 0.02%. The three-in-one dehumidification dryer is airtight . The air is fully dehumidified and heated in the circulation system, and the dry air quickly and completely separates the moisture in the plastic particles to achieve the effect of dehumidification and drying.
