Recycled Polythene or recycled Polypropylene often contain trace moisture, if not eliminated, the moisture will form into drain marks or bubbles on the surface of the related products when processing.
CaO Moisture Absorber for Recycled Polythene,also named Desiccant Masterbatch,Recycled Plastic Raw Material Dryer, Recycling PE Dryer,which as a kind of Plastic Additive, with below features:
1. This product will be directly mixed with the plastic raw materials uniformly, which will be used to carry out processing without baking the raw materials;
2. Adding amount is within 1% - 5%, 3% is the generally recommended dosage, which is adjustable according to moisture content of the raw materials.
3. Since the it have a good plasticizing performance and mobile performance, processing temperature can be reduced by 5 % -10 %.
4. The following three steps will be passed when processing: [batching] - [pre-mixing] - [forming]
5. Batching: in accordance with the requirements of plastic parts, choose the batching ratio.
6. Pre-mixing: adding the weighed materials and suitable amount of colorants or master-batch into the mixer, to carry out the simple pre-mixing.
7. Forming: loading the well pre-mixed materials into the plastic jetting-molding machine or the hopper of the extruder, execute
