As we all know, PC is commonly known as polycarbonate and has very good mechanical properties, so it is commonly known as bulletproof glue. PC has the characteristics of high mechanical strength, wide operating temperature range, good electrical insulation performance, good dimensional stability, and transparency. Can be used in many occasions. For example, it is widely used in electrical products, electrical instrument housings, and electronic product structural parts. On the other hand, there are many modified PC products, usually adding glass fiber, mineral fillers, chemical flame retardants, and other plastics. Another point is that PC has poor fluidity and high processing temperature, so the processing of modified materials requires a special plasticized injection structure. This is one of the characteristics of the PC.

Normally, the water absorption rate of plastic is relatively high. It must be preheated and dried before processing, and pure PC must be dried at 120°C, and the drying time must be accurate. Modified PC is generally dried at 110°C for more than 4 hours. However, the drying time cannot exceed 10 hours. It can also be viewed by other methods. Generally, the air extrusion method can be used to judge whether the drying is sufficient. The use ratio of recycled materials can reach 20%. In some specific cases, 100% recycled materials can be used, and the actual amount depends on the quality requirements of the product. Recycled materials cannot be mixed with different masterbatches at the same time, otherwise it will seriously damage the properties of the finished product. Pay more attention to this point.
