PC raw material application and its advantages and disadvantages

Many of the things we come into contact with in daily life involve the PC. Our hair straighteners and curling stick products are also used more. The following is the corresponding knowledge of some PC plastics.

In our products, many machines use PC raw materials, which is called polycarbonate in Chinese. PC is a new type of thermoplastic with a transparency of up to 90%. It can be said that it is a transparent metal in plastic and has rigidity. Toughness, strong impact, high dimensional stability and a wide range of use temperature, good electrical insulation performance and heat resistance, non-toxic, can be injection molded by extrusion. PC has excellent thermal performance and can be used for a long time between -100℃-130℃, -100℃ belongs to the embrittlement temperature. Although the PC material has poor resistance to cracking boxes, it is easy to dissolve water at high temperatures, has poor compatibility with other resins, and has poor lubricating properties. It needs to be improved by adding other resins or inorganic fillers to obtain very excellent performance.

PC raw material application range: used to manufacture large lampshades, protective glasses, eyepiece tubes for optical instruments, and can also be widely used in aircraft transparent materials and LED and other optical lighting.

Excellent E (120℃) grade insulation materials, used to make insulation connectors, coil frames, tube sockets, insulation sleeves, telephone casings, hair straighteners, curling irons, hair dryers and other hairdressing tools, as well as high dimensional accuracy of zero Accessories, such as compact discs, electronic computers, video recorders and other electronic appliances for communications equipment. In the field of mechanical equipment, it is used to manufacture various gears, racks, bearings, levers, etc., and can also be used in mechanical equipment shells, cover box frames and other parts. There are also daily necessities such as medical equipment, food tableware, and baby bottles.

Summary of advantages of PC material (polycarbonate):

1. High strength and elasticity coefficient, high impact strength, wide operating temperature range;

2. Very high transparency, can dye the desired color;

3. High heat resistance, high H.D.T.

4. Tasteless and odorless, harmless to human body, in line with health and safety, food grade;

5. Low molding shrinkage rate, good qualitative size, easy to process;

6. Excellent electrical characteristics. High flame retardant level;

7. UV resistance, good weather resistance, excellent fatigue resistance and strong toughness.

Summary of shortcomings of PC material (polycarbonate):

1. Poorly designed molded products are prone to internal stress problems;

2. The requirements for the injection molding machine are extremely high during processing, and the processing temperature is about 310°.
