Polypropylene is first choice for this application. Polypropylene is one of the most significant polymer of modern times. It has low specific gravity comparing to many other plastics and has strong mechanical properties. It can be processed in various ways without big loss to its mechanical and chemical properties.
Polypropylene doesn’t react with diluted acids, bases. It is elastic but tough. It can be reformed without breaking. It retains the shape after a lot of torsion, bending or flexing. This is highly resistant to electricity. In the natural form, it is almost transparent. Polypropylene has a melting point of around 130 to 160 Deg. C. which is much higher than the temperatures often found in the natural conditions. It can be made UV resistant easily with the help of additives.
Polypropylene can be melt at 160 Deg C and can be profiled as per the requirement. Polypropylene is extruded on the T Die Cast Extruders. After annealing, process of re- orientation of molecules starts by cold and hot roll stretching, hot air bath, high degree of stretching, etc. The film is mechanically fibrillated in a way to ensure mechanical properties are not lost. The stretched and stable fiber obtained is cut into required specific lengths. This is chemically treated to remove static force and is packed online in plastic bags so as to ensure no moisture or contamination exists.
