PP Sheets Manufacturer Delhi, India

PP Sheets have wide range of applications

PP sheets are also known as sheets of polypropene. These sheets are made from thermoplastic polymers which are utilized in an extensive variety of applications including textiles like carpets, thermal under wear, ropes etc., labeling and packaging, plastic parts, stationery, various types of reusable containers, loudspeakers, laboratory equipment, polymer banknotes and automotive components. 

 

These sheets which are used commercially are isotactic or semi crystalline which have the level of crystallinity intermediate between the high density polyethylene or HDPE or low density polyethylene or LDPE. These sheets are usually flexible and tough especially when these sheets with ethylene are copolymerized. This allows these sheets to be utilized as competing with substances like ABS or as an engineering plastic. PP sheets are relatively economical and when uncolored can be designed translucent but like other plastic sheets as acrylic or polystyrene are not readily designed transparent. These sheets are colored using pigments or are often opaque. These sheets have excellent resistance to fatigue.

At a certain range the melting points of these sheets occur so by finding the highest temperature of a chart of differential scanning calorimetry, the melting point of these sheets are determined. These sheets which are perfectly isotactic have melting point of 340 degree Fahrenheit or 171 degree centigrade. These sheets which are commercially isotactic have range of melting point from 320 to 331 degree Fahrenheit or 160 to 166 degree centigrade which depends upon the factors of crystallinity and atactic materials. These sheets which are syndiotactic have melting point of 266 degree Fahrenheit or 130 degree centigrade with 30% of crystallinity.

There are three manufacturing process used to fabricate these sheets. In hydrocarbon suspension or slurry a liquid inert hydrocarbon is utilized to facilitate the transfer to the catalyst from propylene which is diluted in the reactor. This hydrocarbon removes or deactivates the catalyst, eliminates heat from the system and also helps the atactic polymer in dissolving. In bulk slurry or bulk liquid propylene is used rather than the diluents liquid inert hydrocarbon. The polymer is carried on the liquid propylene and it does not liquefy in the diluents. The polymer which is formed is withdrawn and the monomer which does not react flashes off. In gas phase, gaseous propylene is used and when with the solid catalyst it comes in contact, a fluidized bed medium is produced. 

 

These PP Sheets are used in various promotional, packaging and protective applications. These sheets are used in making heat molded and extruded plastic items. These sheets are easily available online. Persons or organizations interested in availing these can directly contact the manufacturers.
