The plastic card hardness equivalent to steel several times

pc embossed sheet

Specially appointed professor of composition of a country polymer physics research group, announced that it has developed a plastic sheet hardness equivalent to steel five times. Such a plastic sheet for a few tenths of a millimeter thick, transparent, and plasticity, and is expected to be used as alternatives of the car body and glass. The difference between the upper and lower its cost with ordinary plastic. Free of impurities, easily recycled, it is expected as a new material to popularity. Expected to first discuss the practical use in the field of food containers. The scientific team in less than a melting point of approximately 150 ° C to a strip of the liquid polymer polypropylene instantaneously compressed, then the belt portion of the molecule is stretched and arranged neatly together, the crystals become tightly and securely. The tensile strength of 230 MPa, is more than seven times the past polypropylene. According to reports, this strength is equivalent to five times the same weight of steel. The research team estimates that the alternative in this material body of steel, the cost can be reduced to one-third to one-fourth.
