Stronger-than-Steel Plastic

Israeli scientists have developed a new catalyst that makes polypropylene strong enough to replace steel in a variety of applications. For example, because of its high melting point, the new material may be substituted for many traditional steel parts in cars, resulting in lighter vehicles that are more fuel efficient. At a weight ten times less than steel and one hundred times less than concrete, plastic would offer a tremendous advantage over other raw materials for many uses including pipeline construction.

Because plastic pipes can now be made stronger than steel, they can be used in applications that required steel in the past. In addition, since plastics are less prone to breakage and leaks, plastic pipes could result in more efficient water use. In addition, durable plastics are easier to produce, consuming less energy and requiring fewer raw materials.
