High performance plastics are relatively expensive: The price per kilogram may be between $5 and $100 . The average value is slightly less than 15 US-Dollar/kg. [5] High-performance plastics are thus about 3 to 20 times as expensive as engineering plastics. [2]
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
Worldwide, more than 53 million tons of fillers (with a net worth of ca. US$18 billion) are used every year in the production of paper, plastics, rubber, paints, coatings, adhesives, and sealants. Fillers are produced by more than 700 companies, rank among the world's major raw materials and are contained in a variety of goods for daily ...
SPE's holds its Annual Technical Conference or ANTEC® each spring in various locations throughout North America. The meeting includes presentations of peer-reviewed technical papers about plastics innovations and technologies from around the world. ANTEC® also showcases the latest advances in industrial, national laboratory and academic work.
Polypropylene is commonly used in car bumpers, interior trims, and other components [19] where TiO₂ is added to improve the UV stability of the plastic, ensuring that parts do not degrade or lose color when exposed to sunlight over time. [20] Polyethylene films are widely used in agriculture for greenhouses, mulching, and silage wraps. [21]
General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. [6] Polystyrene is one of the most widely used plastics, with the scale of its production being several million tonnes per year. [7]
The University of Pennsylvania (Penn [note 3] or UPenn [note 4]) is a private Ivy League research university in Philadelphia, Pennsylvania, United States.It is one of nine colonial colleges and was chartered prior to the U.S. Declaration of Independence when Benjamin Franklin, the university's founder and first president, advocated for an educational institution that trained leaders in ...
A TPU resin consists of linear polymeric chains in block-structures. Such chains contain low polarity segments which are rather long (called soft segments), alternating with shorter, high polarity segments (called hard segments). Both types of segments are linked by covalent links so that they actually form block-copolymers.
