Several types of polymeric foams are used for cushioning, the most common being expanded polystyrene, polypropylene, polyethylene, and polyurethane. These can be molded engineered shapes or sheets which are cut and glued into cushion structures. [5] Convoluted (or finger) foams are sometimes used. [6] Some degradable foams are also available. [7]
Polypropylene was discovered by Giulio Natta with production starting in 1957 [1] 1954: Expanded polystyrene, used for building insulation, packaging, and cup, was invented by Dow Chemical. [1] 1957: Italian firm Montecatini begin large-scale commercial production of isotactic polypropylene. 1960s
In 1954 polypropylene was discovered by Giulio Natta and began to be manufactured in 1957. [4] Also in 1954 expanded polystyrene (used for building insulation, packaging, and cups) was invented by Dow Chemical. [4]
Airframes are constructed of any material, with wood, fiberglass and/or carbon fiber being preferred for gliders intended for precision aerobatics, and EPP (expanded polypropylene) being popular for low altitude aerobatics where interactions with the ground - like wingtip and/or inverted fin drags, or touch-and-goes off of obstacles - are ...
