Bakelite ( / ˈbeɪkəlaɪt / BAY-kə-lyte ), formally polyoxybenzylmethyleneglycolanhydride, is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on ...
Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together. [ 1] Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing ...
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. High-density polyethylene bottles introduced and soon replace glass bottles in most applications.
Extruded aluminium with several hollow cavities; T slots allow bars to be joined with special connectors. Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very ...
HDPE has SPI resin ID code 2. High-density polyethylene ( HDPE) or polyethylene high-density ( PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. [ 1] With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion ...
Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
Pipe is usually delivered to a customer or jobsite as either "sticks" or lengths of pipe (typically 20 feet (6.1 m), called single random length) or they are prefabricated with elbows, tees and valves into a prefabricated pipe spool [A pipe spool is a piece of pre-assembled pipe and fittings, usually prepared in a shop so that installation on ...
