Molded Bakelite forms in a condensation reaction of phenol and formaldehyde, with wood flour or asbestos fiber as a filler, under high pressure and heat in a time frame of a few minutes of curing. The result is a hard plastic material. [27] Asbestos was gradually abandoned as filler because many countries banned the production of asbestos.
Recycled plastic composite lumber observation deck at the Rachel Carson National Wildlife Refuge. Plastic lumber is a plastic form of lumber made of virgin or recycled plastic. It is mostly made of plastic and binders such as fiberglass or rebar; not to be confused with wood-plastic composite lumber. [1]
Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
Plastic consumption differs among countries and communities, with some form of plastic having made its way into most people's lives. North America (i.e. the North American Free Trade Agreement or NAFTA region) accounts for 21% of global plastic consumption, closely followed by China (20%) and Western Europe (18%).
Most composites also come with a warranty ranging from several years to the lifetime of the deck. The warranties cover the fade resistance, structural integrity and stain resistance. Many composites are often made partially out of recycled plastics and waste wood, which makes them an environmentally friendly, efficient use of resources. [2]
The process started with paper made from cotton rags. Before the processing of wood pulp and chemical wood pulps in the mid-19th century, the dominant fibre source for paper making was cotton and linen rags. The cotton rag sheet produced for conversion to vulcanized fibre is made like a sheet suitable for saturating.
Formica is a laminated composite material invented at the Westinghouse Electric Corporation in the United States in 1912. Originally used to replace mica in electrical applications, it has since been manufactured for multiple applications.
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants.It is an organic material – a natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression.
