Vinyl Polymer Production
For aficionados that are curious about the process of how vinyl records are made follow along as we go through the steps with help from telegraph mastering bonati masterting and cascade record pressing.
Vinyl polymer production. Ethylene obtained by processing or cracking natural gas or petroleum. The price received by the original manufacturer ranges from roughly 0 50 to several dollars. Polymer science and engineering. As shown in table 3 1 man made plastics fibers and rubber accounted for u s.
Major industrial polymers chemical compounds used in the manufacture of synthetic industrial materials. Although the primary. Production of about 71 billion pounds in 1992 chemical engineering news 1993 and production has tripled over the last 20 years. The other half of the vinyl polymer is based on the natural element chlorine.
Vinyl chloride was first produced in 1835 but did not go into regular production until the early twentieth century. Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. In the commercial production of plastics elastomers man made fibres adhesives and surface coatings a tremendous variety of polymers are used. Polymer production is one of the most important areas of applied chemistry due to its significant economic and social impact.
Pvc comes in two basic forms. However the main difference lies in what type of plastic they are. Vinyl polymers are the most common type of plastic. Their backbone is an extended alkane chain ch 2 chr ch 2 chr.
Vinyl siding is made of polyvinyl chloride aka pvc. At their core both vinyl and polymer are both plastics. The vinyl polymer is unusual however because it is based only in part on hydrocarbon feedstocks. In the two decades since the first edition of comprehensive polymer science impressive advances have been made regarding new methods for the synthesis of polymers from vinyl monomers.
Avid vinyl record collectors know the production process is also an extremely important one with the quality of the record on the line. They range from commodity materials such as polyethylene or pvc poly vinyl chloride up to highly specialized and expensive materials for drug. Polymers as materials are present in almost every field of human activity. In popular usage vinyl refers only to polyvinyl chloride pvc.
Vinyl polymers continue to be the most important class of polymeric materials as measured by annual production volume as well as economics. Rigid sometimes abbreviated as rpvc and flexible. Meanwhile polymer siding is made from polypropylene resin. Vinyl chloride has been used in the past as an anaesthetic and as an aerosol spray propellant but its principle use has been to produce the polymer polyvinyl chloride pvc or vinyl.
