PVC Decking
PVC decking is composed entirely of polyvinyl chloride (PVC) and contains no wood. PVC decking is a more expensive option in the alternative decking industry, but it provides significant fade and stain resistance and lower maintenance requirements compared to other products, including real teak wood. History The alternative yacht deck covering was developed by the Dunlop company, known in the automotive industry, in the second half of the 20th century. Its popularity began to rise in the early 2000s due to the relatively high price of wooden decking and the maintenance-free nature of synthetic teak. Moreover, manufacturers have developed increasingly realistic alternatives over the decades, which could be installed more quickly and cheaply, even retrofitted on a yacht deck. Production Early manufacturing processes for PVC decking faced high scrap rates, reportedly reaching up to 12%. Advances in technology and recycling have reduced this to below 2% in many factories.Still, commerc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAL Colour Standard
RAL is a color management, colour management system used in Europe that is created and administered by the German (RAL non-profit LLC), which is a subsidiary of the German . In colloquial speech, RAL refers to the RAL Classic system, mainly used for varnish and powder coating, but now plastics as well. Approved RAL products are provided with a hologram to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources. RAL colour space system RAL Classic In 1927, the German group (Imperial Committee for Delivery and Quality Assurance) invented a collection of forty colours under the name of "RAL 840". Prior to that date, manufacturers and customers had to exchange samples to describe a tint, whereas from then on they would rely on numbers. In the 1930s, the numbers were changed uniformly to four digits and the collection was renamed to "RAL 840 R" (R for revised). Around 1940, the RAL colours were chan ...

Plastics Applications
Plastics are a wide range of synthetic or semisynthetic materials composed primarily of polymers. Their defining characteristic, plasticity, allows them to be molded, extruded, or pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends in plastic demand continue, it is projected that annual global plastic production will exceed 1.3 billion tons by ...
