After the war, PVC was not a popular choice of materials in the marine industry due to its density. In the 1970s, the need for a strong, moisture-resistant material led to plastic manufactures working with PVC to make it lighter. This led to the creation of PVC foamboard, by combining PVC with polyurea at the molecular level. [1]
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.
a wet process similar to pulp mills in which the fibers are softened and under heat and pressure the ligin in the fibres is used to create boards. The boards are limited to approximately 25 mm thickness; thicker boards are made by gluing (with modified starch or PVA wood glue). Additives such as latex or bitumen are added to increase water ...
WPC sandwich boards consist of wood polymer composite skins and usually low-density polymer core which leads to a very effective increase of panel's rigidity. WPC sandwich boards are used mainly in automotive, transportation and building applications, but furniture applications are also being developed. [ 22 ]
Vinyl siding is plastic exterior siding for houses and small apartment buildings, used for decoration and weatherproofing, imitating wood clapboard, batten board and batten or shakes, and used instead of other materials such as aluminum or fiber cement siding. It is an engineered product, manufactured primarily from polyvinyl chloride (PVC
Plastic lumber is composed of virgin or waste plastics including HDPE, PVC, PP, ABS, PS and PLA.The powder or pellets are mixed to a dough-like consistency at roughly 400 °F (204 °C) and then extruded or molded to the desired shape.
Wall panels made from materials like gypsum board are often selected for their inherent fire-resistant properties. Other materials, such as PVC and WPC panels, can be treated with fire-retardant coatings to meet safety standards. Fire-resistant panels slow down the spread of flames and help contain fires within specific areas, thereby providing ...
Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). It typically contains no clay minerals, but like mineral clay a liquid is added to dry particles until it achieves gel-like working properties. Similarly, the part is put into an oven to harden, hence its colloquial designation as clay. [1]
