Titanium dioxide was discovered in 1971 by a priest and mineralogist. William Gregor produced a white metal oxide by calcination black magnetic sands from Menachan, Cornwall, England. TiO2 occurs naturally mainly as anatase, rutile, and rarely as brookite. Usually, natural…

Structure and chemical properties Polycarbonates are amorphous and linear thermoplastic polyesters obtained from the reaction of carbonic acid with aromatic diols. There is little information on aliphatic, cycloaliphatic and aliphatic aromatic polycarbonates, while aromatic polycarbonates especially those made from bisphenol…

Polyolefin elastomers have the properties of thermoset rubbers, but they can be processed using standard equipment for processing thermoplastic polymers. Products made based on POE provide a specific range of physical-mechanical properties in such a way that they adequately fill…

Polypropylene (PP) was introduced to the market in the late 1950s and is the most widely used economic-commercial thermoplastic that has grown and developed the fastest in the world. PP is a polymer with multiple and diverse applications that has…

Chemical structure and general properties of acrylic are as follow: PMMA Properties Acrylics are composed of polymers and copolymers whose main monomers belong to the two families of ester-acrylates and methacrylates. Transparent and hard acrylic sheets are made from methyl…

Introduction Polyamides are high molecular weight polymers that have an amide group in their main chain which is considered as the main component of the polymer chain. The amide groups strongly adhere to each other and ensure high strength. These…

Product Introduction Fiber reinforcements Composites usually consist of a matrix to hold the reinforcing materials. Reinforcing materials are the most important factors to grant strength to a composite system and have different shapes. These materials are able to conduct heat…
