Their thermoplastic nature allows TPVs, unlike traditional vulcanized rubbers, to be melted and reprocessed multiple times. Across the automotive, household appliance, electrical, construction, and healthcare sectors, nearly 100 TPV grades are used globally. Monsanto trademarked the name Santoprene for these materials in 1977. [1]
Zytel is a trademark owned by Celanese and used to make different high-strength, abrasion, and impact-resistant thermoplastic polyamide formulations, in the family of material more commonly known as nylon.
Vectran is a manufactured fiber, spun from a liquid-crystal polymer (LCP) created by Celanese Corporation and now manufactured by Kuraray. Chemically it is an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid.
Celanese Corporation, formerly known as Hoechst Celanese, is an American technology and specialty materials company headquartered in Irving, Texas. [3] It is a Fortune 500 corporation. The company is the world's leading producer of acetic acid , producing about 1.95 million tonnes per year, representing approximately 25% of global production. [ 4 ]
An ABS 3D bell manufactured with a 3D printer. Engineering plastics [1] are a group of plastic materials that have better mechanical or thermal properties than the more widely used commodity plastics (such as polystyrene, polyvinyl chloride, polypropylene and polyethylene).
In manufacturing processes by polycondensation a high purity of the starting materials is important. In addition, the stereochemistry plays a role in achieving the desired properties in general. The development of new high-performance plastics is therefore closely linked to the development and economic production of the constituent monomers. [2]
The process can use thermosetting, thermoplastic prepregs (pre-impregnated composite fibers), and wet resin with dry fiber to produce superior composite parts. This out of autoclave process can achieve aerospace grade void contents of less than 2%, with extremely fast cycle times, and at significantly lower pressures and lower labor costs than ...
Polylactic acid (polylactide) is a compostable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), sugar beet pulp (in Europe), tapioca roots, chips or starch (mostly in Asia), or sugarcane. It is the most common material used for 3D printing with fused deposition modeling (FDM ...
