Polymers are organic macromolecules, a long carbonic chain, composed by structural repeat entities, called mer. These smallest unit, for instance, are bonded by covalent bonds, repeating successively along a chain. A monomer, molecule composed by one mer, is the raw material to produce a polymer.

This PSU snap rivet is fast to install, with specially designed legs that expand and firmly lock the component parts permanently in place. They fit with a simple push for a smooth finish. Ideal for panel fastening and server rack applications. WebbThis property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products.
The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. There is in fact a hierarchy of structures, in which each stage provides the foundations for the next one. The starting point for the description of the structure of a polymer is the identity of its constituent monomers. Next, the microstructure essentially de… Webb20 juni 2024 · It is useful at temperatures up to nearly 500 degrees Fahrenheit and self-extinguishes in heat and fire, making it highly recommended for use in electrical components with high continuous service temperatures, e.g. in aerospace.
