Plastics Its All About Molecular Structure

This means that the properties of a plastic material, such as strength and ductility, are not static, but will decrease over time. This often leads to creep and stress relaxation within plastic materials. Crystalline/Amorphous Structure. Another fundamental characteristic of polymeric materials is the organization of their molecular structure.

Plastics by the Numbers

#1 - PET (Polyethylene Terephthalate) PET is one of the most commonly used plastics in consumer products, and is found in most water and pop bottles, and some packaging.It is intended for single use applications; repeated use increases the risk of leaching and bacterial growth. Plastics with good mechanical properties EnsingerFor example, tensile properties of plastics such as plastic tensile strength and rigidity can be determined according to DIN EN ISO 527 by briefly applying load in one direction with a tensile test. The possible results and typical values observed during such test, depending on material behaviour, are summarised in the following graph: Plastics with good mechanical properties EnsingerStrength - Tensile and flexural (mechanical resistance) Flexural strength and tensile strength of plastic are two of the most commonly used values to compare materials.

Plastics:Types, Properties, Composition and Structure

Plastic refers to its ability to deform without breaking. The polymer used in making a plastics are usually a combination of additives, colorants, plasticizers, stabilizers, fillers, and reinforcements. These additives affect the chemical composition, properties, and mechanical properties of plastics and affect its cost.
