The Basics: Polymer Definition and Properties

The Basics: Polymer Definition and Properties. Spider silk, hair, and horn are protein polymers. Starch can be a polymer as is cellulose in wood. Rubber tree latex and cellulose have been used as material to make manufactured polymeric rubber and plastics. The first synthetic manufactured plastic was Bakelite,

Chapter 6. Mechanical Properties of Metals

Tensile Properties. The stress at the yield point is called yield stress, and is an important measure of the mechanical properties of materials. In practice, the yield stress is chosen as that causing a permanent strain of 0.002 strain offset, Fig. 6.9. The yield stress measures the resistance to plastic deformation.

How to choose the right plastic for your project PlasticsToday

Lets delve into the different plastic materials to consider depending on the final part or products function. Mechanical parts. One of the most common resins used to make mechanical parts is nylon, aka polyamide PA . When PA is mixed with molybdenum it has a slippery surface for easy motion.

Mechanical Properties of Materials MechaniCalc

Mechanical Properties of Materials Stress and Strain. The relationship between stress and strain in a material is determined by Hooke's Law. Below the proportionality limit of the stress-strain curve, Poisson's Ratio. As load is applied to a material, the material elongates and Strain

Polypropylene - Wikipedia

Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material, and has a high chemical resistance. Polypropylene is the second-most widely produced commodity plastic after polyethylene and is often used in packaging and labeling.
