Additional Physical Format: Online version: Lever, Arnold Eric. Properties and testing of plastics materials. New York, Chemical Pub. (OCoLC) Plastics are part of everyday life and contribute immensely to the benefit of humanity.

When failures occur, they are due in part either to inferior properties (resulting from poor design or badly controlled processing), or to an incomplete understanding of the properties and applications of plastics materials.

Material Properties of Plastics Formation and Structure The basic structure of plastics (or polymers) is given by macromolecule chains, formulated from monomer units by chemical reactions.

Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure ). In this chapter plastics have been generally dealt with in respect to broad categories of properties, namely, mechanical, electrical, thermal, and optical.

In this treatment the most characteristic features of plastic materials have been highlighted. An important facet of materials development and proper materials selection is testing and standard.

properties and testing of plastics materials book Tensile properties are among the most important mechanical properties of plastics. Tear Strength is considered as the "tear resistance", which is the force required to start tearing flexible plastic films. Vibration tests can be grouped into two categories: repetitive-shock vibration tests Author: Laszlo Horvath, Byungjin Min, Young T.
