Top 7 Reasons Manufacturers Love Polycarbonate

First commercially manufactured in the late 1950’s, polycarbonate is a high-strength plastic with many industrial applications due to its special properties.  The material has good electrical insulation properties and is heat-resistant.  Polycarbonate is so ubiquitous in part because it can be manufactured as clear as glass.  The plastic is stronger than glass and has only 1/6 the weight of glass-making it the preferred choice for many manufacturers. 
Due to its strength and light weight,Read more

A Closer Look at Glass Fibers in Reinforced Plastic

As we discussed in our last post, reinforcing fibers are added to plastic resins to increase the tensile strength and flexural modulus of the composite as well as the heat deflection temperature of the plastic.  In this blog post, we will take a closer look at glass fibers.
Glass fibers are used as a reinforcing agent for many plastic composites.  Called GRP’s or glass reinforced plastics, these materials are made up of many fine fibers of glass combined with a plastic matrix.Read more

A Special Highlight on Basalt and Aramid Fiber Reinforced Plastic

Fiber reinforced plastic is a mixture of reinforcing fillers and plastic resins called matrixes.  This technique increases the tensile strength and flexural modulus of the composite.  These fillers also increase the heat deflection temperature of a material as well as cause it to resist shrinkage and warping. The extent to which these attributes are enhanced depends on the mechanical properties of the fiber and the matrix, their volume relative to each other and the length and orientation of the fiber within the matrix. Read more

How Do Scientists Define Clear Plastic?

So I wanted to do an article for our readers on the most optically clear plastics available.  But then I got so caught up in researching what “transparency” really means that I decided this topic really deserves two articles. 
Here’s a rundown of two of the major ways of measuring transparency in plastics (and other materials)-the refractive index and optical clarity.  Keep your eye out for a second post listing highly transparent plastics in the next few weeks.Read more

An Introduction to Anti-Static, Dissipative, and Conductive Plastics

Wait!  Aren’t all plastics conductive?  Aren’t plastics the ultimate insulators?  You’re right-plastics are used extensively in many industries, including electronics, as insulators.  But plastics are not just naturally dissipative; most of them are made that way using additives.  Let’s examine how anti-static, conductive, and dissipative plastics are produced and classified.
In order to understand how this works, let’s take a second to examine the phenomenon of electrostatic charge and conductivity.  An electrostatic charge is one that occurs when two objects touch each another.Read more
