How to Identify a Plastic Material Using the Burn Test

So you have a plastic part and you need to know what it is made of but you have no idea what plastic it is. This can be a challenging task. Many plastics look and feel alike but we will take a closer look here at some of the ways using a burn test. Please note, this test should be done in an industrial setting and not at home since proper safety protocol must be observed. … Read more

A Technical Look at Polymer Synthesis and Additives

Originally, plastic resins were made from vegetable matter including cellulose from cotton, furfural from oat hulls, oils from seeds and various starch derivatives. Bakelite (phenol formaldehyde resin), one of the first plastics made from synthetic components, was developed by Belgian born chemist Leo Backeland in New York in 1907. Bakelite is made through an elimination reaction of phenol with formaldehyde. It was originally lused for its electrical non-conductivity and heat-resistant properties in electrical insulators, … Read more

How Is Nylon Made?

For centuries, inventors tried to create a “synthetic silk.” In the early 1880’s, Sir Joseph Swan
experimented with forming threads by dissolving the inner bark of mulberry trees. Although Swan did realize that fabric could be woven from this material, he never pursued this application as he was mainly interested in finding a filament for Thomas Edison’s light bulbs. It was not until 1889 that the French chemist Count Hilaire de Chardonnet developed rayon or “artificial silk,” which he introduced at the Paris Exhibition. … Read more

5 Common Tamper-Resistant Screw Drives

Screw drives that require special tools to torque into place or to unfasten are considered to be tamper resistant. They also tend to be fairly rarely used. These drives are ideal for applications ranging from aerospace technology to video game consoles, because they inhibit tampering or unsupervised repairs. Each of the five drives listed below are considered tamper resistant, but not tamper proof, given the availability of screw driver bits on the market.  For a tamper proof screw installation, … Read more

Design Benefits of Thermoplastics in Pump and Valve Components

Thermoplastic components strengthen pumps and valves through resistance to corrosion, lower repair costs and extended service lives, which is why operators are choosing plastics over metal parts. There are many more advantages to using plastics, including decreased vibration and higher temperature thresholds that enhance operational efficiency. Ultimately, all of the thermoplastic design benefits equate to cost-savings and greater reliability in the field.

Temperature Resistance
Thermoplastics have less thermal conductivity compared to metal components, which is beneficial for preventing damage to pumps and valves exposed to high internal and external temperatures. … Read more
