Biodegradable plastics have become more appealing in recent years as traditional consumer plastic products continue to choke landfills, negatively impacting the surrounding environment. Biodegradable plastics take between three and six months to decompose, which is a significant improvement over the hundreds of years most traditional plastics need. Biodegradable plastics are still in development and the current commercially available grades are far from perfect. Despite any drawbacks, scientists continue to develop and refine bioplastics because the potential benefits are hard to deny. … Read more
High-tech rockets, expensive propellants and billions of dollars in research aren’t the only things that have advanced space exploration. Plastic materials have played a vital role throughout the history of spaceflight, allowing astronauts to view their surroundings, breathe oxygen and travel comfortably in orbit around the earth, or on the way to the moon. Without plastics, space exploration would not be where it is today.
Stronger Helmets & Visors
When you think of the first astronauts to visit the moon, … Read more
A burr (also known as a “flash”) is an unwanted raised edge or small piece of material left after a part has been worked in a manufacturing process. It can be metal, rubber, plastic or really any other material used in manufacturing. Machining operations such as grinding, drilling, milling, turning, tapping, slotting etc. cause burrs in machining operations. As you can see in the picture on the right, burrs give plastic a messy, unfinished appearance. … Read more
Working at a plastic manufacturing company, I’m familiar with the concerns many people have about the impact of plastic materials on the environment. The vast majority of polluting plastics are single-use, consumer products like takeout containers, plastic utensils, and plastic bottles. While plastic recycling rates continue to improve in the United States (by 4.3% in 2014), some companies are already looking for new methods of creating sustainability through the development of plant-based polymers. … Read more
Polyetheretherketone (PEEK) is a high performance, semicrystalline, high temperature resistant, engineering thermoplastic. It is one of the most popular materials we manufacture here at Craftech, with a strong following in the aerospace industry. In this article, we will describe some of the excellent mechanical properties that make this plastic material so popular.
The processing conditions used to mold PEEK can influence its crystallinity and mechanical properties. The Young’s modulus is 3.6 GPa and its tensile strength is 90 to 100 Mpa. … Read more
