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
Cryogenic deflashing and deburring is a process that employs cryogenic temperatures to remove flash on manufactured workpieces made of a wide range of plastics (and other materials) both thermoset and thermoplastic. Some examples of materials used include nylon, Tefzel®, HD-PE, PPS, PET, polycarbonate, polypropylene, polyurethane, liquid crystal polymer, ABS, PEEK, and Acetal. Manufactured parts that have been successfully deburred include those made through injection molding, compression molding and extrusion molding. … Read more
Plastic products are changing multiple facets of people’s lives, including safety in the workplace. From enhanced construction products and athletic equipment to safer auto parts and tabletops in hospitals, plastics are making a substantive change in workplace safety. Innovations in these arenas and others are expanding the applications of plastics and their contribution to sustainability.
According to The Plastic Industry Trade Association, … Read more
It is widely believed that plastics do not biodegrade, but this is in fact not the case. The concept of biodegradable plastics and polymers was first introduced in the 1980s. Bacteria that could break down plastic were developed as early as 1975, when team of Japanese scientists discovered a strain of Flavobacterium living in pools containing waste water from a nylon factory. At that time, two strains of bacteria were developed to breakdown nylon. … Read more
