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

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
The Development of Polyester.
Polyester was developed in the years 1939-1941 by British chemists at Calico Printers Association, Ltd., based on the work of W.H. Carothers in 1926 at the United States based E.I.D. Pont de Nemours and Co. DuPont bought the rights in 1946 to produce polyester fiber in the United States. By 1951, DuPont had begun to market the fiber under the name Dacron.
What Polyester is Made of.
Polyester is made up of long-chain polymers. … Read more
The most widely used thermoplastic material in the medical device industry is PVC. Over a 50 year period, this material has demonstraced its ability to met the demanding requirements of the healthcare industry. PVC was originally developed to replace the rubber and glass that was historically used to make flexible tubing and containers. PVC began to dominate the market for these types of items when the need for single use pre-sterilised medical components increased. … Read more
