TORLON® Polyamide-imide

TORLON® Polyamide-imide
TORLON® polyamide-imide  is a Solvay brand name for polyamide-imide or PAI. Polyamide-imides demonstrate exceptional mechanical, thermal and chemical resistance properties making them well suited to severe environmental service. PAIs have exceptionally high heat performance with a continuous service temperature of 260°C or 500°F and are inherently flame resistant. They are known to have the highest strength and stiffness at higher temperatures of any thermoplastic. Torlon® resists wear, creep and is also extremely durable from cryogenic temperatures to 275°C (535°F). … Read more

The Development of Modern Plastics

During the late 19th century natural resources such as wood, ivory, and tortoiseshell were being depleted at a rapid rate. Ivory and tortoiseshell were highly sought-after materials for luxury items including hand-carved combs, hand-held mirrors, jewelry boxes, and many high-end personal items enjoyed by the well-to-do at the time. These materials were also used extensively for medical and dental instruments and more utilitarian uses such as pistol grips.
With the immense technological progress in chemistry and a need to find a replacement for dwindling natural resources, … Read more

ISO9001:2015 Upgrade

Just when you thought you had the ISO 9001:2008 quality system down, low and behold you find out that a new standard has been issued by ISO. ISO 9001:2015 was released in September 2015, as the 5th edition of one of ISO’s most widely accepted standards.  All ISO standards are reviewed every five years to determine if they meet the needs of industries and users based on the latest trends globally.  Some of you have been busy transitioning or have already done so to meet the deadline of September 2018. … Read more

Hudson, New York: A Brief History

Hudson, NY is a small city with a rich history and a magnificent location on the east shore of the Hudson River 120 miles north of New York Harbor.
It was originally inhabited by the Mohican Indians. The first known European to navigate the river was Henry Hudson in 1609. Originally called Claverack Landing, there were 10 farming families and fewer than 150 residents. While it was a successful center, it seemed an unlikely place for a whaling port. … Read more

Creep in Plastic Materials

What is Creep in Plastic Materials?
Creep in plastic materials is sometimes referred to as cold flow.
Viscosity
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear or tensile stress.  Viscoelastic behavior is the property of a material to display both viscous and elastic characteristics when undergoing deformation.  The difference between plastics and other materials is that plastics display time-dependent viscoelastic behavior.  A material can deform as the result of long-term exposure to high levels of stress that are still beneath the yield strength or yield point of the material. … Read more
