Don’t expect more than you inspect! When properly installed, fire sprinkler systems not only make a commercial or residential building safer for its occupants, but also ensures building owners and construction companies remain in compliance with regulations set by the industry or government.
Are Polypropylene Mesh Implants Safe?
Recent problems and failures with PP mesh implants have led to thousands of hernia and surgical mesh lawsuits All products that contain hydrogen bonded to carbon are susceptible to oxidative degradation. For example, foods that we eat and medicines that we take contain hydrogen bonded to carbon.
The Impact of Plastics on the Environment
Plastics have been around for about 80 years. In that time, they have greatly impacted our lives and provided significant benefits including convenience, health and safety. Weight-saving advantages of plastics over metal have greatly improved fuel efficiency of automobiles, thereby reducing our
Redesign of Plastic Pail to Eliminate Failure
Dr. Duane Priddy, Plastic Expert Group Plastic five-gallon pails, with handles attached, are used extensively. Our client manufactures these pails and was experiencing occasional failure at the point of attachment of the handle to the side of the pail. Our experts evaluated the current design and
Redesign of Plastic Bottle Closure to Eliminate Failure
Dr. Duane Priddy, Plastic Expert Group The client manufactures plastic bottles for chemical solutions. At the end of the threads is a tab that produces a clicking sound when the screw cap was fully seated. Occasionally a tab would break off the bottle. Our experts evaluated the current design and
Cause of Worm-Tracking of Chrome Plated ABS Bumpers
Dr. Duane Priddy, Plastic Expert Group The client manufactures chrome-plated ABS bumpers for an automotive customer. They periodically experience bumpers with “worm tracking” on them as seen in the figure below. Our experts extensively analyzed a worm-tracked bumper comparing areas where the
Fiber Optic Not Resistant to Corrosive Chemicals
The product shown below is an inspection light using the principles of illumination fiber optics to disperse high-intensity light in a 360-degree pattern and is widely deployed by military and homeland security personnel. The light enters the fiber optic from a 5-Watt LED flashLight (circled area).
Improved Fiber Optic Materials by Improving the Polymerization Process
Acrylic and methacrylic-based optical systems generally exhibit superior optical properties such as light transmission when bulk polymerized (e.g., cast in situ) in the purest form possible. There are normally two types of impurities that cause bulk scattering, bubbles, and chemical impurities such
