Polyvinyl chloride (alternatively: poly (vinyl chloride), [ 6][ 7] colloquial: vinyl[ 8] or polyvinyl; abbreviated: PVC[ 8]) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene ). About 40 million tons of PVC are produced each year.
Teslin (material) Teslin is a waterproof synthetic printing medium manufactured by PPG Industries. Teslin is a single-layer, uncoated film, and extremely strong. Its official website states that it is recyclable and non-toxic. [ 1] The strength of the lamination peel of a Teslin sheet is 2-4 times stronger than other coated synthetic and coated ...
Crazing. Crazing is a yielding mechanism in polymers characterized by the formation of a fine network of microvoids and fibrils. [ 1][ 2] These structures (known as crazes) typically appear as linear features and frequently precede brittle fracture. The fundamental difference between crazes and cracks is that crazes contain polymer fibrils (5 ...

Environmental Stress Cracking ( ESC) is one of the most common causes of unexpected brittle failure of thermoplastic (especially amorphous) polymers known at present. According to ASTM D883, stress cracking is defined as "an external or internal crack in a plastic caused by tensile stresses less than its short-term mechanical strength".
Vinyl banner. Vinyl banners are a form of banners made of vinyl. The most commonly used material is PVC (polyvinyl chloride). Most banners are now digitally printed on large format inkjet printers which are capable of printing a full color outdoor billboard on a single piece of material. They are used for outdoor advertising .
Plastic cards usually serve as identity documents, thus providing authentication. In combination with other assets that complement the data stored on the card, like PIN numbers, they also serve authorization purposes, most often as bank cards for allowing their holders to do financial transactions. Early and simpler cards feature only hard-to ...
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture . Theoretically, the stress ahead of a sharp ...
