Poly methyl methacrylate (PMMA)-ethylene vinyl acetate (EVA)-organoclay nanocomposites were prepared with and without in situ crosslinking using tetrapropoxysilane (TPOS) as a crosslinking agent and dibutyl tin oxide (DBTO) as a catalyst. Brabender Plasticorder experimental results suggest that in ...
gradesallow 92% of light to pass throughit, which is more than glass or other plastics. These plastic materials can easily be thermoformed without any loss in optical clarity. As compared to polystyrene and polyethylene, PMMA is recommended formost outdoor applicationsthanks to its environmental ...
Elongation at Break is the ratio of the initial and final lengths of the plastic material before it breaks. This process takes place at a controlled temperature. It is the ability of plastic material to resist changes in shape without cracking. It is also known as fracture strain or tensile...

Plastics offer advantages such as lightness, resilience, resistance to corrosion, colour fastness, transparency, ease of processing, etc., and although they have their limitations, their exploitation is limited only by the ingenuity of the designer. The term plastic refers to a family of materials ...

Poly(methyl methacrylate) (PMMA) and montmorillonite (MMT) were used as modifiers for diglycidyl ether of bisphenol A epoxy (DGEBA). The impact strength (IS), critical stress intensity factor (KC), flexural strength, and strain at break were measured as a function of modifiers content. ...
This makes it suitable over glass, PMMA, and PE. The key properties of polycarbonates include: Mechanical properties Toughness –Polycarbonate maintains a toughness value between -20°C to 140°C. They are virtually unbreakable. High Impact Strength –PC has a high strength that makes it ...
