Poly(methyl methacrylate) (PMMA)

CAE DS Injection Moulding Materials Poly(methyl methacrylate) ( pmma ). Technical University of Gabrovo Milena Koleva General Poly(methacrylates) are polymers of the esters of methacrylic acids. The General most commonly used among them is Poly(methyl methacrylate) ( pmma ). Poly(methyl methacrylate) or poly (methyl 2 methylpropenoate) is the polymer of methyl methacrylate, with chemical formula C5H8O2)n. It is a clear, colourless poly . mer available on the market in both pellet and sheet form under the names Plexiglas, Acrylite, Perspex, Plazcryl, Acrylplast, Altuglas, Lucite etc.

Tensile Creep Modulus, 1 h 1800 ‐ 2700 MPa Tensile Creep Modulus, 1000 h 1200 ‐ 1800 MPa The low water absorption capacity of PMMA makes it very suitable for electrical engineering purposes. Its dielectric properties are very good, but polystyrene and LDPE are superior to it.

Melt Flow Index - Plastics World

Carbon blacks have the most pronounced effect, and unless very high flow polymers are used as carriers, resultant masterbatches have little or no flow when measured using a standard 2.16 kg weight. For this reason most data sheets quote values measured using higher weights (e.g. 21.6 kg). For example, a typical masterbatch

• Mechanical properties of polymers change dramatically with temperature, going from glass-like brittle behavior at low temperatures to a rubber-like behavior at high temperatures. • Polymers are also very sensitive to the rate of deformation (strain rate). Decreasing rate of deformation has the same effect as increasing temperature (T).
