Thermal Expansion Of Acrylic Sheet

Plexiglas acrylic sheet will expand and contract with changes in temperature and humidity.

Thermal expansion of acrylic sheet.

Abs pipes pressure ratings pressure ratings of. Acrylic sheet is subject to greater dimensional change due to thermal expansion and contraction than other materials with which it is used in construction. Coefficient of thermal expansion. Thermal properties of plastic materials material formula coefficient of thermal expansion x10 6 k 1 heat deflection temperature 0 45mpa c heat deflection temperature 1 8mpa c lower working temperature c specific heat j k 1 kg 1 thermal conductivity w m 1 k 1 upper.

Available in extruded and or cast material in sheet rod and tube forms as well as custom profiles. However this type of bowing is reversible. Thermodynamics effects of work heat and energy on systems. Perspex cell cast acrylic technical data sheet 1.

Astm d696 this test method covers determination of the coefficient of linear thermal expansion for plastic materials having coefficients of expansion greater than 1 µm m c by use of a vitreous silica dilatometer. Material properties material properties for gases fluids and solids densities specific heats viscosities and more. Cast versus extruded acrylic. Thermal expansion can present significant challenges for designers in certain areas for example when constructing spacecraft aircraft buildings or bridges but it can have positive uses.

Masking perspex sheet is supplied with double sided non thermoformable masking. For example the expansion joints in cement sidewalks and on steel bridges. Range perspex cell cast acrylic sheet is available in clear opal and many colours in a range of thicknesses sizes and special grades. The use of acrylic.

Different temperature and or humidity conditions on the inner and outer surfaces of plexiglas sheet may cause it to bow slightly in the direction of the higher temperature and or humidity.
