Consider An Acrylic Sheet Of Thickness

It is a tradename of lucite international and is polymethyl methacrylate pmma acrylic sheet which is manufactured from methyl methacrylate monomer mma.

Consider an acrylic sheet of thickness.

Consider an acrylic sheet of thickness l 5 mm that is used to coat a hot isothermal metal substrate at th 300 degree c. These are general guidelines for thickness tolerances on plexiglass acrylic sheets. As an example if the sheet is up to 1 5 sq. Plexiglas g acrylic sheet in thicknesses 0 118 0 236 and 0 472 pass the requirements for flammability per faa far 25 853 appendix f part 1 paragraphs a 1 iv procedure b 5 15 second horizontal test formaly 25 853 b 2.

Metres 3mm should suffice while anything between 1 5 and 2 sq. A 125 thickness of acrylic is 2 to 3 times more impact resistant than double strength window glass 4 to 5 times more impact resistant than wire glass or other glasses. A 250 thickness of acrylic is 9 to 10 times more impact resistant than wire or other glasses. While acrylic is robust it still needs supporting when used in large sheets so opt for a thicker sheet when in doubt if the dimensions are on the larger side.

How does acrylic compare to other plastics in strength. Exact thickness tolerances will vary by manufacturer. Please call us at 858 560 1551 with any questions. Metres should have a minimum thickness of 4mm.

We strongly recommend that you always opt for cast acrylic. 201 th 5 38 consider an acrylic sheet of thickness l 4 mm that is used to coat a hot isothermal metal substrate at. Perspex is a brand name for acrylic. For windshields with a sheet width of 1 metre we recommend a sheet thickness of 8 millimetres and for every 50 centimetres that the sheet is wider the sheet must be 1 millimetre thicker.

The properties of the acrylic are rho 1990 kg m3 c 1470j kg middot k and k 0 21 w m middot k. Neglecting the thermal contact resistance between the acrylic and the metal substrate determine how long it will take for the insulated back side of the acrylic to reach its softening temperature tsoft 90 degree c.
