Acrylic Sheet Temperature Range

Even temperature distribution throughout the sheet s thickness is recommended.

Acrylic sheet temperature range. The 3m adhesive transfer tapes with 3m high temperature acrylic adhesive 100 are designed for temperature exposure to 450 f 232 c for short periods of time and or solvent resistance. Acrylite ff sheet will soften as the temperature is increased above 195 f 91 c. The range is so wide because of the vast number of commercial compositions which are copolymers with co monomers other than methyl methacrylate. The forming range for acrylic sheet is 290 320ºf 142 160ºc.

The color is continuous throughout the material. As the temperature is increased the sheet passes through the thermoelastic state to the thermoplastic state. This is the maximum acceptable temperature above which mechanical properties tensile strength impact strength or electrical properties dielectric strength linked to insulation properties of a plastic part are significantly degrading over the reasonable life time of the tested product ul 746 is the test method generally used to calculate relative temperature index rti. It is an excellent material for bearings gears cams and other small parts.

Thermoplastic materials become liquid at their melting point 160 degrees celsius in the case of acrylic. A major useful attribute about thermoplastics is that theycan be heated to their melting point cooled and reheated again without significant degradation. They also offer low outgassing properties wh. The tg values of commercial grades of pmma range from 85 to 165 c 185 to 329 f.

Proper heating of the sheet is essential for successful thermoforming. It is recommended that temperatures not exceed 160 f 71 c for continuous service or 190 f 88 c for short intermittent use. High yield strength at elevated temperatures. Acrylic sheet 1 plexiglas t combines the beauty of plexiglas mc with additional toughness gained from the use of our advanced impact acrylic chemistry this union produces the aesthetics desired with increased toughness plexiglas t is more than 50 tougher than standard acrylic sheet.

Properties include low friction high wear resistance and ease of fabrication. Acrylite ff acrylic sheet can be used at temperatures from 30 f 34 c up to 190 f 88 c. The glass transition temperature tg of atactic pmma is 105 c 221 f. The forming temperature range is between 290 f and 320 f 143 c and 160 c.

The temperature of the sheet should be in the correct range but also uniform to achieve complete forming results. Before forming the sheet s temperature must be higher than the desired temperature to allow for cooling that will occur prior to the start of forming. Meets fda standards and is usda approved. It is available in colorless white and black in thick.

The service temp range is 20 to 185 deg f intermittent 200 deg f.
