Properties of stretched acrylic sheets
Stretched acrylic sheets are issued according to the following specifications:
ÒÓ 2216-005-25558743-2001 (letter À) - Aviation stretched organic glass grade AO-120À(amendment 4);
ÒÓ 6-02-5757599-121-90 - Aviation stretched organic glass grade AO-120 (amendment 1, 2, 3)
ÒÓ 6-01-1348-87 stretched organic glass grade ÑÎÎÒ
The grade ÀÎ 120À is issued by thickness from 2 up to 18 mm and the linear sizes of sheets of the rectangular form 1700õ1850 and 2050õ2300 mm
The grade ÀÎ 120 is issued by thickness from 1 up to 12 mm and the linear sizes of sheets of the rectangular form from 1450x1450 up to 1600x2100 mm depending on the thickness.
Delivery of the sheets made on the consumer patterns and cutting maps is possible.
Mechanical properties of all grades of a stretched organic glass are practically identical
