Organic structural sheet (K) and for glazing of aircraft (A)
(GOST 10667-90)
It is a plasticized and non-plasticized polymer of methyl methacrylic acid ester.
Depending on the purpose, the following brands are produced:
aviation (A) — for glazing aircraft, helicopters, boats.
structural (K) — is used as a structural material for instrumentation and aggregation and for the manufacture of technical products in engineering and other industries.
It is supplied in the form of transparent, unpainted sheets of rectangular shape with edges of the following sizes cut off and uncrossed (in agreement with the consumer):
width (400-1400) mm;
length (500-1600) mm;
thickness (0,8-30) mm.
The warranty period of storage is 2 years.
СО-95А, СО-95К — organic plasticized glass
СО-120А, СО120К — organic glass unplasticized
СО-133К — organic copolymer glass
