Sheets of polyolefins:
polyethylene and polypropylene
TU 2246-048-00203387-98
Sheets of polyolefins - polyethylene (PEVD - high pressure polyethylene, PEND - High Density Polyethylene) and polypropylene (PP) intended for the manufacture of products for the national economy termoformovaniya method, as well as facing, corrosion-proof, an ornamental material for lining bunkers, techek, craters to prevent adheres. Sheets made of polypropylene is also used as a substitute lighting sheets for the production of canopy lighting fixtures daylight.
Temperature for the sheets:
PEVD from -40 C to +70 C;
PEND from -40 C to +100 C;
PP from -15 C to +120 C.
The sheets are made of extrusion grades of polyethylene low pressure core brands 20808-024, 20908-040, songs polyethylene grades 273-79, 276-73 GOST 16338, stamps 273-83 TU 2243-104-00203335; high-pressure polyethylene core brands 10803-020 ,15803-020 ,15303-003 GOST 16337; polypropylene grades 01003-01030 GOST 26996, TU 2211-015-00203521. Permissible to use other brands of polyolefins domestic and foreign production, as well as tracks and mixes on their base and technological waste of the stamps.
