Politereftalan etylenu D2
Polyethylene terephthalate grade D2 – for the manufacture of textile yarns, nonwovens and polyester fiber.
Physical and chemical properties of the polyethylene terephthalate:
|Weight of 100 pellets, g||4,0±0,5|
|Specific viscosity in dichloroacetic acid, units||833±7|
|Titanium dioxide content, %||0,30±0,02|
|Moisture (water) content, % w/w, not more than||0,1|
|Color difference coordinates CIE 1976 with illuminant D65, geometry d/8°(d/10°) specular component excluded: L*, units, not less than b*, units, not more than||80 5|
