For optical fiber loose tube, the most common feedstock is PBT. In terms of hydrolysis resistance ability, PBT is inherently inferior to Nylon 12. However, Shinkong successfully improves hydrolysis resistance performance on SHINITE® PBT loose tube grade and received recognition from most major manufacturers for optical fiber loose tube. That’s why SHINITE® PBT loose tube grade is your best choice for optical fiber loose tube feedstock.

Currently Shinkong provides several grades on loose tube application, including:
SHINITE® D201G00NA DK5006 – IV 1.20;
SHINITE® D201000NA DHK011 – IV 1.20, economical grade;
SHINITE® D201G00NA DK5016 – IV 1.25;
SHINITE® D201G00NA DK5130 – IV 1.30;
SHINITE® D201G00NA DK5138 – IV 1.38,

where IV – intrinsic viscosity.
