Secondary coating material for optical cable (PBT)

Short Description:

PBT material for optical fiber loose tube is a kind of high performance PBT material obtained from common PBT particles after chain expansion and tackification. It has excellent properties of tensile resistance, bending resistance, impact resistance, low shrinkage, hydrolysis resistance, etc., and has excellent processing performance and good compatibility with common PBT color masterbatch. It is applied to micro cable, belt cable and other communication cables.

Standard: ROSH

Model: JD-3019

Application:Applied to produce optical fiber loose tube
