HZD2720-L
HZD2720-L is a 125°C irradiation cross-linked LSZH polyolefin cable compound — FT2 rated, colorable, meets UL 758 / UL 1581 mechanicals for 125°C XLPE and runs on ordinary PVC extrusion lines.
Blue cable compound pellets for wire and cable manufacturing
01 / 02Material — Irradiation cross-linked LSZH polyolefin (XLPO) compound
Overview
HZD2720-L is a 125°C halogen-free flame-retardant cable compound, colorable, built on a polyolefin base with inorganic flame retardants, antioxidants and lubricants, internally mixed, plasticized and pelletized. It serves electronic and electrical equipment wire, communication wire, building wire and instrumentation cable.
The grade extrudes on ordinary PVC equipment with a smooth, round wire surface. Its mechanical performance meets the UL 758 and UL 1581 requirements for 125°C XLPE, and the designed flame-retardant class is FT2.
Packaging & Storage
Supplied in aluminum-plastic bags with kraft paper lining, 25 kg net per bag. Store in a dry, well-ventilated warehouse.

Grade qualification
Validate the grade against the cable, process and target standard
Published properties establish the review baseline. Cable construction, processing conditions and a line trial complete the grade decision.
- 01
Define the duty profile
Confirm cable construction, operating temperature, flame class and environmental requirements.
- 02
Review the published data
Match requirements, typical values and test methods to the finished-cable target.
- 03
Run a controlled line trial
Set drying, temperature, screw and irradiation conditions from the grade processing card.
- 04
Approve the production window
Record surface, dimensions, mechanical results and finished-cable tests before volume production.
