01 / 02Material — Irradiation cross-linked polyolefin heat-shrink masterbatch
Overview
HZD1610 is an irradiation cross-linked, flame-retardant heat-shrink tubing masterbatch rated at 125°C. It is compounded from a polyolefin base resin with flame retardants, antioxidants and lubricants, then melt-mixed, plasticized and pelletized. The grade is designed for UL and CSA style heat-shrink tubing: finished tubes meet UL 224 and are used for cable joints, pipe connections, insulation of electronic components and bundling of stranded wires.
HZD1610 combines good mechanical performance with easy processing on standard tube extrusion equipment, at a highly competitive cost-performance ratio.
Packaging & Storage
Supplied in paper-plastic compound bags, 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.
