Characteristics

Material Profile

ML-FJ1251R is a radiation cross-linkable halogen-free flame retardant polyolefin compound designed for flexible cable insulation and sheathing. The base polymer system undergoes electron beam irradiation to form a three-dimensional network structure, enhancing thermal stability and mechanical strength. This compound produces low smoke and non-corrosive gases during combustion, with no halogens (chlorine, bromine, fluorine, iodine) in the formulation. The cross-linked structure enables 125°C continuous operation while maintaining flexibility for cable handling and installation in photovoltaic systems and industrial applications.

FAQ

Common Questions and Technical Notes

What is the recommended irradiation dosage for 1.5mm wall thickness?

For insulation thickness of 1.5mm, a dosage of 100-120 kilograys typically achieves gel content above 60 percent. Dosage should be validated through sample testing.

Can this compound be used without cross-linking?

No. ML-FJ1251R requires radiation cross-linking to achieve 125°C temperature rating and mechanical properties. Uncured material has limited thermal performance and should not be used in final cable construction.

Is this material suitable for thin-wall insulation (0.5mm or less)?

Yes. The formulation maintains smooth surface finish at wall thicknesses down to 0.4mm. Lower irradiation dosage (70-90 kGy) may be required for thin walls to avoid embrittlement.

What is the shelf life before irradiation?

9 months in original sealed packaging stored at 5-30°C. Material should be protected from UV and high humidity. After irradiation, shelf life exceeds 10 years under normal storage conditions.

Does the compound contain any antimony trioxide?

No. The flame retardant system is based on phosphorus-nitrogen chemistry without antimony trioxide or halogenated flame retardants.

Typical color options for photovoltaic cable identification?

Black (UV stabilized for sheath), red, white, blue, green, yellow, and green-yellow stripe for insulation. Custom colors available with validation of flame and mechanical properties.

Storage and Handling Notice

Store ML-FJ1251R in original sealed polyethylene bags at temperatures between 5°C and 30°C. Avoid direct sunlight, ozone, and high humidity. The compound is hygroscopic; moisture content above 0.15 percent causes surface defects during extrusion. Once opened, use within 2 weeks or reseal with desiccant. Unused material exposed to ambient conditions for more than 4 hours must be re-dried at 70°C for 3 hours before extrusion. Keep away from open flames during processing. Cross-linking by electron beam must be performed within 6 months of extrusion for optimal gel formation.
