Silane‑Crosslinked Flame‑Retardant PE Compound for PV Cable (YHS9‑PV)

YHS9‑PV

YHS9‑PV is a silane‑crosslinked flame‑retardant polyethylene insulation compound for sioplast process. It consists of three components: base material YHS9‑PV‑A, catalyst YHS9‑PV‑B and flame‑retardant masterbatch YHS9‑PV‑C. The compound complies with UL44 and UL4703 standards and achieves FT‑1 and FT‑2 flame‑retardant grades. It delivers high tensile strength, excellent elongation, stable thermal‑aging performance and low dielectric loss. After blending of A/B/C components, cables can complete cross‑linking via hot‑water or steam curing; opened component‑A shall be consumed within 24 hours to avoid premature cross‑linking.
