This client specializes in flame-retardant cables for the construction industry, with products exported to the EU and Southeast Asia. With the EU’s CPR regulations raising standards for smoke density, toxicity, and fire resistance, their existing aluminum hydroxide flame-retardant system faced major challenges:
- Excessive smoke density: Light transmittance during combustion was only 35% (standard ≥60%).
- Decline in mechanical performance: At a loading level of 150 phr, cable tensile strength was more than 20% below the required standard.
- Processing difficulties: High filler content caused rough extrusion surfaces and increased scrap rates.
Our company offers the Br-5000 magnesium hydroxide (Mg(OH)₂) flame retardant, designed to address key challenges:
- Low-smoke, halogen-free performance: High decomposition temperature (340°C) releases pure water vapor during combustion, raising smoke transmittance to 78% (EN 61034). Free from halogens and heavy metals, it meets EU CPR and IEC 60754 toxicity standards.
- Balanced performance design: Particle size D50 = 5 μm with advanced surface modification. At a loading of only 120 phr, the material achieves UL94 V-0 rating. Excellent compatibility with base resins ensures a tensile strength retention rate above 90%.
- Production support: Customized extrusion process parameters eliminated surface defects, increasing extrusion speed by 15%.
- Certification success: Achieved RoHS compliance and became one of the few domestic cable producers meeting EU standards.
- Cost efficiency: Reduced flame-retardant cost per ton of cable by 8% compared to the previous system.
- Market growth: Export orders rose by 40% year-over-year.
“JINGHUA’s magnesium hydroxide flame retardant helped us overcome key technical challenges. Our cables now not only meet the strictest EU standards but have also earned green building credits in multiple international projects. We have since extended this solution to our photovoltaic cable product line.”
