Pengfeng proud to provide end customers with almost all the test data in our lab. To ensure safety, performance, and longevity, both cable materials (compounds) and finished cables must pass rigorous testing. Here’s a quick overview of the essential tests. 1. Tests for Cable Materials (Compounds)Before production, the raw materials are tested. Melt Flow Index […]
Inorganic Flame Retardants: Nature’s Fireproofing Heroes
Flame retardants act as invisible “firewalls” in everyday products like plastics, building materials, and wires. Among them, inorganic flame retardants stand out for being non-toxic, eco-friendly, and heat-resistant, making them the go-to choice over traditional halogen-based options. Let’s break down this “safety squad” in simple terms! 1. What Are Inorganic Flame Retardants? Definition: Mineral-based additives […]
China’s Kaolin: Two Very Different Stories from North and South
Kaolin, a valuable white clay mineral, is found across China. But its story changes dramatically depending on whether it comes from the South or the North. These two regions hold fundamentally different types of kaolin resources, shaped by nature in contrasting ways. 1. Southern Kaolin: Nature’s Ready-Made Gift How it Formed: Millions of years ago, hot and rainy weather […]
Comparison of Aluminum Hydroxid for PVC vs. HFFR Cables
In the wire and cable industry, PVC (Polyvinyl Chloride) and HFFR (Halogen-Free Flame Retardant) materials have fundamentally different flame retardancy requirements. Aluminum hydroxide (Al(OH)₃), as a key flame retardant, must be precisely selected to match each system. Below is a detailed technical comparison: 1. Core Flame Retardant Standards Comparison Parameter PVC Cables HFFR Cables Flame […]
Brucite: Revolutionizing Aluminum Composite Panels (ACP)
——The Mineral Core Behind High-End Cladding When skyscraper facades withstand blazing heat without warping, or subway station ACPs suppress fire and smoke, a white mineral from serpentinite ore—brucite (Mg(OH)₂—is replacing traditional aluminum hydroxide as the core filler. Its 340°C thermal stability, 2.38 g/cm³ low density, and halogen-free nature are redefining premium ACP standards. Why Brucite? […]
Aluminum Hydroxide (2-15μm): Four Key Applications Decoded
Precisely ground aluminum hydroxide (Al(OH)₃, 2-15μm) delivers irreplaceable value across four industries through tunable particle size, eco-friendly flame retardancy, and cost efficiency. A technical deep dive: 1. Thermal Insulation: Nano-Porous “Heat Shield” Mechanism 2-5μm particles: Create nano-pores (＞85% porosity) in ceramic fiber, reducing thermal conductivity to 0.032 W/m·K Endothermic phase change: Dehydration at 200°C (1970 J/g) […]

Is there no way to improve the thermal conductivity of aluminum hydroxide?
Breaking the Limits of ATH Thermal Performance Introduction: The Thermal Conductivity DilemmaAluminum hydroxide (ATH, Al(OH)₃) is a workhorse in polymer composites – renowned for its flame retardancy, low cost, and environmental safety. Yet its Achilles’ heel remains: extremely low thermal conductivity (0.2–0.3 W/m·K). This restricts its use in modern electronics where heat dissipation is critical. But […]
Pseudo-boehmite: The “Invisible Accelerator” for Concrete
——Industrial Alchemy of Amorphous Aluminium Hydroxide Behind the instant setting of shotcrete in tunnel engineering and high-speed precast production lines lies a white powder with 50% aluminum content—Amorphous Aluminium Hydroxide. This non-crystalline reactive alumina transforms saturated aluminum sulfate solutions into alkali-free accelerators, rewriting the rules of cement hydration. What Is It? Pseudo-boehmite is an amorphous aluminum […]
Aluminum Hydroxide: The “Flame Guardian” of HFFR Cables
——The Green Shield of Halogen-Free Safety When fire barriers in skyscraper cable shafts or subway tunnel cables must pass rigorous combustion tests, aluminum hydroxide (Al(OH)₃) silently safeguards power systems at >60% loading. As the core of Halogen-Free Flame Retardant (HFFR) compounds, it redefines “safe power transmission” with green chemistry. Why HFFR Cables Choose Aluminum Hydroxide? Three irreplaceable […]
