When a firefighter charges into an 800°C inferno, the protective gear on his back is literally a countdown timer against death. Traditional insulation layers often fail within 8 minutes at 500°C (per GA 634-2006 firefighter insulation standards). The “Golden 90 Seconds” of rescue can be lost to heavy, cumbersome equipment. In -60°C polar expeditions, explorers rely on bulky down suits that severely limit mobility. Is there a material that can simultaneously extend those precious minutes of life and restore agility to those who protect us? The answer is Hebei Woqin’s aerogel felt. Core performance (validated per GA 634-2006 and multiple extreme environment tests): • Thermal conductivity as low as 0.018 W/(m·K) — one-third lower than still air (~0.026 W/(m·K)) and roughly half that of typical Nomex felt (~0.04 W/(m·K)) • A 1 cm sheet blocks 1300°C flames with back-side temperature rise of only 2.8°C per minute • Adding a 0.6 mm aerogel composite layer keeps inner temperatures below 60°C for 15 minutes at 650°C — far exceeding the standard 8-minute requirement • In 800°C environments, aerogel-reinforced gear has supported continuous operation for up to 25 minutes • Gear weight reduced by at least 23%, delivering critical mobility during the “Golden 90 Seconds” of rescue • Metallurgy suits: thickness reduced from 8 mm to 3 mm while thermal burn risk drops 82% • Welding gloves: fingertip sensitivity improved by 37% • Polar expedition suits: 40% thinner than traditional down yet 60% better insulation (field-proven at −40°C to −60°C) Hebei Woqin: not just a material supplier, but a trusted partner collaborating with leading protective equipment manufacturers to develop ready-to-use thermal insulation solutions.

                                 

Single-Coat gAerogel Coatin: Spray-On 800μm Thermal Barrier That Defies 1200°C for Complex Industrial Assets

To Plant Managers, Maintenance Engineers, and Project Leaders:

For years, the most frustrating insulation problems haven't been the long, straight pipes — they've been everything else: the valves, elbows, flanges, pumps, vessel skirts, and irregular surfaces that are impossible to wrap properly. Traditional solutions — multi-layer wraps, custom-fabricated jackets — are labor-intensive, prone to failure, and require frequent, costly rework, leading to sustained heat loss, safety hazards, and endless budget overruns.

In an era where global industry is racing toward higher energy efficiency and asset integrity, these “impossible-to-insulate” surfaces have become a critical bottleneck. At Hebei Woqin, we've spent over a decade mastering aerogel technology. This deep expertise led us to a definitive answer: a single-coat, spray-applied aerogel insulation coating that performs where wraps cannot — and keeps performing for years.

Part 1: The Core Innovation – Simplicity Meets Extreme Performance
We engineered this coating with one overriding goal: to make high-performance insulation as simple as painting a wall.

  • One-Pass Application — Apply 600 to 1000 microns (0.6 to 1.0 mm) of continuous insulation in a single spray coat. This eliminates the complexity, time, and potential for error inherent in multi-layer systems.
  • The Science Behind It — The coating is a sophisticated dispersion of hydrophobically modified aerogel particles (surface area >700 m²/g) within a high-temperature, inorganic silicate binder. Upon curing, it forms a monolithic, nano-porous matrix that traps air at a microscopic level, creating an exceptional thermal barrier with inherent durability and strong adhesion.

Part 2: Verified Performance – Data from the Lab and the Field
Our claims are backed by stringent third-party testing and, more importantly, documented field results.
