Superior Heat Dispersion & Molten Metal Protection
Engineered for direct contact with extreme heat sources, this blanket uses a specialized vermiculite coating to shed molten metal splash and endure constant high temperatures where other blankets would degrade or fail.
Extreme Heat Resistance Our specialized vermiculite coating boosts the continuous operating temperature to 815°C (1500°F), providing a reliable shield against intense radiant heat and direct flame contact where other blankets would fail.
Superior Molten Metal Shedding Engineered to repel splatter from molten aluminum, copper, and steel. The unique coating forces droplets to bead up and roll off immediately, preventing the dangerous burn-through that can destroy standard fabrics.
Enhanced Abrasion Resistance The tough, canvas-like mineral coating creates a durable barrier that withstands heavy industrial wear, dragging, and abrasion common in foundries and fabrication shops, extending the product’s service life.
Understanding the Vermiculite Advantage
Our process begins with a high-performance fiberglass fabric base. We then apply a specialized coating of vermiculite—a naturally occurring mineral renowned for its exceptional heat insulation properties. When exposed to extreme heat, the microscopic platelets of the vermiculite expand and form a formidable insulating shield. This coating acts like a suit of armor for the base fabric, dispersing heat across the surface and dramatically increasing its temperature limit and durability.

Choosing the Right High-Temperature Blanket
To help you select the perfect product, this chart clearly compares our high-temperature solutions. While some may look similar, their performance is engineered for very different applications. Vermiculite coating is the superior choice for molten metal shedding and continuous heat exposure.
Customization for Your Industrial Application
As the direct manufacturer, our ability to create custom solutions is at the core of what we do. We go far beyond standard blankets, partnering with you to engineer custom furnace curtains, stress-relief pads, and precision-cut machinery drapes tailored to your exact dimensions. Every custom product is built for harsh industrial use, with available finishing options like high-temperature Kevlar thread stitching, heavy-duty stainless steel grommets, and reinforced hems to ensure maximum durability and performance in your specific application.
Vermiculite Coated vs. Heat Treated: Making the Right Choice
These two high-temperature blankets can look nearly identical due to their similar golden-brown color, but this color comes from two very different processes. The color of Heat Treated fabric is a result of a high-temperature purification process that caramelizes the fiberglass, while the color of Vermiculite Coated fabric comes from the natural mineral coating applied to its surface. This fundamental difference leads to very different performance capabilities.
- When to Choose Vermiculite Coated: Choose this blanket for maximum protection against molten metal splash, heavy abrasion, and the highest continuous heat, making it the premium choice for foundries and heavy welding.
- When to Choose Heat Treated: Choose this blanket when you need a softer, more flexible high-heat solution that is smoke-free on first use, at a more cost-effective price point for applications like wrapping pipes or general insulation.
Purpose-Built for Industrial Excellence
In a foundry environment, the primary danger is the accidental splash of molten metals like aluminum, bronze, or steel during transfer, pouring, or casting. Our vermiculite blanket acts as a critical line of defense. Its specialized coating creates a refractory surface that forces molten metal droplets to bead up and roll off immediately upon contact, preventing the dangerous burn-through that could destroy control cables, hydraulic lines, or injure personnel. It serves as an essential, movable shield for protecting high-value induction furnace components and surrounding structures.
Standard welding blankets can quickly degrade under the constant assault of high-amperage processes like arc gouging or plasma cutting, where sparks and molten slag are ejected at high velocity and temperatures exceeding 1,000°C. The superior abrasion resistance of our vermiculite coating is engineered to withstand this intense, repetitive mechanical and thermal abuse. It prevents damage to sensitive robotics, finished surfaces, and nearby flammable materials, reducing the risk of costly secondary ignition and ensuring a safer work zone.
For applications like Post-Weld Heat Treatment (PWHT), precise temperature control is not just a goal—it’s a requirement for ensuring the metallurgical integrity of the component. Uneven or rapid cooling can create residual stresses leading to brittle fractures and catastrophic failure. Our vermiculite blankets serve as flexible, reusable insulating wraps that conform to complex geometries like pipe joints and vessel nozzles. They ensure a slow, uniform cooling rate, helping you meet exacting engineering specifications and guaranteeing the long-term reliability of your critical assets.

FAQs About Vermiculate Coated Fire Blanket
A: The base fiberglass fabric and the vermiculite mineral coating are both excellent electrical insulators and are not conductive. However, while the material is safe, using a blanket is generally not the primary recommended method for extinguishing an active Class C (Energized Electrical) fire. The first step should always be to de-energize the circuit. The blanket is extremely effective for shielding nearby components from the heat and sparks of an electrical arc or for smothering the fire after the power has been cut.
A: It is specifically designed for high reusability in harsh environments. The tough vermiculite coating acts as a sacrificial layer that withstands repeated thermal shocks. While the surface may show cosmetic wear over time, the blanket maintains its structural integrity far longer than uncoated fabrics. We recommend a visual inspection for any physical damage after each use.
A: Yes, a small amount of smoke and a slight odor are normal on the first heat-up. This is the one-time burn-off of the organic binder used to adhere the vermiculite particles to the fiberglass. This process does not harm the fabric’s performance. We recommend performing the initial heat-up in a well-ventilated area.
A: Choose Vermiculite coated fire blanket for its higher continuous temperature limit (815°C vs. silicone’s ~260°C) and its superior ability to shed molten metal splash. Choose Silicone coated blanket for its flexibility, waterproof properties, and when protecting sensitive surfaces from scratches is a priority.
A: Absolutely not. All of our products are 100% asbestos-free. The materials we use are non-toxic and stable. As with handling any industrial fabric, we recommend standard PPE like gloves and safety glasses to prevent potential skin irritation from fibers during cutting or aggressive handling.
