Glass Fiber Braided Heating Tape for Laboratory and Chemical Use

Glass fiber braided heating tapes are made with a core resistance heating element — commonly Nickel-Chromium (NiCr 80/20) or FeCrAl alloy — encased in layers of braided glass fiber insulation. The glass fiber serves as a high-temperature resistant protective layer that ensures durability and electrical insulation, while the alloy wire provides uniform heating. These tapes can withstand temperatures up to 450°C, making them suitable for laboratory, research, and chemical applications where stable and controllable heat is required.

Article: Glass Fiber Braided Heating Tape for Laboratory and Chemical Use

At DLX Alloy, we design and manufacture Glass Fiber Braided Heating Tapes that deliver precise and reliable heating for demanding laboratory and industrial environments. These tapes are built from high-grade resistance alloys combined with durable glass fiber insulation, offering both performance and protection for heat-sensitive processes.

Our product is engineered to maintain stable temperatures across equipment such as laboratory glassware, chemical reactors, pipelines, and distillation columns. Whether it’s for a small-scale experiment or an industrial pilot plant, DLX’s heating tapes provide consistent thermal output with superior safety and durability.

Material and construction excellence
Each heating tape starts with a carefully selected resistance wire — usually NiCr 80/20 or FeCrAl alloy — known for its stable resistivity and oxidation resistance. These wires are braided or spiraled within layers of glass fiber, which provides excellent electrical insulation and withstands continuous exposure to high temperatures.

Unlike plastic-insulated tapes, the glass fiber braided structure can operate at up to 450°C, making it ideal for high-temperature applications such as chemical synthesis, drying, or heat treatment. The braided sheath also provides mechanical strength, protecting the heating element from abrasion or chemical splashes.

The global demand for precision heating products has grown significantly across laboratory and chemical sectors. As industries adopt more automated and temperature-controlled systems, flexible heating solutions like DLX’s glass fiber tapes are becoming the preferred choice.

While traditional rigid heaters or electric mantles have limitations in coverage and efficiency, flexible heating tapes can conform to various equipment shapes, ensuring uniform heat transfer and reducing energy consumption. This adaptability aligns with modern laboratory needs where process flexibility and space efficiency are critical.

DLX’s manufacturing advantage
DLX stands out by maintaining complete control over the production chain — from melting and drawing alloy wires to assembling the final heating tape. This vertical integration allows us to customize every specification, ensuring our clients receive products tailored to their process parameters.

We apply strict testing standards, including insulation resistance, temperature uniformity, and thermal endurance tests, guaranteeing long-term reliability. Our heating tapes not only meet but often exceed industrial safety and performance requirements.

• Laboratories and research institutions: Heating flasks, columns, and vessels for reactions and distillations.

• Chemical and pharmaceutical plants: Maintaining consistent process temperatures in reaction lines and containers.

• Industrial maintenance: Dehydration and drying of equipment during servicing or assembly.

• Food and beverage production: Temperature control in ingredient processing and analysis.

• Power generation and petrochemical: Heating of fluid lines in cold or controlled environments.

DLX vs traditional systems
Traditional heating mantles or plate heaters are often limited by shape, requiring specific vessel dimensions and offering less uniform heat. In contrast, DLX’s glass fiber braided heating tapes are modular, adaptable, and energy-efficient, capable of wrapping around irregular shapes without compromising safety or performance.

DLX’s tapes are also lighter, easier to install, and require minimal maintenance compared to conventional heating systems, reducing both operational cost and downtime.
