Did you know that nearly 25% of industrial fires can be attributed to electrical failures or malfunctions? In such high-risk environments, the need for flame-retardant silicone material becomes paramount. The UL 94 V-0/HB, is a critical standard for assessing the flammability of plastic materials, including rubber. Understanding UL 94 HB is essential for industries that require materials to exhibit fire resistance, particularly in the production of fire-retardant gaskets, fire-retardant seals, and various extruded rubber products.

What is UL 94 HB
UL 94 V-0/HB is a horizontal burn test developed by Underwriters Laboratories (UL), a global safety certification company. This standard assesses the material’s ability to resist burning and its effectiveness in slowing down the spread of flames. The “HB” in UL 94 HB stands for “Horizontal Burn,” indicating that the test evaluates the material’s performance when subjected to a horizontal flame.
The test involves exposing a specimen to a 20 mm high flame for 30 seconds. The material must have a thickness between 3 to 13 mm and should burn at a rate of less than 40 mm per minute for thicker specimens, and less than 75 mm per minute for thinner specimens.
If the flame extinguishes before reaching the first mark on the material, it achieves a 0 mm/min burn rate, the highest level of fire resistance under this standard.
Importance of UL 94 HB in Flame Retardant Gaskets and Seals
Flame retardant gaskets and seals are crucial in various applications where safety and reliability are paramount. UL 94 HB/V-0-rated materials ensure that these products can withstand high temperatures and resist burning. This is essential in environments prone to fire hazards. These gaskets and seals are commonly used in industries such as electronics, automotive, aerospace, and construction.
Applications in Extruded Rubber and Silicone Rubber Products
Extruded rubber, particularly silicone rubber, is widely used to manufacture gaskets and seals that require fire-retardant properties. Silicone rubber is especially valued for its excellent thermal stability, electrical insulation properties, and resistance to environmental factors such as UV radiation and ozone.
For instance, in data centers, UL 94 HB silicone rubber gaskets and seals play a vital role in ensuring the safety of electrical and electronic components. These components generate significant heat, and the surrounding materials must prevent the spread of potential fires. Fire retardant door gaskets and HVAC seals are typical applications in such settings, providing both protection and efficiency.
Manufacturing UL 94 HB Flame Retardant Gaskets
Creating UL 94 HB flame retardant gaskets involves precision and adherence to strict standards. At Elastostar, we source UL 94 HB-rated rubber in sheets or custom-sized pieces and use advanced manufacturing techniques to fabricate the final products.
Water jet cutting is one such method that allows for precise, clean cuts without the need for expensive tooling, making it ideal for producing low-to-medium volume quantities.
In addition to cutting, our services include gasket bonding, parts marking, kitting, and custom packaging. We also offer storage solutions to ensure that the materials are readily available to meet our clients’ production schedules and demand forecasts.
Benefits of UL 94 HB Rated Materials
Choosing UL 94 V-0/ HB-rated materials for fire retardant gaskets and seals offers several advantages:
- Enhanced Safety: These materials help prevent the spread of fire, providing critical protection in high-risk environments.
- Regulatory Compliance: Using UL 94 HB-rated materials ensures compliance with safety regulations and standards.
- Durability: These materials offer long-lasting performance, even under extreme conditions, reducing the need for frequent replacements.
- Versatility: Suitable for a wide range of applications, from automotive to aerospace, enhancing product reliability and safety.
