1. What Is UL94 Rating?
These UL94 ratings are important to ensure the safety of plastic components in many different applications
The UL94 rating is known as the standard for the flammability of plastic materials used in appliances and equipment. This is a very popular standard developed by Underwriters Laboratories (UL). First of all, this rating measures the ease with which a material can catch fire. In addition, this UL94 standard helps evaluate the speed at which the material extinguishes after it catches fire. These UL94 ratings are important to ensure the safety of plastic components in many different applications. In particular, UL94 ensures the safety of places that are prone to fire and explosion such as electronic equipment, technical equipment, and household appliances. Therefore, UL94 is very important in ensuring compliance with fire prevention regulations to maintain product quality and ensure consumer safety. UL94 is also a rating that helps facilitate the market acceptance of products made from plastic materials more convincingly.
2. All Types Of UL94 Flame Retardant Standards
The UL94 rating includes several different classifications. Each classification is designed to measure the flammability properties of plastic materials under different conditions. UL94 helps manufacturers and engineers select the right materials for applications that require good flame resistance. Here are the UL94 flame resistance standards.
UL94 standard helps evaluate the speed at which the material extinguishes after it catches fire
2.1. Horizontal (HB)
Materials thinner than 3 mm have a standard velocity of less than 76 mm/min. Materials between 3 and 13 mm thick have a standard velocity of less than 40 mm/min. Plastic materials that commonly apply this type of UL94 rating include common plastics used in household items, housings for appliances, toys and electronic devices, etc. Especially ABS plastic used in keyboard cases.
2.2. Vertical (V)
V-0: UL94 rates materials that will stop burning within 10 seconds after the flame is removed and no flame droplets fall. This UL94 rating is typically applied to high-performance electronic equipment materials such as circuit boards, connectors, and enclosures for electrical equipment. For example, Polycarbonate and some types of nylon are common materials in this category.
V-1: Here UL94 rates the material as stopping burning within 30 seconds after the flame is removed and no flame droplets fall. This UL94 rating can be applied to materials used in applications that require moderate flame resistance. Some examples include enclosures for office equipment or automotive interior parts. Specifically, Polypropylene with flame retardant additives can achieve a V-1 rating.
V-2: This is when the material stops burning within 30 seconds after the flame is extinguished. UL94 allows the material to continue dripping as long as it does not ignite. This UL94 rating applies to materials used in applications requiring basic flame resistance, such as the enclosures of some consumer electronics. Typical examples include lower-grade polycarbonates or composites that may achieve a V-2 rating.
UL94 ensures the safety of places that are prone to fire and explosion such as electronic equipment, technical equipment, and household appliances
2.3. Longitudinal (5V)
5VA: The material ceases burning within 60 seconds after five five-second flame applications and does not develop any drops or holes. This UL94 rating applies to plastic materials used in demanding applications such as aerospace, medical devices, and industrial equipment. Some high-performance plastics such as PEEK (polyether ether ketone) may achieve a 5VA rating.
5VB: The material ceases burning within 60 seconds after five five-second flame applications, but may develop holes. This UL94 rating applies to materials used in automotive parts applications, heavy duty electrical enclosures, and some industrial applications. Modified polycarbonate or some flame retardant nylon materials may achieve a 5VB rating.

2.4. Longitudinal for thin materials
VTM-0: For thin materials, the material ceases to burn within 10 seconds after the flame is extinguished, with no flame droplets. This UL94 rating applies to thin films and shields. Some common items include insulating films for capacitors, flexible printed circuit boards, or thin protective covers. Some types of polyester films typically meet this UL94 standard.
VTM-1: For thin materials, the material ceases to burn within 30 seconds after the flame is extinguished, with no flame droplets. This UL94 rating applies to thin materials used in applications requiring moderate flame resistance such as thin insulation, tapes, and some thin-walled piping. Some polyethylene films may achieve a VTM-1 rating.
VTM-2: For thin materials, the material ceases to burn within 30 seconds after the flame is removed, but flame droplets are permitted. This UL94 rating applies to thin materials used in applications requiring moderate flame resistance. Certain thin acrylic or PVC films may achieve a VTM-2 rating.
UL94 brings enormous benefits to both manufacturers and consumers
2.5. Horizontally for foam materials
HF-1: The material ceases to burn within 2 seconds after the flame is removed, with no flame droplets. UL94 is rated for foams used in critical applications such as medical devices, automotive interior components, and advanced packaging materials. Examples include some polyurethane foams.
HF-2: The material ceases to burn within 2 seconds after the flame is removed, but flame droplets are allowed. UL94 is rated for foam materials used in applications requiring moderate flame resistance such as furniture padding, mattresses, and automobile seats. Some flexible polyurethane foams can achieve an HF-2 rating.
HBF: The material burns at a slow rate without flame droplets. UL94 is rated for foam materials used in applications requiring minimal flame resistance such as basic packaging foam, some upholstery foams, and craft foams.
