UL-94 VTM-0 flame retardant label
UL flame retardant PET label is a type of label made of 2mil (50& mu; m) thick polyester film as the substrate and coated with a printable coating polyester label, with a permanent acrylic pressure-sensitive adhesive, particularly suitable for printing and heat transfer printing; This label is a halogen-free flame retardant label with a fire retardant rating that meets the UL94 VTM-0 standard requirements; Save your labeling costs while ensuring high quality
Features:
1. Designed according to UL94 VTM-0 standard requirements, the unique flame retardant coating and adhesive have excellent flame retardant effect, and there are no molten droplets after ignition
2. The surface coating can meet various printing and printing requirements and provide strong resistance
3. Compliant with ROHS and halogen-free environmental requirements
4. Complies with GB/T25978 standard
5. UL and CUL numbers: E358889 # 608
Suitable for product identification with fire and flame retardant requirements in electronics, automobiles, aviation, cables, power supplies, etc., especially for battery label applications. In laptop, mobile phone, and other battery module applications, it can not only be used as a choice of label material, but also as a thermal insulation and flame retardant protective layer
UL flame retardant and high-temperature resistant label usage
The material is suitable for harsh environments, including applications that require the material not to spread flames. If exposed to flames, label design is to prevent the spread of flames. The label adopts a unique combination of surface coating, polyimide film, and adhesive to provide flame retardant performance to meet the UL94 VTM-0 standard. In addition, the implementation of flame retardant performance does not use halogenated flame retardant materials, making it suitable for electronic applications.
Flame retardant labels are designed for harsh environments and can be printed with barcode, graphic, or text information using thermal transfer or flexographic ink systems. When printed with an appropriate heat transfer ribbon, the label is resistant to chemical exposure such as isopropanol, terpenes, and saponification agents. Even if the material is directly exposed to friction or accidental contact, the image will not be stained.
What is UL flame retardant label?
The UL flame retardant label refers to a safety certification mark obtained by a product after passing UL (Underwriters Laboratories) flame retardant testing. This symbol represents that the product has passed UL's rigorous safety assessment and meets UL's flame retardant performance standards. As a globally renowned safety certification body, UL's flame retardant label is widely recognized as an authoritative symbol of product quality and safety.
Specifically, the UL flame retardant label indicates that the product material has certain flame retardant properties under specific testing conditions, that is, the material can quickly extinguish after being ignited and will not continue to burn or cause a fire. This is crucial for many industries such as construction, electronics, automotive, medical equipment, etc., as their products may come into contact with sources of fire during use, and therefore must have certain flame retardant properties to ensure safe use.
Standard for UL flame retardant labels
The UL flame retardant label standard is a series of testing standards for material flame retardancy developed by Underwriters Laboratories (UL) in the United States. These standards typically include various testing methods such as vertical combustion testing, horizontal combustion testing, and ultimate oxygen index testing to evaluate the flame retardant performance of materials under different conditions.
Specifically, the standards for UL flame retardant labels may involve the following aspects:
Vertical combustion test: a testing method for evaluating the combustion performance of materials when placed vertically, by observing indicators such as the combustion speed and flame spread length of the sample to assess the flame retardancy of the material.
Horizontal combustion test: a testing method for evaluating the combustion performance of materials when placed horizontally, which also evaluates the flame retardancy of materials by observing indicators such as the combustion speed and flame spread length of the sample.
Extreme Oxygen Index Test: A test method for evaluating the minimum oxygen concentration required for a material to maintain combustion at a specific oxygen concentration, used to determine the flame retardant performance level of the material.
It should be noted that the standards for UL flame retardant labels are not static. With the development of technology and the improvement of safety standards, UL will continuously update and improve its flame retardant testing standards. Therefore, in specific applications, it is necessary to refer to the latest UL flame retardant testing standards to evaluate the flame retardant performance of the product.
