Introduction of Melinex® FR320/FR321 flame retardant clear polyester films
On April 29, 2020, DuPont Teijin Films introduced a major innovation in flame-retardant polyester films: Melinex® FR320/FR321 clear PET films. These films have received UL certification for VTM-0 flame retardancy classification according to ANSI/UL 94 and are halogen-free. This property makes them particularly attractive for applications in industries that place high demands on fire safety, such as the automotive, electronics, construction and transportation sectors.
Technical properties of Melinex® FR320/FR321 PET films
Melinex® FR320/FR321 films offer a combination of physical durability, chemical resistance, low water absorption and overall reliability at an affordable price. With a low haze of around 1 percent and thicknesses from 75 µm to 175 µm, these films are available in roll widths up to 1600 mm and beyond. Typical applications include laminate structures for construction and transportation, battery labels and insulation materials, lighting and flexible printed circuits.
Processing options at Dr. Dietrich Müller GmbH
Dr. Dietrich Müller GmbH uses its extensive experience and advanced equipment to process materials such as Melinex® FR320/FR321 films through various techniques:
1. Punching
Punching is one of the core competencies of Dr. Dietrich Müller GmbH. With precise punching tools and modern machines, a wide variety of shapes and patterns can be punched out of the flame-retardant PET films. This method is ideal for the production of seals, insulation materials and components that require high dimensional accuracy.
2. Cutting
Melinex® FR320/FR321 films are cut using high-precision cutting equipment that ensures clean and precise edges. This technique is ideal for creating strips, panels and other specific cuts used in the electronics, construction and transportation industries. The ability to cut films in different widths and lengths offers customers flexibility and customized solutions.
3. The shape
The molding technology allows the PET films to be transformed into complex geometries that meet the specific requirements of customers. Thermoforming and other processes can be used to produce three-dimensional structures that are used in applications such as housings, covers and special insulation solutions. The formability of Melinex® FR320/FR321 films opens up new possibilities for innovative designs and functional components.
Applications and Benefits
The flame-retardant Melinex® FR320/FR321 clear polyester films offer a wide range of benefits for different industries. The UL VTM-0 classification and the halogen-free nature mean they meet strict safety and environmental standards. Typical applications include:
- Laminate structures: These films can be used in multilayer structures to provide improved fire safety and mechanical stability.
- Battery labels and insulation materials: Thanks to their chemical resistance and low water absorption, they are ideal for the labelling and insulation of batteries.
- Lighting: The low haze of the films provides clear and bright lighting conditions, making them attractive for lighting applications.
- Flexible printed circuits: The mechanical durability and flexibility of the films make them an excellent choice for flexible electronic components.
