Knowledge about PVC flame retardant film

Flame retardant PVC soft film

Flame retardant PVC soft film is a specially treated PVC soft film with flame retardant properties. The following is a detailed introduction about it:

1. Materials and processes for production: Material: Composed of PVC resin, flame retardant plasticizer, and other additives. The selection and ratio of these raw materials are crucial for the performance of flame-retardant PVC soft film, and high-quality plastic agents and flame retardants can ensure good flame retardant effects.
• Process: Usually processed using rolling technology. This process can evenly shape the material, ensure the thickness uniformity and quality stability of the film, and thus evenly distribute the flame retardant performance throughout the film.
2. Performance characteristics:
Flame retardant performance: This is its most prominent feature. Compared with ordinary PVC soft film, flame-retardant PVC soft film is not easily ignited. When it comes into contact with a fire source, it can prevent the spread of flames and automatically extinguish after leaving the fire source. This characteristic makes it widely used in places with high fire prevention requirements, such as shopping malls, hotels, exhibition halls, and other densely populated public places.
• Physical properties: It has a certain degree of flexibility and strength, and can adapt to different shapes of object surfaces for bonding and wrapping. At the same time, it also has good wear resistance, corrosion resistance and aging resistance, and its service life is relatively long.
Chemical stability: It has a certain tolerance to chemicals such as acids, bases, and salts, is not easily corroded by chemicals, and is suitable for various complex chemical environments.
• Environmental friendliness: If environmentally friendly raw materials and production processes are used, flame-retardant PVC soft film can meet certain environmental standards with minimal impact on the environment and human health.
3. Application areas:
Indoor decoration: can be used for ceiling and wall decoration, not only for aesthetic purposes, but also to meet the fire prevention requirements of buildings. For example, in the interior decoration of some large shopping malls and office buildings, flame-retardant PVC soft film is often used to create unique decorative effects.
Advertising promotion: used to create promotional materials such as lightbox advertisements and posters. Due to its excellent transparency and color saturation, it can present clear and vivid images, while also possessing flame retardant properties, ensuring the safety of advertising venues.
In the industrial field, it can be used as insulation and protective materials in electrical equipment, electronic instruments, and other fields. For example, it is used to wrap wires and cables, providing insulation and flame retardancy to prevent electrical accidents from occurring.

4. Market prospects: With the increasing emphasis on fire safety and the increasingly strict fire protection requirements of relevant laws and regulations for building and decorative materials, the market demand for flame-retardant PVC soft film will continue to increase. In the future, the development trend of the market will be to develop flame-retardant PVC soft films with better performance and environmental friendliness.

The grade of flame-retardant PVC soft film
  The grades of flame-retardant PVC soft film mainly include the following: V-0, V-1, V-2 grades: These are flame retardant grades classified according to UL94 standards. V-0 grade indicates that under the action of flames, PVC material will self ignite for no more than 10 seconds and will not produce droplets. V-1 level indicates that the self ignition time does not exceed 30 seconds and no droplets will be produced. V-2 level indicates that the self ignition time does not exceed 30 seconds and may produce a small amount of droplets;
 B1 level: This is the flame retardant level classified according to DIN 4102-1 standard. B1 grade materials have flame retardant properties under certain conditions, with a slower combustion rate and a smaller range of flame propagation. By adding appropriate flame retardants, PVC plastic can reach B1 level, which can slow down the combustion rate and prevent the rapid spread of flames when encountering small fire sources;
 Grade A: Grade A soft film has excellent fire resistance and is divided into A1 and A2 grades. A1 level detects non combustibility and total calorific value, A2 level detects non combustibility and SBI monomer combustion test (or total calorific value and SBI monomer combustion test, one of which is optional). A-grade soft film is particularly suitable for use in public places with strict fire safety requirements, such as hospitals, schools, etc;
Testing methods and standards
UL94 standard: This standard divides the flame retardant rating of PVC materials into three levels: V-0, V-1, and V-2. Each level has specific regulations on the combustion time, self extinguishing ability, and residual length of the sample;
DIN 4102-1 standard: This is a European standard that divides the flame retardant rating of PVC materials into multiple levels, including HB, V-2, V-1, and up to 5VA
Application scenarios
PVC soft film is suitable for different scenarios under different fire resistance levels. A-grade soft film is suitable for public places with strict fire prevention requirements, such as hospitals, schools, etc. B1 grade soft film is suitable for places that require certain fire resistance, while V-0, V-1, and V-2 grade soft films are suitable for places that generally require flame retardant performance.
