The demand for flame retardants in the injection molding industry

27 Mar.,2025

 

With the increasingly strict global safety standards, especially in the fields of electronics, construction, automobiles, and home furnishings, the demand for flame retardant materials is gradually increasing. The injection molding industry, as an important part of plastic processing, is also facing increasingly high flame retardant requirements. Especially in some special applications, flame retardancy is not only related to product quality, but also involves personal safety and environmental protection. In order to meet these demands, the injection molding industry has begun to widely use flame retardants to enhance the safety of plastic products.
 

1. Background of the demand for flame retardancy in the injection molding industry
Injection molding is a manufacturing process in which plastic raw materials are heated to a molten state and then injected into a mold for cooling and forming. During this process, the flame retardancy of the material becomes an important factor affecting the safety of the final product. Especially in the fields of electronic device casings, wires and cables, automotive components, etc., the flammability of plastics can lead to catastrophic consequences in the event of a fire. Therefore, using appropriate flame retardants can effectively reduce the risk of fire and protect the safety of consumers' lives and property.

 

2. The function of flame retardants
Flame retardants are a type of chemical additive that can effectively delay or suppress the spread of flames, widely used in the production of various plastic products. Common types of flame retardants include halogen based, phosphorus based, inorganic based, and organic based flame retardants, each with different characteristics and application areas.

Halogen based flame retardants: have good flame retardant effects, but have gradually been phased out in recent years due to the potential release of toxic gases during combustion.
Phosphorus based flame retardants: They have good environmental performance and are commonly used in fields such as electronic product casings. They can effectively improve the thermal stability and flame retardancy of materials.
Inorganic flame retardants, such as aluminum hydroxide and magnesium hydroxide, have stronger environmental friendliness and are suitable for most injection molded products.

3. Case study: Flame retardant requirements for electronic product casings
Taking electronic product casings as an example, injection molded plastic casings face the risk of fire caused by electrical short circuits, overheating, and other factors during use. Therefore, the plastic casing of electronic products must have good flame retardant properties.
For example, a well-known electronics company produces smartphone cases using polycarbonate (PC) material containing phosphorus based flame retardants during the production process. This material not only provides excellent impact resistance, but also has a high flame retardant rating, meeting the UL94 V-0 flame retardant standard. This solution enables the company to meet the security requirements of electronic devices in different countries and regions worldwide.

 

4. Data support
According to market research firm Grand View Research, the global flame retardant market is expected to reach approximately $10 billion by 2025, with an average annual growth rate of 5.3%. Among them, the demand for flame retardants in the injection molding industry accounts for a large share, especially in the fields of electronic appliances, automobiles, and building materials, where the application demand has increased significantly.
For example, in 2019, the flame retardant market size of the US electronics and electrical industry was approximately $740 million, and is expected to grow to approximately $1.2 billion by 2025. The demand for flame retardants in the automotive industry in the European market is also showing a strong growth trend, mainly driven by the improvement of automotive safety standards and the rise of electric vehicles.

 

5. Future prospects
With the continuous improvement of environmental regulations, the demand for environmentally friendly flame retardants in the injection molding industry will become more urgent. In the future, environmentally friendly flame retardants such as low smoke halogen-free flame retardants and inorganic flame retardants will occupy a larger market share in the injection molding industry. In addition, with the advancement of technology, the development and application of new flame retardants will bring more innovative solutions to the injection molding industry, further improving the safety and environmental performance of plastic products.

 

6. Conclusion
In short, the application of flame retardants in the injection molding industry can not only improve the safety of plastic products, but also help companies meet increasingly strict regulatory requirements. With the increasing concern of consumers for safety and environmental protection, the demand for high-performance, low toxicity, and environmentally friendly flame retardants in the injection molding industry will continue to grow. For flame retardant manufacturers, this is both a challenge and an opportunity to provide innovative solutions.
