Flame retardant selection guide for novice manufacturers
For novice manufacturers, correctly selecting flame retardants is a key step to ensure product safety performance. The following provides a practical guide for novice manufacturers to select flame retardants from several key aspects.
Introduction:
For novice manufacturers, correctly selecting flame retardants is a key step to ensure product safety performance. The following provides a practical guide for novice manufacturers to select flame retardants from several key aspects.
Identify the types and characteristics of flame retardants
Flame retardants mainly include halogen, phosphorus, nitrogen and inorganic flame retardants.
1. Halogen flame retardants have high flame retardant efficiency and are suitable for a variety of polymer materials, but some products may produce harmful gases when burned, and environmental protection regulations need to be paid attention to.
2. Phosphorus flame retardants have both flame retardant and plasticizing effects, good thermal stability, and are suitable for thermoplastics, etc.
3. Nitrogen flame retardants are environmentally friendly and have low smoke emission, and are often used in combination with other flame retardants.
4. Inorganic flame retardants such as aluminum hydroxide and magnesium hydroxide have the advantages of non-toxicity and smoke suppression. They are mostly used in fields with high environmental protection requirements, but large additions may affect material performance.
Manufacturers need to preliminarily screen suitable flame retardant types based on the material type and performance requirements of their own products.
Consider flame retardant performance
Flame retardant efficiency is a core indicator. It is necessary to pay attention to the flame retardant level that the flame retardant can achieve for the material, such as V-0, V-1 and other levels in the UL94 standard. At the same time, the durability of the flame retardant should be considered. During the product life cycle, the flame retardant performance should not drop significantly due to environmental factors such as temperature and humidity changes. In addition, the compatibility of flame retardants with materials is also crucial. Poor compatibility may lead to problems such as decreased mechanical properties of materials and surface precipitation. Manufacturers can observe the flame retardant effect and physical property changes of materials after adding flame retardants through small sample tests.
Comply with regulations and environmental protection requirements
Different countries and regions have strict regulations on the use of flame retardants, such as the EU's RoHS Directive, REACH regulations, the United States' TSCA, and China's GB/T 24279. These regulations have clear restrictions on the content of harmful substances in flame retardants, such as polybrominated biphenyls and polybrominated diphenyl ethers. New manufacturers must ensure that the selected flame retardants meet the regulatory requirements of the target market to avoid market access problems due to environmental non-compliance. At the same time, as consumers' environmental awareness increases, choosing environmentally friendly flame retardants will also help improve the market competitiveness of products.
Balancing costs and benefits
While considering the performance of flame retardants, cost is also an important factor. It is necessary to comprehensively evaluate the unit price, addition amount and impact of flame retardants on production processes. Some high-performance environmentally friendly flame retardants may have a high unit price, but the addition amount is small and can reduce the subsequent processing cost, which is more cost-effective in the long run. Manufacturers need to combine product positioning and market demand, and choose the most cost-effective flame retardant on the premise of meeting flame retardant performance and environmental protection requirements.
Conclusion:
When novice manufacturers choose flame retardants, they need to comprehensively consider factors such as flame retardant types, performance, regulations and costs. Through in-depth understanding of product characteristics and market requirements, combined with sample testing and professional advice from suppliers, scientific and reasonable choices can be made to lay the foundation for product safety performance and market competitiveness.
