Understand flame retardants
Flame retardant is also known as flame retardant, fire retardant or fire retardant. Flame retardant is a functional additive that endows flammable polymers with flame retardancy, which is mainly designed for the flame retardancy of polymer materials. At present, the development of flame retardant materials is mainly achieved by adding flame retardant to the material matrix, which requires flame retardant, smoke suppression, self-extinguishing and drip resistance. Flame retardant is the key to the flame retardancy of polymer materials. After years of development, it has become an important additive for polymers.
Halogenation-free and environmental protection
With the enhancement of global awareness of environmental protection, halogen-free flame retardants have gradually become the focus of research. This kind of flame retardant not only reduces the release of toxic substances, but also meets the requirements of international environmental protection regulations. For example, phosphorus-based and nitrogen-based flame retardants are favored because of their low toxicity and low smoke characteristics, and have replaced traditional halogen-based flame retardants in many applications.
High performance and multifunction
The future flame retardant will develop in the direction of high performance and multifunction. This includes compound synergistic technology, superfine, nanometer technology and high-efficiency surface chemical modification technology. These technologies can improve the flame retardant efficiency and reduce the impact on the properties of materials.
New materials and modification technology
The progress of science and technology promotes the development of new flame retardant materials and production technology. For example, BDP flame retardant has excellent hydrolytic stability, low volatility and high thermal stability, and is suitable for engineering resins. In addition, the study of cage flame retardant also shows its potential in recycling and durability.
DCF series products are a new type of environmentally friendly flame retardant designed for silicone rubber.
This product can generate a carbon layer or a ceramic hard shell to cover the surface of the material under flame burning or high temperature, so as to isolate oxygen and heat, and it does not melt or drip, and has a very good heat insulation and flame retardant effect; Moreover, the product is treated by special auxiliary agent activation process, which has good compatibility with silicone rubber and plays a reinforcing role in silicone rubber; Green and nontoxic.
The whiteness is high, which has no influence on the color of the product;
The flame-retardant reinforcement effect is good. This product accounts for 40% ~ 60% of the finished product, which can reach the flame-retardant V-0(UL-94) level, and at the same time, the mechanical properties, especially the tear strength, are greatly improved. This product is environmentally friendly and nontoxic.
According to customers' different application scenarios, the products' respective flame-retardant effects (shell formation, charcoal formation and porcelain formation) can be used to meet customers' needs, so as to realize customized products for each customer.
Application of DCF series products
Mainly used in rubber and plastic rubber, silicone matrix, fireproof materials, new energy fireproof protection and high-tech materials.
