Page views:In high-end manufacturing fields such as electronic appliances, automotive lightweighting, and medical devices, thin polycarbonate (PC) plastics have become indispensable key materials due to their excellent light transmittance, impact resistance, and processing fluidity. However, the flame retardant treatment of traditional thin PC plastics has long faced an industry pain point where "safety" and "performance" are difficult to balance - halogen-containing flame retardants have high flame retardant efficiency, but they release toxic and harmful gases when burned, posing serious threats to the environment and human health; some flame retardant solutions significantly sacrifice the mechanical properties and light transmittance of thin PC plastics. Against this backdrop, the halogen-free and fluorine-free flame retardant for thin polycarbonate plastics developed by Inovia Materials LLC undoubtedly brings a technological innovation that balances safety and performance to the industry.
Industry Pain Point: The "Dilemma" of Flame Retardancy for Thin PC Plastics
The application scenarios of thin polycarbonate plastics have strict requirements on material performance. Taking 5G communication equipment casings and ultra-thin laptop bodies as examples, the material not only needs to have an ultra-thin thickness of 0.5-2mm but also needs to balance drop resistance, light transmittance, high-temperature resistance and other characteristics. Traditional flame retardant technologies often fall into multiple dilemmas when meeting these requirements:
Environmental safety hazards: Halogen-containing flame retardants release corrosive gases such as hydrogen chloride and hydrogen bromide when burned at high temperatures, which not only corrode electronic components but also cause harm to the human respiratory tract. Moreover, waste materials are difficult to degrade naturally, failing to meet environmental standards such as EU RoHS and China's GB/T 26125.
Performance loss problem: Some halogen-free flame retardants (such as traditional phosphorus-based ones) require a high addition amount to achieve flame retardant effects, resulting in a 15%-30% decrease in the impact strength of thin PC plastics and a more than 20% reduction in light transmittance, which cannot meet the appearance and structural requirements of high-end products.
Poor processing stability:The molding temperature of thin PC plastics is usually 260-300℃, and some flame retardants are easy to decompose and precipitate at high temperatures, leading to surface defects of products and shortening the service life of processing equipment.
Technological Breakthrough: Core Advantages of Inovia's Halogen-Free and Fluorine-Free Flame Retardant
This flame retardant developed by Inovia Materials LLC fundamentally solves the pain points of traditional technologies through molecular structure design and collaborative flame retardant mechanism innovation, and its core advantages are reflected in the following three aspects:
1. Ultimate Environmental Protection: Halogen-Free and Fluorine-Free, Safe Throughout the Life Cycle
The flame retardant is completely free of halogens (chlorine, bromine) and fluorine elements. When burned, it only releases carbon dioxide and water, without producing toxic gases and corrosive substances. Verified by third-party testing institutions, its smoke toxicity level reaches ZA1 level (minimum toxicity) in GB/T 20284-2006, and it complies with all restrictions on Substances of Very High Concern (SVHC) in the EU REACH regulation. For enterprises pursuing green production, using this flame retardant can directly avoid environmental compliance risks and enhance the market competitiveness of products.
2. Performance Balance: Low Addition Amount, Balancing Multi-Dimensional Indicators
Relying on nano-dispersion technology and flame retardant synergistic system, the addition amount of this flame retardant only needs 3%-5% (traditional halogen-free flame retardants require 8%-12%) to make thin PC plastics reach the UL94 V-0 flame retardant standard (1.6mm thickness). At the same time, it has minimal impact on the mechanical properties and optical properties of the material:
The retention rate of impact strength exceeds 90%, meeting the drop resistance requirements of ultra-thin products;
The light transmittance (400-800nm) is maintained above 88%, basically the same as pure PC plastics, suitable for scenarios such as transparent casings and optical components;
The heat distortion temperature (HDT) is increased by 5-8℃, enhancing the stability of products in high-temperature environments.
3. Processing Friendliness: High-Temperature Stability, Adapting to Existing Production Lines
The thermal decomposition temperature of this flame retardant is as high as 320℃ or above, far exceeding the processing temperature range of thin PC plastics. During extrusion and injection molding
