Equivalent to the environmental protection and safety of Fyrolflex RDP?
The so-called Fyrolflex RDP is actually an organophosphorus flame retardant, which is often used in the modification of plastics, rubber and related materials. Today, with the progress of science and technology, the concept of environmental protection is becoming more and more prosperous. Many chemical companies pursue green development and have developed environmentally friendly flame retardant products equivalent to Fyrolflex RDP. In terms of its environmental protection and safety performance, it covers the following numbers.
First, the original Fyrolflex RDP mainly contains phosphorus as an active ingredient, which can form a protective carbon layer on the surface of the material during combustion to reduce harmful flue gas and gas volatilization. New environmentally friendly equivalents also follow this principle, selecting raw materials to control the generation of harmful by-products in the production process. In addition, most modern alternatives do not contain heavy metals, halogens and other ingredients. Although they can decompose at high temperature, the decomposition releases are relatively mild and not easy to cause ecological and environmental pollution.
Second, in terms of human health and safety, Fyrolflex RDP and its equivalents are all low-toxic chemicals. Under reasonable process and use specifications, there is no significant acute harm to human skin contact or inhalation through the respiratory tract. New environmentally friendly alternatives pay more attention to the control of trace precipitates. When used in daily necessities, the fugibility is extremely low and the safety performance is particularly excellent. However, under high temperature combustion, volatile organic compounds must still be prevented to avoid accumulation in closed spaces.
Third, taking into account the recovery and degradation performance, the molecular structure design of environmentally friendly equivalent products is easier to be degraded by microorganisms or the natural environment. In the waste disposal process, the risk of releasing harmful substances is greatly reduced, which is beneficial to the ecological cycle. Some high-end products are prepared with bio-based materials, and the environmental compatibility is better.
However, to evaluate the environmental protection and safety of a product, it is still necessary to clarify the specific application scenarios and composite formulas. The raw materials are pure and the process is appropriate, and Fyrolflex RDP and its green alternatives can achieve the purpose of safety and environmental protection. However, in large-scale applications, it is still necessary to continuously study the environmental impact of its whole life cycle to ensure that it is not vulnerable to universal use. In addition, we should abide by laws and regulations, choose materials carefully, and be careful about chemical circulation and waste management, so as to achieve both safety and environmental protection.

What is the recommended amount of Fyrolflex RDP in the recipe?
Fyrolflex RDP is also known as Resorcinol bis (diphenyl phosphate) (RDP). It is a commonly used organophosphorus flame retardant and is widely used in the formulation of various polymer materials, especially epoxy resin, polycarbonate, ABS, polyphenyl ether, polyurethane, etc. Its main function is to endow the material with excellent flame retardancy, and it can both plasticize and improve processing performance. However, the recommended addition amount in the formula is not 100%, and it needs to be comprehensively weighed according to the matrix resin, target flame retardant grade and the compatibility of other additives.
Where Fyrolflex RDP is used as the main flame retardant agent, the dosage in general engineering plastics is mostly between 10% and 25% of the total material. If UL-94 V-0 grade is the target, it often needs to be added to 15% to 20% to cope with severe tests. If only V-1 and V-2 grades are pursued, the relative discretion can be reduced. However, the specific amount must be considered in combination with the oxygen index, thermal decomposition behavior, mechanical strength and other factors of the material itself. If combined with a little synergistic flame retardant (such as antimony trioxide, metal hydroxide, nitrogen-based additives), the amount added to the main system can also be appropriately reduced without losing its effectiveness.
RDP is liquid and evenly dispersed in the formula. However, if it is excessive, there is a risk of exudation and precipitation, and the mechanical and electrical properties of the material may be degraded, so the dosage still needs to be moderately controlled. Also pay attention to its resistance to migration and compatibility, so as not to cause dust to adhere to the surface of the material due to excessive addition, or affect the subsequent processing and product molding quality.
In short, the recommended dosage of Fyrolflex RDP is adjusted according to the application scenario, and the cycle test is carried out to find the best balance point. The commonly used starting amount may be added to the target amount step by step from 12%, and the flame retardant effect and the comprehensive performance of the product should be reviewed to determine. In this way, the formula can not only have excellent flame retardancy, but also the reliability of physical properties.
