The most cost-effective Sb2O3 substitute

RTP-50 is a new type, high-performance inorganic FR synergist. The advantage include low dosage, easy to use, little influence to products' mechanical properties, cost effective. It works through flame retardant elements such as silicon, magnesium, aluminium and calcium, no bromine or antimony contents are included.

Product advantages:

1. Reduce customer's production cost.

2. little of non-eco ingredients.

3. Reduction of product density.

4. Reduce the amount of titanium dioxide needed for light-colored products.

5. Shorten the process of injection molding.

6. Increase the heat distortion temperature of the final product.

Flame-retardant mechanism:

This product can play an acid catalysis effect during the combustion of polymers, making the whole system partially cross-linked and carbonized, thus forming a char protective layer, to prevent the release of volatile decomposition products. At the same time, RTP-50 can also reduce the decomposition temperature of antimony oxyhalide generated during the reaction between halogen flame retardants and Sb2O3, so as to achieve the purpose of assisting flame retardancy.

Features:

• Excellent high-temperature resistance and thermal stability. TGA is only 0.5‰wt within 400℃.
• Good compatibility with modified plastic products such as PA, PBT, PP, PET, ABS, PVC and PC+ABS alloy, therefore the mechanical properties of the final products can be well maintained.
• RTP-50 can replace Sb2O3 by 20%～40%wt, and at the same time no influence to the flame retardant performance. Thus saving much production costs.
• With no more than 3% addition of RTP-50, flowability of the plastic compound can can be significantly improved, thereby improving the dimensional stability and surface smoothness of the final product. RTP-50 can also help significantly improve the electrical properties (dielectrical strength and CTI) of the product.
• RTP50 can help maintain the mechanical and electrical properties of the product under high temperature and high humidity circumstances.

Conclusion:

• RTP-50 can partly replace Sb2O3 in the bromine-antimony based flame retardant modification of many plastic types.
• While reducing customer's production costs, it can also significantly improve the processability of materials. And can to some extent improve some of the mechanical properties of the modified plastic.
• With the fast development of modern society, requests and expectations on modified plastics continue to increase. And the continuous consumption of Metal mineral resources, which are non-renewable, their quantities are decreasing year by year due to increasing human consumption.
• RTP-50, as a new type additive, can help ease the consumption of precious mineral resources (antimony), and much more eco-friendly than antimony, thus worthy of customer welcome and acceptance.
