- EC Number
- 601-699-0
- Chemical Name
- Zinc Stannate
Flamtard S (zinc stannate) is an insoluble, non-hazardous, antimony-free flame retardant synergist, and is increasingly being used in green applications, particularly in the electronics industry. It is extremely effective in PVC systems for cable sheathing, epoxy resins for printed circuit boards, polyamides and surface coatings. Flamtard S is thermally stable up to 400 °C; at higher temperatures (400 °C - 600 °C) zinc and tin ions exert catalytic activity that inhibits the radical chain reaction causing the flame.

- Challenges
The miniaturization of electronic components and electrical devices presents an innovation challenge because higher levels of performance are required for moldings of increasingly thinner sections. For example, improving flame and smoke inhibition in complex components by incorporation of additives and reinforcing agents is counter intuitive to improving the flaw properties of the polymer compound, which is required to fill intricate molds. Regulatory demands create an additional level of complexity, because the additives employed to overcome the technical and practical challenges must do so without causing harm to health or to the environment. Challenges such as these create opportunities for highly active multi-functional polymer additives that have no harmful classifications like Flamtard.

- Market Segment
Polyamide 66 is has saveral properties that make it the material of choice for engineering applications; for example good mechanical and electrical properties at elevated temperatures, chemical resistance and wear & friction behavior. Applications in the electrical and electronics sector have non-flammability as a critical performance parameter; which must be achieved without adversely affecting key properties like tensile strength, elongation and impact strength. The compatibility of polymer additives becomes even more important in reinforced systems, where the interactions can have significant effects on molding properties as well as compound strength.
