Maximize Flame Retardance in
Filled and Unfilled Polymer Systems
Facing concerns and regulations about the toxicity of halogenated additives,
manufacturers and compounders are turning to halogen-free flame retardants
(HFFRs). Silicone-based HFFR technologies from Dow Corning provide a low
rate of heat release and toxic gas evolution and excellent smoke suppression,
while maintaining the resin's or compound's mechanical properties.
Our silicone FR additives target common scenarios:
- They act as a synergist in highly filled systems. Through effective
dispersion, these additives enhance the performance of FR fillers such as
aluminum hydroxide (ATH) and magnesium hydroxide (MDH). This strategy
compensates for limitations in the amount of FR fillers that can be
incorporated without degrading mechanical performance.
- They provide high FR performance in unfilled systems. For example, Dow
Corning offers a unique FR additive for clear PC.
Solving Your Processing
Dow Corning HFFR technologies are ideal for highly filled compounds
used for wire & cable insulation, window profiles and pipes. In clear
polycarbonate applications such as LED lighting, automotive windows and gauges
and aircraft components, our patented
Dow Corning® 40-001
Additive (PDF) enhances
anti-dripping performance and reduces flaming time. It offers lower haze
compared to KSS and PTFE formulations, and has no impact on tensile modulus and
tensile strength at traction when used at loadings up to 2 wt%.
Dow Corning draws on 20 years of FR experience to provide high
flame-smoke-toxicity performance while maintaining or improving mechanical and
aesthetic properties. Other benefits of our portfolio include:
Effective at low loadings (2 wt% to 4 wt%)
Proven synergies with other FR additives
