In the field of transparent polycarbonate (PC) modification, flame retardants often face a difficult choice: sacrifice transparency for flame retardancy, or compromise efficient flame retardancy to meet environmental regulations. IOTA 61036 Silicone Flame Retardant completely breaks this dilemma. Based on a silanol-functional silicone resin, it helps transparent PC materials pass stringent UL94 V-0 flammability tests with almost no impact on transparency or haze. It contains no fluorine, phosphorus, bromine, or other elements, truly achieving a balance of high-efficiency flame retardancy, environmental friendliness, and optical clarity.
IOTA 61036 is a silanol-functional silicone resin specifically designed for transparent PC flame retardant systems. It effectively improves flame retardancy and anti-dripping performance while having almost no impact on PC transparency, making it an ideal choice for high-end transparent PC modification.
High-Efficiency Flame Retardancy: Enables transparent PC to achieve UL94 V-0 rating at 1.6–2.0 mm thickness
Excellent Transparency Retention: Almost no effect on PC light transmittance or haze
Environmentally Compliant: PFAS-FREE, contains no fluorine, phosphorus, bromine, or other elements
Solvent-Free Design: 100% active content, green and environmentally friendly
| Parameter | Value |
|---|---|
| Appearance | Colorless to slightly yellow transparent liquid |
| Content | ≥99.5% |
| System | Recommended Addition Level | Synergistic Flame Retardant | Achievable Flame Retardancy Rating |
|---|---|---|---|
| Transparent PC Flame Retardancy | 1–4% (by weight) | Sulfonate (RM65 or KSS recommended) or phosphorus-silicone flame retardant (PSI-910) | 1.6–2.0 mm UL94 V-0 |
No Impact on Transparency: PC light transmittance and haze remain almost unchanged after addition
Significant Anti-Dripping Effect: Effectively suppresses molten drips during combustion, helping achieve V-0 rating
Good Synergistic Compatibility: Works better when combined with sulfonate or phosphorus-silicone flame retardants
Halogen-Free & Fluorine-Free: Contains no fluorine, phosphorus, bromine, or other elements – meets strict environmental regulations
| Dimension | Advantage |
|---|---|
| Performance | 1.6mm V-0 flame retardancy + high transparency + low haze |
| Environmental | PFAS-FREE, no fluorine, no phosphorus, no bromine |
| Processability | Liquid form, easy to disperse, low addition level |
| Compliance | Meets trends toward RoHS, REACH, and other environmental directives |
IOTA 61036 – Transparent PC flame retardancy without sacrificing clarity – truly “clear protection, safe and fearless.”
