Flame-Retardant Silicone：Applications & Testing Standards
【Applications of Flame-Retardant Silicone】
1. Electronics & Electrical Industry
Applications: Insulation layers for cables, connector seals, circuit board protective coatings.
Advantages: Prevents fire hazards caused by short circuits while offering excellent insulation properties.
2. Construction Industry
Applications: Fireproof sealants, window and door seals, building joint fillers.
Advantages: Delays flame spread in fires, reducing smoke and toxic gas emissions.
3. Automotive Industry
Applications: Engine compartment seals, battery insulation materials, wire harness protective sleeves.
Advantages: High-temperature resistance, oil resistance, and aging resistance, meeting automotive flame-retardant safety standards.
4. Aerospace Industry
Applications: Aircraft cable insulation, cabin seals, thermal insulation materials.
Advantages: Maintains stable flame-retardant and mechanical properties even in extreme environments.
5. Household Appliances
Applications: Sealing rings for heaters, oven door gaskets, wire sheathing.
Advantages: Prevents fire hazards caused by overheating appliances.
【Flame-Retardant Silicone Performance Testing Standards】
1. UL94 Flame-Retardant Rating
Evaluates flammability of materials, categorized into V-0, V-1, and V-2 ratings.
V-0 is the highest level of flame resistance.
2. LOI (Limiting Oxygen Index) Test
Measures how easily a material burns in an oxygen-rich environment.
The higher the LOI value, the better the flame-retardant performance.
3. Smoke Density Test
Assesses the amount of smoke produced during combustion.
Low-smoke materials are considered safer.
4. Toxicity Test
Detects toxic gases released during combustion to ensure compliance with environmental and safety standards.
