Flame Retardant Silicone Components
ARPL manufactures flame retardant silicone rubber components — gaskets, seals, covers, grommets, O-rings and custom molded parts formulated to meet UL 94 V-0 and V-1 flammability ratings. We support EV battery packs, electrical enclosures, charger housings, and industrial applications with FR HCR, FR LSR, sponge silicone and halogen-free grades. All FR compounds are available in RoHS and REACH compliant grades.
FR Silicone Component Types
We manufacture FR silicone components in all of the above categories with custom compound selection and specifications tailored to your flammability, temperature, and sealing requirements.
Flame Retardant Silicone Components for Fire Safety & Sealing
ARPL manufactures flame retardant silicone rubber components for applications where fire resistance, self-extinguishing behavior, and durable sealing are required. Our FR silicone parts are designed for EV battery packs, electrical enclosures, charger housings, and industrial equipment — anywhere that UL 94 V-0 or V-1 compliance is mandatory.
Flame retardant silicone maintains its sealing and insulating properties across a wide temperature range (-55°C to +200°C) while offering low smoke generation, low toxicity, and self-extinguishing behavior. Our engineering team works with your design data to select the right FR compound, optimize cross-section geometry, and validate flammability performance before tooling.

What We Optimize For
- UL 94 V-0 / V-1 compliance — compound and thickness validated for target rating
- Low smoke & low toxicity — minimal smoke and non-toxic combustion byproducts
- Self-extinguishing behavior — flame stops within 10 sec (V-0) or 30 sec (V-1)
- Stable sealing force — low compression set over -55°C to +200°C thermal cycling
- IP67/IP68 sealing — gasket geometry optimized for ingress protection with flame retardancy
FR Silicone Material Comparison

|---|---|---|---|---|---|
| FR HCR (VMQ) | -55 to +200°C | V-0 / V-1 | Robust gaskets, mechanical strength | Good vs. water, UV, ozone | Battery lid gaskets, enclosure seals |
| FR LSR | -55 to +200°C | V-0 / V-1 | Complex geometry, high volume | Good vs. water, UV | Connector seals, grommets, precision gaskets |
| FR Sponge | -55 to +200°C | HF-1 / V-0 | Low compression force sealing | Good vs. water, UV | Access panel gaskets, lid seals |
| Halogen-Free FR | -55 to +200°C | V-0 / V-1 | Zero halogen, low smoke | Good vs. water, UV, ozone | Rail, aerospace, IEC 61249 enclosures |
| FR FVMQ | -55 to +175°C | V-0 / V-1 | FR + fuel/oil resistance | Good vs. fuels, oils, coolants | Drivetrain seals, inverter seals |

Frequently Asked Questions
Find answers to common questions about flame retardant silicone components
Flame retardant silicone components are molded silicone rubber parts formulated with FR additives to resist ignition, self-extinguish, and meet UL 94 V-0 or V-1 flammability ratings. They are used as gaskets, seals, covers, grommets, O-rings and insulating interfaces in EV battery packs, electrical enclosures, charger housings, and industrial equipment where fire safety is mandatory.
ARPL manufactures FR silicone components in FR HCR Silicone (FR VMQ), FR Liquid Silicone Rubber (FR LSR), FR Sponge Silicone, Halogen-Free FR Silicone, and FR Fluorosilicone (FR FVMQ). Compound selection depends on your flammability target, temperature range, media exposure, and part geometry.
Yes. UL 94 V-0 means the material self-extinguishes within 10 seconds on a vertical specimen with no flaming drips. Material selection for V-0 performance depends on compound grade, part thickness, and test conditions. Share your compliance target and application details for a recommendation.
FR silicone components are used in EV battery packs, EV chargers, electrical switchgear, power electronics (inverters, OBC, PDU), solar inverters, rail transport (low smoke/low toxicity), aerospace (FAR 25.853), medical device enclosures, telecom cabinets, and industrial automation equipment.
FR HCR (solid silicone) offers robust mechanical strength and is suited for compression-molded gaskets and covers. FR LSR provides consistent shot-to-shot repeatability for complex geometries and high-volume injection molding. The best option depends on part geometry, tolerance needs, flammability target, and production volume.
Please share: 2D drawing or CAD, part thickness, operating temperature range, media exposure, target flammability rating (e.g. UL 94 V-0), IP rating if applicable, annual volume, and PPAP/validation expectations.
