Flame-Retardant Silicone Materials for Custom Parts
Review flame-retardant silicone material options for custom parts that require fire performance, electrical protection, heat resistance, and stable molding support.
Built for Safer Silicone Components
Flame-retardant silicone is selected when your part must combine silicone flexibility with improved fire performance, electrical protection, heat resistance, and stable processing. It is suitable for projects where material behavior under flame exposure must be reviewed early.
- Supports flame-retardant performance review for electrical, energy, lighting, and industrial protection parts.
- Available HCR reference families include V-0 directions at 1 mm or 2 mm in supplier data.
- Material choice can be reviewed with hardness, wall thickness, molding route, and certification requirements before sampling.
Reference Performance Ranges
This table uses confirmed supplier-table directions. Final material approval should still depend on finished-part thickness, color, curing route, flame test scope, and required certification documents.
| Material Direction | Reference Series | Hardness Range in Table | Tensile Strength | Elongation | Tear Strength | Flame / Processing Notes |
|---|---|---|---|---|---|---|
| Flame-Retardant HCR | TY26E9 series | Shore A 70–72 | Approx. 4.5–7.5 MPa | Approx. 250–600% | Approx. 17–30 N/mm | V-0 at 1 mm directionUL yellow card directionGrade-specific confirmation required |
| Flame-Retardant HCR | TY2961 series | Shore A 70–72 | Approx. 4.5–7.5 MPa | Approx. 250–600% | Approx. 17–30 N/mm | V-0 at 2 mm directionGood processing directionMolded parts review |

Note: Flame-retardant performance is affected by material grade, wall thickness, pigment, molding process, post-curing, part geometry, and the actual test standard. Final approval should be based on grade-specific data and finished-part testing.
FR Material Support Backed by Factory Execution
Beyond flame-rating data, your project needs material selection, molding route review, controlled production, and complete documentation support.
Dedicated Formulation Development
Exclusive material formulas can be reviewed around target flame performance, hardness, color, molding route, and finished-part requirements.
Premium Silicone Raw Material Source
FR silicone projects are supported by premium silicone raw materials from major suppliers, helping deliver strong performance and stable material quality.
Controlled Production Capacity
Strong manufacturing capability, controlled production environment, and repeat-order process control help maintain consistent silicone part quality across batches.
Complete Documents & Certification Support
Material reports, batch records, inspection files, flame-retardant documentation, and third-party testing coordination can be prepared according to your market needs.
Need to confirm V-0 direction, thickness, or document scope?
Send your drawing, wall thickness, application, color requirement, and target standard. We can review material route and testing needs before sampling.
Flame-Retardant Product Cases
These case directions show where flame-retardant silicone may be considered. The final material route should still be confirmed by drawing, wall thickness, flame-rating target, and expected use condition.
Electronics Protection Parts
For covers, pads, insulation components, and soft electrical protection parts.
LED & Lighting Seals
For silicone seals and protective structures near heat or electrical assemblies.
Connector Covers
For molded silicone covers, boots, and insulation structures.
FR Gaskets & Pads
For protective gaskets, pads, and molded parts requiring fire-performance review.
Energy & Charging Parts
For protective silicone components used around electrical and energy systems.
Manufacturing Routes for Flame-Retardant Silicone Materials
Your FR silicone project needs a process route that protects wall thickness, material dispersion, molding stability, and finished-part consistency from sampling to repeat production.
HCR Compression Molding
You can use HCR molding for FR silicone parts where wall thickness, mold temperature, pressure, and post-curing need early review.
LSR Injection Review
You can review LSR molding feasibility when the selected FR material, part geometry, flow behavior, and testing scope are clear.
Transfer Molding
You can choose transfer molding when FR silicone parts include detailed structures, insert areas, or cavity filling requirements.
Extrusion
You can produce FR silicone strips, sleeves, profiles, and protective sections where continuous shape control is important.
Finishing & Post-Processing
You can plan trimming, deflashing, surface finishing, color review, inspection, and packaging based on FR part requirements.
Material & Mold Evaluation
You can review material choice with wall thickness, gate design, parting line, tolerance, mold release, and flame-rating target before sampling.
What Helps Confirm Your FR Material Route
Complete project information helps determine whether a V-0 at 1 mm direction, V-0 at 2 mm direction, or another flame-retardant silicone route is suitable before sampling.
Need to Confirm a Flame-Retardant Silicone Route?
Send the drawing, target rating, test thickness, product use, working environment, estimated quantity, and sample photos. Your FR material and process options can then be reviewed before sampling.
