Wedge IAC-300™ Fire Resistant Intumescent Aerogel Composite Fabric
FAQs - Wedge IAC-300™
1) What is Wedge IAC-300™?
Wedge IAC-300™ is a 3 mm intumescent aerogel composite fabric that combines a silica-aerogel insulation core with high-temperature face fabric and targeted intumescent seam technology for 120-minute fire-resistant jacket panels and thermal shields.2) Can 3 mm really achieve 120 minutes of protection?
Yes—when garments are built to the Wedge seam-map, with intumescent tapes at stitches, zips, cuffs and hems, controlled stitch density, and tested to the specified heat-flux/time profile. We provide a certification pathway and QA checklist.3) What temperatures can it handle?
Panels are engineered to tolerate ~1400 °C hot-face exposure (short-term incident heat) while keeping the protected side < 50 °C under defined test conditions. Continuous service temperature for the material class is −50 °C to 650 °C.4) What are typical applications?
Fire-resistant jackets/overcoats, hot-work PPE, proximity-style shields, emergency covers/blankets, EV fire-watch apparel, refinery and steel-plant maintenance.5) What is the exact construction?
Outer silica/AR glass face, 3.0 mm silica-aerogel core, intumescent strips/tapes placed under seam allowances and closures, and an FR viscose/para-aramid liner. Intumescent components are strategically placed, not full-area.6) What are the standard sizes and supply form?
Width 1.20 m; roll lengths 10 m or 20 m. Nominal thickness 3.0 mm (±0.5 mm). Basis weight typically 700–900 g/m² (face/liner dependent).7) Do you offer variants?
Yes: IAC-300-120FR-S (standard face), -AF (aluminized hot face), -BL (black liner), and -K (kit with pre-cut intumescent seam tapes).8) What certifications are relevant?
Material/panel: ASTM C177/C518 (λ), EN 13501-1, ASTM E84, and bench intumescence. Garments (market-dependent): ISO 11612 (A1/B/C), ISO 9151, ISO 6942, and EN 469 for firefighter ensembles. Wedge India manages lab coordination.9) How should OEMs cut and sew this fabric?
Use rotary/ultrasonic cutting with a vacuum table for accuracy. Apply a high-temp edge-seal on raw cuts to control dust/fibres. Sew with FR meta/para-aramid threads/tapes and avoid thermal bridges via stitch-density control and staggered quilting.10) How are intumescent elements integrated?
Install Wedge INTU-tapes (20–40 mm) beneath seam allowances, zipper guards, cuffs and hem tunnels per the Wedge seam-map. These activate around 180–200 °C and can expand ~20:1 to seal leak paths.11) Can I use my existing jacket pattern?
Often yes. We’ll review your pattern to adjust quilting, seam placements and hardware shielding. Minor changes usually unlock the 120-minute target without redesigning the entire garment.12) Is the fabric washable?
Prefer spot-cleaning/wipe-down. Industrial laundering may reduce aerogel loft and compromise edge seals. Request our care guideline if laundering is required.13) Is it safe and compliant (RoHS/halogen-free/asbestos-free)?
Yes—mineral insulation, non-halogen intumescent, asbestos-free, and RoHS-compatible. Follow normal fabrication PPE: P2/P3 mask, gloves and safety glasses during cutting/abrasion.14) What’s the minimum order quantity (MOQ) and lead time?
Typical MOQ is 2 rolls (can vary by finish). Standard finishes ship faster; -AF / -BL / -K variants may require additional lead time. Ask for current availability.15) Do you provide samples or cut panels?
Yes—A4 swatches, A3 test panels, and pre-cut pilot kits for approved OEMs. We can also supply jacket panel sets for lab testing.16) Can I get an aluminized hot face for radiant heat?
Choose variant IAC-300-120FR-AF. The aluminized film improves radiant reflectivity; we’ll advise on edge finishing and seam treatments.17) What documentation will I receive?
Technical Datasheet (PDS), MSDS/Safety note, Seam-Map & Sewing SOP, QA checklist, and a recommended test plan (ISO/ASTM) for your end use.18) Do you offer manufacturing collaboration/support in India?
Yes—Wedge India supports OEM onboarding, training, certification management, marketing, and pilot production to accelerate time-to-market.
