Two Component Silicone For Reusable Vacuum Bags

설명

Core Product: Reusable Silicone Vacuum Bags
Ideal For: RTM, Resin Infusion, Vacuum Bagging (Aerospace, Automotive, 3D-Printed Composites, GRC/GRG/GFRC)

Key Advantages vs. Plastic Bags

• Sustainability:♻️ Replaces 200+ plastic bags, cuts waste by 90%, fully recyclable, 50% lower CO₂ footprint.
• Durability:200+ cycles vs. plastic’s 1-2 cycles.
• Cost Savings:⬇️ 70% lower consumable costs, reduces labor & disposal fees (See Annual Cost-Benefit Table).
• Performance:Withstands -50°C to 230°C (ideal for prepreg/HT resins), superior airtight seal on complex molds.
• Convenience:Dishwasher-safe, easy cleaning, self-releasing from molds.

⚙️ Technical Specifications (Topsil  Silicone Rubber)

• Tensile Strength:8-10 MPa
• Tear Resistance:25-30 N/mm
• Viscosity:10,000 mPa·s (low flow, precise replication)
• Certifications:FDA-compliant (Food Grade), RoHS, REACH
• Customizable:1mm to 10mm thickness, any size/complexity.

✅ Applications & Compatibility

• Processes:RTM, Resin Infusion, Vacuum Debulking, Prepreg Curing.
• Materials:Epoxy, Carbon Fiber, Fiberglass, RTM resins.

Operation Method (Spraying/Brushing)

1. Prep mold tool (flange runners, vacuum channels).
2. Spray/silicone onto mold.
3. Apply peripheral silicone flange seal.
4. Reinforce with cloth; add metal inserts.
5. Cure in 20 mins.
6. Self-releasing bag easily removed.
7. Proceed with gel coat, reinforcement (glass/carbon + cores), flow mesh.
8. Position silicone bag, connect vacuum & resin lines
9. Infuse resin, cure part.
10. Reuse bag (~200x).
