Silicone Foam Low Density SM150-FG1
SM150 is a low-density silicone foam / solid gasket material made from ceramifiable silicone rubber. At room temperature, it retains the elasticity, sealing capability, and processability associated with silicone rubber; when exposed to high-temperature flames or extreme overheating, its special additives react with the silicone matrix and form a rigid, porous ceramic-like shell. This gives the material combined functions in sealing, electrical insulation, thermal insulation, flame retardancy, and fire-barrier protection.

Informations techniques
Review the product positioning, technical data, sealing and insulation behavior, application fit, and handling guidance for SM150 low-density silicone foam.
Q1
What is SM150 positioned for within Silicone Foam Low Density?
Based on your confirmation and the uploaded TDS, SM150 should be treated as the low-density page’s corresponding model, with emphasis on sealing, electrical insulation, thermal insulation, and fire-barrier conversion under high temperatures.
Ceramifiable Silicone Direction
At room temperature it behaves like a processable silicone gasket; at high temperature it converts into a hard ceramic-like shell.
Sealing + Fire Barrier Use
Suitable where sealing function and fire-protection / thermal-barrier behavior must be combined in one material.
Electrical Insulation Support
Provides high electrical insulation capability for protected enclosure or battery-related structures.
Low-Density Page Fit
This page now combines the Low Density category position with the specific SM150 technical configuration you confirmed.
Q2
What are the key technical data for SM150?
The uploaded TDS provides the following core values for model selection, sample evaluation, and project discussion.
| Propriété | Norme d'essai | SM150 |
|---|---|---|
| Couleur | Visuel | Blanc |
| Épaisseur (mm) | / | 0.3 ± 0.03 |
| Density (kg/m³) | ASTM D3574-95 | 1500 ± 30 |
| Résistivité volumique | JIS C 1302 | >1×1014 Ω-cm |
| Rigidité diélectrique | ASTM D149 | >5.0 kV |
| Conductivité thermique | ASTM D5470 | <0.3 W/(m·K) |
| Dielectric Constant | JIS C 1302 | 3.5 |
| Flame Retardancy | UL94 | V0 |
| Résistance à la traction | ASTM D412 | 1.7 MPa |
| Tear Performance | ASTM D412 | 70 |
These values are suitable for early-stage technical screening and project communication. Final suitability should still be verified under the user’s real sealing, thermal, and fire-protection conditions.
Q3
What functional strengths does SM150 emphasize?
The TDS focuses on thermal insulation, electrical insulation, tear resistance, and high-temperature ceramic conversion for fire protection.
High-Temperature Ceramic Conversion
Under high temperatures, the material transforms into a rigid ceramic body, helping provide a continuous thermal barrier.
Exceptional Thermal Insulation
Low thermal conductivity helps reduce heat transfer across protected interfaces.
Isolation électrique
High volume resistivity and dielectric strength support insulated sealing and barrier structures.
Excellent Tear Resistance
Useful where the converted gasket must maintain integrity during handling and installation.
