AMS3195 Silicone Properties

Key characteristics of AMS 3195 silicone:

  • Density: Medium firmness, with typical density around 32-43 pcf (550-690 kg/m³) depending on thickness.
  • Temperature Range: Typically rated for continuous service from -76°F to +450°F (-60°C to +232°C), with some formulations lasting up to +550°F intermittently.
  • Compression Deflection: 6-14 psi (41-97 kPa), making it easy to compress for seal integrity.
  • Compression Set: Good resistance, typically 60% after 22 hours at 100°C (212°F).
  • Tensile Strength: Approximately 125 psi (862 kPa).
  • Water Absorption: Low, often specified as 5%.
  • Appearance: Usually red or orange with a fabric finish on both sides.
  • Chemical Resistance: Excellent resistance to ozone, weathering, and UV.

FAQs about AMS 3195 Silicone

What is AMS 3195 silicone used for in aerospace applications

AMS 3195 silicone is a high‑temperature, low‑compression‑set elastomer used for molded seals, gaskets, and vibration‑damping components in aircraft and defense systems. Engineers specify it for applications requiring long‑term flexibility, thermal stability, and resistance to environmental exposure.

How does AMS 3195 differ from AMS 330X silicone sheet materials

AMS 3195 covers molded silicone rubber, while AMS 3302, AMS 3303, AMS 3304, and AMS 3305 cover solid silicone sheet and extruded profiles. AMS 3195 is typically used for molded O‑rings, custom shapes, and precision components, whereas AMS 330X materials are used for sheet‑based gaskets and fabricated seals.

What temperature range does AMS 3195 silicone support

AMS 3195 silicone generally operates from –65°F to +400°F (–54°C to +204°C), depending on formulation. This makes it suitable for engine‑adjacent components, ECS systems, and high‑altitude environments where thermal cycling is severe.

Is AMS 3195 silicone compatible with aviation fuels or hydraulic fluids

Standard AMS 3195 silicone is not fuel‑resistant. For exposure to Jet‑A, JP‑8, Skydrol, or petroleum‑based fluids, engineers should specify fluorosilicone (e.g., AMS‑R‑25988 or AMS 3325, AMS 3326, or AMS 3327). AMS 3195 is best suited for dry environments, air systems, and thermal or vibration isolation.

Can AMS 3195 silicone be molded into custom aerospace components

Yes. AMS 3195 is specifically designed for compression molding, transfer molding, and injection molding. It can be formed into O‑rings, seals, vibration isolators, thermal pads, and complex geometries that require tight tolerances and repeatable performance.
