AMS3334 Silicone Sheeting & Uncured Compounds
ElastaPro’s AMS 3334 silicone sheeting is a premium, extreme low-temperature solid elastomer engineered specifically for critical aerospace, defense, and industrial sealing applications.
This 40 durometer (Shore A) material is formulated using advanced PVMQ (Phenyl Silicone) chemistry, allowing it to maintain flexibility, elastic recovery, and sealing integrity in environments where standard silicones brittle and fail.
Fully compliant with SAE Aerospace Material Specifications, our material meets or exceeds the strict testing parameters required for high-altitude flight components, cryogenic seals, and military-grade gaskets.
Why Choose ElastaPro for AMS 3334 Compliance?
Aerospace Grade Certification: Full certification data provided with shipments to verify compliance with the latest AMS 3334G standards.
Exceptional Low-Temperature Elasticity: Engineered to withstand service temperatures down to -130°F (-90°C) without cracking.
Flexible Custom Formats: Available in continuous roll sheeting, slit-to-width strips, or uncured compound for custom molding.

Common Applications and Industry Uses
Because AMS 3334 maintains its sealing performance under volatile thermal cycles, it is extensively specified across the commercial aviation, defense aerospace, and space exploration supply chains. Common configurations include:
High-Altitude Aircraft Seals: Door, window, and hatch gaskets exposed to sub-zero atmospheric flight conditions.
Environmental Control Systems (ECS): Ducting seals and insulation blankets managing extreme temperature differentials.
Cryogenic Sealing Components: Liquid gas handling equipment and low-temperature storage gaskets.
Vibration Isolation Mounts: Dampening pads for sensitive avionics and radar arrays operating in cold climates.
Frequently Asked Questions About AMS 3334
What is the difference between AMS 3334, AMS 3335, and AMS 3336?
While all three specifications govern extreme low-temperature PVMQ silicone sheeting, the primary differentiator is material hardness (durometer). AMS 3334 covers 40 Durometer (softer, more compressible), AMS 3335 covers 50 Durometer, and AMS 3336 covers 60 Durometer (firmer, higher tensile strength).
Does ElastaPro supply material certified to the latest AMS 3334G revision?
Yes. Our manufacturing and quality control standards align directly with the active SAE International aerospace revisions. Complete material certification and test reports are available upon request with your order.
What thicknesses and widths are available for continuous rolls?
We manufacture solid silicone sheeting in standard thicknesses ranging from 0.010″ up to 0.500″, with standard roll widths of 36″ and 48″. Custom slitting is available for narrow-strip gasketing needs.
