Specification Grade Silicones

Douglas Material Specifications (DMS) Silicone Sheet & Uncured Compound

ElastaPro manufactures aerospace-grade solid silicone sheeting and uncured silicone compounds engineered to meet rigorous Douglas Material Specifications (DMS). Originally established by the Douglas Aircraft Company and maintained under Boeing’s strict quality management systems, DMS silicones are vital for high-reliability components in commercial aviation, defense, and aerospace applications.

We deliver consistent, high-performance elastomer solutions that withstand high-altitude flight, extreme thermal cycling, and harsh environmental exposure.

Frequently Asked Questions about DMS Silicones

What are DMS silicones, and which specifications does ElastaPro manufacture?

DMS (Douglas Material Specifications) silicones are high-performance elastomer formulations originally developed by the Douglas Aircraft Company and maintained under Boeing’s quality management systems. ElastaPro manufactures a wide range of DMS-compliant solid silicone sheets and uncured compounds at our AS9100D and ISO 9001:2015 certified facility in Santa Fe Springs, California. Our capabilities include:

  • General Purpose & Specialty VMQ: DMS 1522, 1530 (High-Temp), 1531 (Low-Temp), 1533, 1535 (High-Strength), 1536 (Flame-Resistant), 1537 (Electrically Conductive), 1539 (Low Compression Set), and DMS 2221.

  • Fuel-Resistant Fluorosilicones (FVMQ): DMS 1937, 1939, and 1940 (engineered for jet fuel, oil, and solvent resistance).

  • Advanced Compounds: DMS 2304, 2306, 2307, 2308, and 2310 for thermal, conductive, EMI shielding, and vibration-damping needs.

Are ElastaPro DMS silicones available as fully cured sheets or uncured compounds?

ElastaPro offers flexible product options depending on your fabrication requirements:

  • Cured Solid Silicone Sheeting: Supplied in continuous rolls with thicknesses ranging from 0.010″ to 0.500″ and standard widths of 36″ and 48″ (custom widths available). Ideal for die-cutting into aerospace gaskets and seals.

  • Uncured Silicone Compounds: Packaged as continuous slabs or sheets, ready for compression, transfer, or injection molding by component manufacturers.

How do DMS fluorosilicone grades (such as DMS 1940) differ from standard DMS silicone sheets?

While standard silicone (VMQ) offers superior high/low-temperature stability, low compression set, and weather resistance, fluorosilicone (FVMQ) grades—such as DMS 1937, 1939, and 1940—are specifically formulated for environments where the material comes into contact with aerospace fluids. Fluorosilicones combine the extreme temperature performance of silicone with enhanced chemical resistance against jet fuels, synthetic oils, hydraulic fluids, and solvents.
