Specification Grade Silicones

BMS Silicone

BMS silicone from ElastaPro meets Boeing Material Specifications (BMS). Choose these specification grade silicone materials as solid silicone sheet or uncured silicone compound in the durometers, sizes, and colors that you need. ElastaPro is AS9100D and ISO 9001:2015 certified.

BMS Silicone Solid Sheet

BMS solid silicone sheets are engineered to meet stringent standards for flexibility, durability, and high resistance to environmental factors. This makes them suitable for diverse aircraft components. They are also utilized in gaskets, seals, and insulation applications, providing reliable performance in challenging aerospace environments.

At ElastaPro Silicone Sheeting, these sheets arrive ready for die-cutting. They are between 0.010” and 0.500” thick and available in widths of up to 60”.

BMS Silicone Uncured Compound

The BMS sets stringent standards for uncured silicone compounds’ right chemical composition and physical properties. This ensures that they meet the specific requirements for aerospace use. By adhering to BMS, manufacturers guarantee that the compounds contribute to producing high-quality and durable aviation components.

What are Boeing Material Specifications?

Boeing utilizes various specifications for silicone materials and compounds within its Boeing Material Specification (BMS) system. These specifications ensure silicones meet the demanding requirements of aerospace applications, including flexibility, durability, and resistance to environmental factors like high temperatures, chemicals, and ozone.

Why Does Boeing Have Its Own Specs?

Boeing, as a major aircraft manufacturer, has its own detailed specifications for its aircraft for several important reasons:

Ensuring Consistency and Safety: Boeing’s specifications are a comprehensive set of technical requirements, standards, and tolerances that ensure uniformity in design, manufacturing, and performance across their entire product line. These specifications contribute to maintaining a consistent level of safety and operational reliability in every aircraft they produce.

Managing Complex Manufacturing: The manufacturing of large, complex aircraft like those built by Boeing requires meticulous control over every aspect of the process, including the properties of materials, manufacturing processes, and final assembly. Boeing’s specifications provide the necessary level of detail to manage this complexity, minimize risks during assembly and maintenance, and ensure the overall quality and safety of their aircraft.

Meeting International Standards and Regulations: Boeing’s specifications are developed in consideration of international aviation safety standards and regulations established by organizations such as the FAA (Federal Aviation Administration) and EASA (European Union Aviation Safety Agency). This ensures that their aircraft can operate safely and legally in diverse operational environments around the world.

Customization and Innovation: While adhering to general aviation standards, Boeing’s internal specifications also allow for the incorporation of unique design features, advanced technologies, and customizations that differentiate their aircraft models and cater to specific customer requirements.

Proprietary Expertise and Continuous Improvement: Developing and maintaining their own specifications allows Boeing to leverage their extensive proprietary knowledge and expertise in aircraft design and manufacturing. These specifications are constantly reviewed and updated based on feedback from the field, technological advancements, and insights gained from operational data, ensuring continuous improvement in their products.
