Specification Grade Silicones

ASTM Silicone Solid Sheet and Uncured Silicone Compound

ASTM silicones from ElastaPro are specification grade silicone materials that meet specific standards from ASTM International. Choose solid silicone sheet or uncured silicone compound in the durometers, sizes, and colors that you need.

Solid Sheet

Materials arrive ready for die cutting and is between .010” to .500” thick and available in widths of up 60”.

Uncured Compound

Materials arrive ready for curing.

What are ASTM Silicones?

ASTM silicones meet standards set by ASTM International (formerly known as the American Society for Testing and Materials). These standards, particularly ASTM D2000, classify and specify the physical properties of silicone rubber, ensuring its suitability for various applications by outlining requirements for hardness, tensile strength, elongation, and resistance to temperature and chemicals.

What is ASTM D2000?

ASTM D2000 is a standardized system for rubber products, primarily used in the automotive industry, but also widely adopted by other sectors. It provides a way to specify and categorize rubber materials based on their properties, ensuring consistency and facilitating communication within the rubber industry.

Key Properties Defined by ASTM D2000

ASTM D2000 includes guidelines for:

Hardness:Measured using the Shore A durometer, indicating the material’s resistance to indentation.

Tensile Strength:The maximum stress the rubber can withstand before breaking when stretched.

Elongation:The extent to which the silicone rubber can be stretched before breaking.

Ensuring Quality and Performance

By adhering to ASTM standards, manufacturers can ensure that their silicone products meet specific performance benchmarks, making them suitable for demanding applications in industries like automotive, medical, and electrical. 

Other Relevant ASTM Standards

Besides ASTM D2000, other ASTM standards apply to specific silicone applications, such as ASTM C1115 for dense elastomeric silicone rubber used in building construction and ASTM F2038 for silicone elastomers, gels, and foams used in medical applications.
