Specification-Grade Materials

Available in various commercial and specification grades (or spec-grades), rubber materials can widely vary in their properties and uses, from one grade to another. Aero Rubber manufactures extruded, molded, fabricated and sheet products from a wide range of rubber grades.

Commercial grade compounds are typically used for standard industrial applications, which only require basic tensile strength and elongation capabilities. Spec-grade rubber must meet more stringent standards for fluid resistance, tear resistance, ozone resistance, compression set, and operating temperature.

The more complex and demanding the project parameters, the more likely you will need specification-grade rubber components. Learn more about the different types and applications of spec-grade rubber, as well as how Aero Rubber can meet your needs.

Compound Standards

Aero Rubber’s products are manufactured from compounds formulated to meet these standards:

  • Proposition 65
  • REACH
  • RoHS

Spec-Grade Rubber Materials and Products

Spec-grade rubber is used when certain performance attributes are required. The following are some of the most specified grades for specialty applications.

ASTM evaluates and specifies the physical, chemical, and mechanical attributes of a variety of rubber and elastomer materials. The main codes that outline these standards are:

  • ASTM D1056
  • ASTM D6576

Rubber material used in military applications must have specific attributes that can withstand extreme conditions. Military specification rubber products, or Mil-Spec rubber, must meet the following standards:

  • MIL-R-900
  • MIL-G-1149
  • MIL-R-3065 SB
  • MIL-R-3065 SC
  • MIL-R-3065 RS
  • MIL-R-6855 Class 1
  • MIL-R-6855 Class 2
  • MIL-R-21252
  • MIL-R-83248C
  • MIL-R-83285

AMS regulates the quality of aerospace parts to ensure the safety of aircraft and fliers. The most important attributes are strength-to-weight ratio, toughness, stiffness, and durability. These standards are constantly reevaluated to keep up with the latest advances in process technologies and material science.

Aero Rubber manufactures custom rubber gaskets, sheets, and seals tested to meet these stringent industry standards.

  • Boeing BMS
  • Bombardier SMP

Federal Motor Vehicle Safety Standard No. 302 (FMVSS 302) assesses fabricated rubber products inside cars, trucks, and buses for burn-resistance capabilities. ASTM D2000, ASTM E662, and ASTM C542 further outline how much smoke generation and flame propagation is acceptable for rubber material in automotive applications.

SAE J200 Specifications

SAE International also dictates requirements for vulcanized rubber material — natural rubber, synthetic rubber, and/or reclaimed rubber—used for automotive purposes. Aero Rubber can develop products from high-quality rubber material to meet these specifications.

AASHTO and Cal-Trans Specifications

The American Association of State Highway and Transportation Officials (AASHTO) and Caltrans establish standards for highway and transportation infrastructure relying on rubber, such as elastomeric unreinforced and reinforced bearing pads. Aero Rubber offers natural rubber and unreinforced neoprene rubber bearing pads that meet these standards. 

Any rubber material used in food preparation needs to meet the following specifications:

  • ASTM D2000 / ASTM D1056 (Spec Grades)
  • FDA Title 21 CFR 177.2600
  • NSF 51, 61
  • 3-A Sanitary Standards
  • UL 94 HB, V1 and V0 Flammability Requirements

Medical-grade specifications, such as USP Class VI, require rubber materials to have excellent biocompatibility.

Rubber matting must meet certain physical, electric, and chemical standards. At Aero Rubber Company, we strive to stay up to date with these standards and cover all fields. The relevant codes include:

  • Rubber matting: ASTM D2000
  • Switchboard matting: MIL-DTL-15562
  • Molded slabs: AASHTO

Due to a variety of favorable properties, silicone material is essential in the transportation, electronics, cosmetics, food, and construction industries. The main specification for silicone products is A-A-59588, which supersedes ZZ-R-765.
