More Information
UL 94 V-0
- UL 94 V-0 is a safety and flammability standard by Underwriters Laboratories.
- This material is compliant with the UL 94 V-0 test standard for flammability.
- The vertical burn test measures the self-extinguishing time of a vertically oriented polymer specimen. The test evaluates both the burning and afterglow times and dripping of the burning test specimen.
- In order to be rated UL 94 V-0, the burning must stop within 10 seconds, no flame propagation or dripping.
21 CFR 177.2600
- 21 CFR 177.2600 is a specification from the U.S. Code of Federal Regulations (CFR) used by the Food and Drug Administration (FDA).
- This material is compliant with the requirements of 21 CFR 177.2600.
- The specification covers rubber articles intended for repeated use and may be safely used in producing, manufacturing, packing, processing, preparing, treating, packaging, transporting, or holding food, subject to the provisions of this section.
- Meaning this material is generally recognized as safe, and can be used in applications where repeated use in contact with food occurs.
ASTM D1056 2D2
- ASTM D1056 is a specification for flexible cellular materials (sponge or expanded rubber) from the American Society for Testing and Materials.
- This material fully passes the ASTM D1056 2D2 specification for flexible cellular materials.
- The specification covers flexible cellular rubber products known as sponge rubber and expanded rubber, but does not apply to latex foam rubber or ebonite cellular rubber.
- Type 2 – Closed-cell rubber.
- Class D – Cellular rubber made from synthetic rubber can meet extreme temperature resistance −103 to 347°F (−75 to 175°C).
- Grade 2 – For Types 1 and 2 cellular rubber, has a compression deflection range from 5 to 9 psi (34.5 to 62.1 kPa).
ASTM D412
- ASTM D412 is a standard test method for evaluating the tensile properties of rubber and elastomers.
- It measures key properties like tensile strength, elongation at break, and tensile modulus, assessing how materials perform under tension.
- The test uses two methods (A and B) to determine a material’s ability to stretch and resist breaking.
- ASTM D412 is critical in industries such as automotive and construction, ensuring rubber products meet performance standards for strength and flexibility.
