German NS-100 Soft Silicone Foam
Cellular Silicone Foam
This soft silicone foam is cast from liquid silicone and is designed to provide long term sealing, cushioning and vibration isolation performance. It is a direct comparable to Rogers Bisco® HT 870 cellular material.
Most importantly, it offers UL 94 V-0 flame resistance, FDA compliance for repeated use in contact with food and has excellent low stress relaxation properties which helps protect against compression set.

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.
FAR 25.853
- FAR 25.853 is a regulation part of the Federal Aviation Regulations (FARs), specifically addressing flammability requirements for materials used in the construction of commercial aircraft.
- The regulation mandates that materials used inside the aircraft cabin, such as seat cushions, wall panels, and flooring, must be flame-resistant and able to withstand specific fire tests.
- It includes specific criteria and test methods for assessing the flammability of these materials, ensuring that they do not easily ignite and, if they do, that they burn slowly and self-extinguish.
- Compliance with FAR 25.853 is critical for aircraft certification, focusing on enhancing passenger safety by minimizing the risks associated with in-flight fires.
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.
