Ns-100 soft Grade foam
Silicone Foam
This medium-soft silicone foam is cast from liquid silicone and is designed to provide long term sealing, cushioning and vibration isolation performance. 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. It is a direct comparable to Rogers Bisco® HT 870 cellular material.
UL 94 V-0
- 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, and no dipping.
FDA REGULATION 21 cfr 177.2600
- This material is compliant with the requirements of FDA regulation 21 CFR 177.2600 that covers indirect food additives. Meaning it is generally recognized as a safe material and is intended for repeated use in contact with food.
