Certified Fire Testing results for rotational molded HDPE
Certified Fire Testing results for rotational molded HDPE
(OP)
Hello, I am new to this forum. Hoping I can get some guidance. We are in need of qualifying HDPE as a part of building material for manufactured housing program for HUD and HCD. The following test results are required by the 3rd party agency qualifying the material. Agency will qualify the results from certified lab to bypass the necessary testing. Below is a list of required testing the third party agency is looking for. Could anyone help to identify any existing lab results of below required test? Thank you in advance for any information.
HDPE for rotational molding being considered:
A. Polyaxis RLLP 621 is a flame retardant high density polyethylene
B. RF-2000 by Spectra colors or equivalent.
C. Marlex HMN®TR-945 / HMN TR-945GHIGH DENSITY POLYETHYLENE
List of required testing:
1. Building elements, components and assemblies of floors, roofs and walls need to be tested per ASTM E119 or UL 263 (2016 CBC 703.2).
2. To classify a material as non-combustible; it shall be tested in accordance with ASTM E136 (2016 CBC 703.5.1).
3. Roof assemblies will be tested in accordance with ASTM E108 or UL 790 (2016 CBC 1505.1)
4. Exterior walls will be tested in accordance with NFPA 268 (2016 CBC 2603.5.7)
5. Flame Spread and Smoke Developed Index
6. Where HDPE is used as interior finish, it shall be tested in accordance with NFPA 286 (2016 CBC 803.9).

You answer may be in the SFPE Handbook of Fire Protection Engineering, which has an extensive chapter on polymeric materials. Another source is the Ignition Handbook.
To your question about an acceptable polymer that is a candidate for rotomolding, sorry but I can't help you with that as only deal with plastics from the end use and fire protection perspectives - I have no experience with it's fabrication and which polymers work for a selected fabrication method.
