Self-extinguishing based on Sondor's internal test methods.
Non cross-linked expanded polyethylene foams do not weather well over extended periods of time if exposed to direct UV light. It is recommended that the product should be covered or painted with a suitable PVA paint if exposed to direct UV light.
Alternatively, change to Sondor SPX material for superior performance in extended UV and weathering applications. No need for painting or covering the product as this is a cross-linked expanded PE foam (Not supplied with the quick zip lock closing system).
