Eco-friendly green flame retardant felt – halogen-free, B1/A2 rated, UL94 V-0. Ideal for building insulation, automotive, appliances & industrial fire barriers. Recyclable & low smoke. Custom thickness from 3-25mm.

Product Name: Green Flame-Retardant Felt

Brief Introduction
Our green flame-retardant felt is manufactured using eco-friendly flame-retardant fibers (natural wool, recycled cotton, or pre-oxidized fibers) through a needle-punch process. It is halogen-free, contains no chemical binders, and features low smoke, non-toxic, and odorless combustion. It offers excellent flame retardancy, thermal insulation, sound absorption, and heat preservation. Compliant with green building material and environmental certification standards, it is widely used in building insulation, appliance thermal barriers, automotive interiors, and industrial filtration.
