This is the most comprehensive evaluation of Layer-by-Layer (LbL) coatings intended to reduce the flammability of polymeric materials. Through a systematic variation of the coating recipe, an ideal combination of the coating attributes was identified that

The present work explores the extent to which the time-dependent mass loss rate of three common thermoplastics, PP, PA66, POM, and PET when exposed to pure radiant heat flux, can be predicted from first principles. The material properties which control the

Poly(lactic acid) was flame retarded using cellulose-based intumescing flame retardants. Cellulose was an excellent carbon source in combination with ammonium polyphosphate (APP), exhibiting good thermal stabilities and UL-94 ratings of V-0
Full-scale fire experiments were conducted at the National Institute of Standards and Technology (NIST) to investigate tire fire interactions with the passenger compartment of a motorcoach. A burner was designed to imitate the frictional heating of hub and

In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two methods
: An innovative twist to fabricating layer-by-layer coatings resulted in transparent, high-content clay coatings on porous polyurethane foam. The addition of an anionic poly(acrylic acid) (PAA) monolayer between anionic clay and cationic branched

Calculations have been performed for co-flow diffusion flames of propane and a propane-ethanol-water fuel mixture, prescribed for the Federal Aviation Administration (FAA) Aerosol Can Simulator, in the cup-burner configuration, with added CF3Br and C2HF5
Fire barrier fabrics are expected to play an increasingly important role in complying with existing and proposed soft furnishing flammability regulations. The number of commercial fire blocking technologies is large in order to accommodate the vast

Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion.1 Flexible polyurethane foams (PUF) are particularly prone to smoldering due to their high air permeability and low density. In this
