Coarse Alumina Trihydrate (ATH) is the standard flame retardant for commercial and industrial carpet applications which require UL fire code approvals.

Because ATH is used at very high loading levels in carpet backing, any variability will have a negative impact on viscosity. Huber uses statistical quality control techniques to ensure consistent performance.
