MoldX® A400For SMC, BMC, Hand Lay-Up, Epoxy and Polyurethane ApplicationsMoldX A400 is Huber’s highest performing optimized ATH grade. It is engineered to impart outstanding fire retardance and smoke suppression in fiberglass reinforced SMC without halogen additives. Formulations have better mechanical properties because less MoldX A400 is needed to pass the same flame retardant certifications that would be required of competitive ATH grades.

MoldX® A110For SMC, BMC, Hand Lay-Up and Polyurethane ApplicationsMoldX A110 is an optimized ATH fire retardant capable of very high loading levels, from 250 phr to greater than 350 phr. It is the choice for halogen-free product formulations requiring significant smoke suppression. The low-viscosity performance means MoldX A110 can be processed on SMC machines and BMC mixers at loading levels not thought possible. The outstanding flow characteristics of A110 make it especially well-suited for molding large or intricate parts.

MoldX® P18 ATHMeans Lower Pull Force

MoldX® S45For SMC, BMC, Hand Lay-Up and Polyurethane ApplicationsMoldX S45 optimized ATH is a non-halogen fire retardant product designed for fiberglass reinforced polyester applications such as SMC, BMC and laminating. MoldX S45 is engineered to allow higher loadings (180 to 230 phr) versus competitive ATH products and offers excellent processing.

MoldX® P18For Pultrusion, Resin Infusion Molding, Cured-In-Place-Pipe (CIPP), Vacuum Bag Molding and Filament Winding Applications MoldX P18 has an optimized particle size distribution with a D100 (top size) of approximately 18 microns giving excellent processing performance at fiberglass contents from 50% to 65% by weight. The lack of coarse particles allows for the fine particles to flow readily throughout the fiberglass in the composite. As a result, the pultruder can obtain a very low pull force and outstanding settling resistance with increased line speeds when compared to other ATH products. Readily achievable loading levels give fire retardant performance that permit the elimination of more expensive fire retardant additives.

MoldX® P12For Pultrusion, Resin Infusion Molding, Vacuum Bag Molding and Filament Winding Applications MoldX P12 is an optimized ATH product designed to be used in the most demanding fire retardant pultrusion applications (for example, when high ATH loadings and fiberglass content of 65% or more is required). When the fiberglass content is greater than 65%, MoldX P12 is recommended. MoldX P12 has a finer top size than MoldX P18, so MoldX P12-based formulations allow for faster line speeds and lower pull force at the highest fiberglass contents.

The graphs above show how increased ATH loadings result in a decreased heat release rate and decreased smoke generation. Huber’s MoldX® optimized ATH products allow for higher loadings at the process viscosity required by the formulator’s process. This attribute makes the MoldX grades very effective for imparting increased flame retardancy and smoke suppression to resin systems.
