CAMX 2022 exhibit preview: Cimbar Performance Minerals
Cimbar’s halogen-free ATH solution for thermoset applications reduces resin costs in formulation, provides better wetout and faster line speeds and improves mold flow.
With increasing regulatory requirements, there is a growing need for specialty alumina trihydrate (ATH) products — a halogen free, flame retardant and smoke suppressant — that provide low-viscosity behavior at higher loadings. Cimbar Performance Minerals (Chatsworth, Ga., U.S.) introduces the Optiload “optimum loading” ATH series, which includes specially designed products suitable for a variety of demanding thermoset
composite applications.
In addition to meeting higher levels of flame retardant and low-smoke performance, Optiload’s advantages eliminate halogenated flame retardants; meet or exceed ASTM E84 Class A, UL 94 VO and 5VA; save on resin formulation costs; provide improved wetout and faster line speed; and improve mold flow.
The OptiLoad ATH lineup includes:
- OptiLoad LV-21: Suitable for pultrusion, RTM, vacuum bag molding applications, this solutions offers low smoke (exceeds E84 – Class A), has excellent wetout in resin and low settling.
- OptiLoad LV-45: Can be applied to SMC, BMC, hand layup, spray layup and urethane applications, with a a high loading/smoother surface, is low smoke (exceed E84 – Class A) and reportedly saves on resin costs.
- OptiLoad LV-110: Offered for SMC and BMC applications. It is low smoke (exceed E84 – Class A), offers high loading up to 400 phr, UL 723/ASTM E84 0-50 Smoke and maintains good mold flow.
- OptiLoad LV-410 XP: Suitable for pultrusion, RTM, vacuum infusion and resin pre-blends, this solution is said to have good flow in 60+% fiberglass systems, optimized resin stability, is low smoke (exceed E84 – Class A) and offers faster line speeds.
Cimbar offers a variety of particle sizes and surface treatments to improve mechanical properties and lower overall viscosity. Industrial applications include thermoset plastics (SMC, BMC, pultrusion), elastomers, latex backers, coatings and sealants. Cimbar’s product portfolio also includes barium sulfate
and talc used in a wide range of markets, including CASE, pharmaceuticals, engineered polymers, friction materials and drilling fluids.
The company Cimbar is headquartered in Chatsworth, Ga., U.S. and operates 16 production sites in the U.S., Mexico, China and Pakistan.
