New flame retardant made for thermosets
Huber Engineered Materials has developed an alumina trihydrate flame retardant especially for pultrusion and other thermoset processing.
MoldX A3 has a particle shape designed to reduce pulling forces and to provide higher loadings and faster line speeds in pultrusion, according to the Atlanta firm.
The Huber controlled-function technology gives MoldX A3 particles a special morphology for viscosity control and wet-out at high loadings.
In addition to pultrusion, the flame retardant is well-suited to resin transfer molding and sheet and bulk molding compounds, the company said.

HDPE coating resin offers improvements
Chevron Phillips Chemical Co. LP said it has improved its high-end extrusion coating resin HiD 94312 MarFlex.
The high density polyethylene has low coefficient of friction, high grease resistance and good stiffness and printability, according to the Woodlands, Texas, company.
The product has a melt index of 12 grams per 10 minutes.
CP Chem also claims the resin has excellent drawdown capability, and good bonding and thermal stability to provide reliable converting.
The MarFlex resin is well-suited for release liners, packaging greasy foods, multiwall bags and paperboard coating, the firm said.
The HDPE complements CP Chem's low density PE extrusion-coating resins.

Specialty PS targets applications for ABS
Nova Chemicals Corp. is offering a new specialty, tough polystyrene that it said is easier to process and more economical than ABS in the production of appliance components and housewares.
The FX550 material provides high impact resistance, high gloss and environmental stress-crack resistance, the company said.
The resin has a high melt flow, is easy to color and does not require drying, according to Nova officials.
Initial applications include refrigerator shelves and office supplies, but the Pittsburgh resin company foresees applications ranging from vacuum cleaner housings to packaging for cosmetics and point-of-purchase displays.
