J.M. Huber expands in calcium carbonate
ATLANTA — J.M. Huber Corp.'s Engineered Minerals Division plans to become a major supplier of wet-ground calcium carbonate for film and polyolefin compounding.
The company is investing $8 million in a carbonate plant in Fairmount, Ga., where it currently wet-grinds alumina trihydrate. J.M. Huber is headquartered in Atlanta.
Robert Baker, J.M. Huber polyolefins market manager, said the facility initially will produce carbonate particles in sizes of about 1 micron, but eventually will make particles that are even smaller.
J.M. Huber will offer product samples in September and begin offering commercial quantities in December.
Baker said J.M. Huber has been making small quantities of wet-ground carbonate at its Quincy, Ill., carbonate mine.
The Quincy operation is a major producer of dry-ground carbonate used in plastics and other applications. Baker said J.M. Huber wants to expand in the higher-value markets for fine carbonate.
J.M. Huber's new plant will have annual capacity of about 150 million pounds. The company will source raw material from its Marble Hill, Ga., underground mine.
AlphaGary develops easy-processing TPEs
LEOMINSTER, MASS.—AlphaGary Corp. debuted in North America a line of styrenic block copolymers it said are easy to process.
Evoprene thermoplastic elastomers have been used in Europe for window profiles, automotive, toys and other applications. The Leominster firm touts them as a cost-effective alternative to rubber.
Evoprene Super G, a grade suited to high-temperature, high-performance uses, has hardness of 30-80 on the Shore A durometer. AlphaGary said it has low compression set and less tendency to neck when stretched over rigid parts.
Washington Penn has wood-filled material
WASHINGTON, PA. — Washington Penn Plastic Co. Inc. added wood-filled plastics to its line of filled compounds.
Wood-filled plastics are lighter than mineral-filled materials but they offer similar performance, the Washington-based company claimed. Washington Penn Plastic said it will target molding and extrusion applications in automotive, construction and other markets.
North Wood Plastics Inc. of Sheboygan, Wis., will produce the highly loaded wood compounds for Washington Penn using a patent-pending process.

PC compounds boast more fire retardance
NEW YORK — Ashley Polymers Inc. has developed three polycarbonate compounds that it says have better flame-retardant properties than the PC it introduced last year.
The Ashlene-brand materials have melt flows ranging from 6-20 grams per 10 minutes, according to the New York-based company. The compounds' flame-retardant ratings include Underwriters Laboratories Inc.'s 94-V0 at 0.058 inch.
