Heritage Plastics Inc. hopes to grow its polyolefin compounds beyond the film market with new grades for blow molding, sheet extrusion and injection molding that were introduced at NPE 2003.
Picayune, Miss.-based Heritage earlier this year began producing three grades of high density polyethylene compounds for blow molding, two grades of HDPE compounds for extrusion and a single grade of polypropylene compounds for injection molding, President Scott Brann said by telephone.
All of the new materials are based on Heritage's Minapol-brand mineral additive technology.
``Minapol was developed for thin-film applications and we've maximized it in that area,'' Brann said. ``Now we've taken the technology beyond film.''
Heritage's blow molding HDPE compounds are being used in household industrial chemical bottles, Brann said. Uses for the firm's injection molding PP compounds include power tool cases.
Processors can use Minapol technology - which can achieve loadings of up to 80 percent using calcium carbonate, talc or other materials - to make thinner parts and reach raw material savings of 1-3 cents per pound, officials said.
The firm had done minimal work outside of film, but Brann said he expects nonfilm markets to account for half of heritage's total sales by the end of next year.
Heritage added a 50 million-pound-per-year extrusion line in Picayune late last year and may add another line later this year or in 2004, based on sales of the new products.
The firm currently has 300 million pounds of annual compounding capacity.
Heritage also has increased its sales force from two to five since late 2003 in anticipation of marketing the new materials, Brann said.
In addition to its 180,000 square-foot plant in Picayune, Heritage operates a sales office and research and development center in Atlanta. The privately held firm does not disclose sales figures.
