CHICAGO (July 7, 2:50 p.m. EDT) — Shuman Plastics Inc. of Depew, N.Y., is expanding its product line with a new flame-retardant polycarbonate/ABS alloy it is introducing at NPE and will be doubling its overall capacity with a 50,000-pound blender in September.
The thermoplastics compounder and resin supplier is exhibiting at its 11th-consecutive NPE, according to President Charles Shuman, 73. The company is near Buffalo, N.Y.
The flame-retardant alloy was developed for a customer who needed a cost-effective way to mold cable top boxes, said Vice President Kenneth Shuman.
“It is really cost-competitive vs. prime materials,” said Kenneth Shuman, noting that the product is limited to basic colors like black and gray.
However, the strength of the alloy is that it combines flame-retardant properties, high impact strength, easy processing and good chemical resistance, and is self-extinguishing.
Among its particulars, the compound has an IZOD impact strength of 9 foot-pounds, tensile strength of 7,000 pounds per square inch and a flex modulus of 350,000 psi. It has a flame-class rating of V0 based on a notched, one-eighth-inch-thick specimen. It has a melt-flow rate of 7 grams per 10 minutes. Lastly, the recommended processing conditions are between 460º and 530º F.
Kenneth Shuman said the product may be used for such applications as consumer appliances, housewares, electronics and specialty spools and reels.
He said the company focuses on polycarbonate, ABS and PC/ABS alloys and will be adding its third blender. It already has 20,000- and 42,000-pound blenders. Shuman Plastics employs 36 at its 137,000-square-foot facility.
A third-generation company, Shuman Plastics was established in 1947 by Philip Shuman.
The company also buys and sells surplus, obsolete and scrap material and provides toll processing services. Shuman has a proprietary line of purging compounds for injection molding, extrusion, blow molding and compounding.
