Shuman Plastics Inc. of Depew, N.Y., is expanding its product line with a new flame-retardant polycarbonate/ABS alloy it introduced at NPE 2003 in Chicago, and will be doubling its capacity with a 50,000-pound blender in September.
Vice President Kenneth Shuman noted the alloy is limited to basic colors like black and gray.
The alloy combines flame-retardant properties, high impact strength, easy processing and good chemical resistance, and is self-extinguishing, the firm said.
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. Recommended processing conditions are 460Ã¸-530Ã¸ F.
The firm will be adding a third blender to its 20,000- and 42,000-pound blenders. Shuman Plastics employs 36 at its 137,000-square-foot facility.
