WEB EXCLUSIVE: Long known for flexible compounds, the Vinyl Div. of Teknor Apex Co., Pawtucket, R.I., now offers rigid standard and custom formulations for a broad range of uses, such as bottles, electrical conduit, home furnishings, irrigation connectors, retail displays, and medical devices. They are made in the U.S. at plants in Rhode Island, Tennessee, and California, drawing on technology transfer from Teknor’s Singapore facility, which has produced rigid compounds since 1969. More than 30 standard formulations are available. Two new examples are Apex RM 8002 and RM 8004 for injection molding small to medium-size parts such as valves, fittings, housings, couplings, and connectors for potable-water fixtures, water coolers, beverage dispensers, and irrigation systems. They are available in black, white, and colors for applications requiring NSF-61 certification. These grades boast better thermal stability than many other PVC compounds, permitting longer runs between mold cleanings, Teknor says.
