TPE Replaces Liquid Silicone In Electrical Insulators

Since the 1970s, insulators used in power distribution have evolved from porcelain to cast epoxy to liquid silicone rubber (LSR) and now to thermoplastic elastomer. In the last three years, GLP Hi-Tech Power Products Inc. in St-Jean-sur-Richelieu, Que., has been injection molding a new type of dead-end composite insulator with an overmolding of Dytron XL TPE from Applied Elastomer Systems, L.P. (AES), Akron, Ohio. GLP molds the insulators in lengths from 13.1 to 22.6 in. They weigh 1.7 to 2.3 lb.

Dytron XL is a non-halogenated, flame-retardant compound with a polypropylene matrix containing dynamically vulcanized rubber and alumina trihydrate. It was developed specifically for wire, cable, and other electrical applications. Until recently, it was available mainly in Europe. AES is now beginning to market it actively in North America, where it is finding new uses such as molded insulators for electric rail systems.

This TPE beat LSR in laboratory tests of dielectric strength, which registered 12.59 kV/mm for LSR and 21.96 kV/mm for Dytron XL. The TPE also passed the stringent FVO flammability test, as well as the 1994 and 1996 tracking-wheel tests, two severe measures of insulator performance in pollution and salt-spray conditions.

Decoma Licenses Foam-Core Composite Technology

Tier-one automotive supplier Decoma International of America Inc., Concord, Ont., has obtained an exclusive license for the automotive marketplace to use the Strata composite technology of Advance USA LLC, Old Lyme, Conn. Decoma is evaluating uses of the technology for making light-truck tonneau covers, modular closeouts for hybrid SUVs, and automotive roof systems. Strata involves thermoforming weatherable thermoplastic sheets, assembling the sheets in a press together with layers of reinforcing fibers, and then injecting urethane foam chemicals to form a stiff, lightweight core. Resulting parts can weigh up to 40% less than thermoset SMC.

New GE Center Speeds Color Development

GE Plastics, Pittsfield, Mass., has opened a new facility to help designers and OEM marketers quickly create custom colors and special effects for engineering thermoplastics. The new 4000-sq-ft Customer Innovation Center is located at GE Colorxpress Services in Selkirk, N.Y. It brings under one roof all of the resources needed to select and develop custom colors and produce color chips, pellet samples, and even prototype parts in a single day. The Center expands GE’s Colorxpress Services, which include Internet on-line color selection, custom color matching, Micro-Lot matching, and color management programs. For $2500, the Center can develop a custom match and deliver sample chips in 48 hr. The Center’s facilities and capabilities include four key areas:

  • Development consulting helps customers refine the looks and functional specifications of their products through discussions of part design, quality, color and effect development, and tooling.
  • A constantly growing library of more than 20,000 color chips can be viewed under various standard lighting conditions. (GE will also open two satellite chip stations in Detroit and San Francisco in the first quarter of 2001.)
  • Color blending and matching lab will formulate colors and initiate trial runs for customers. Within minutes, a batch of pellets can be ready for molding a set of sample chips on one of the Center’s injection machines.
  • If a customer supplies tooling, sample parts can be shot in the molding machine for evaluation of the new custom-designed color.
