Toray Plastics Introduces Lumirror PA30

Toray Plastics (America), Inc. created a new, versatile, tack-sealable, polyester (PET) Lumirror PA30, a symmetrical transparent film technology that is modified on both sides for improved printing and laminating adhesion. Therefore, either side of the revolutionary new film offers two different performance capabilities.

In addition, Lumirror PA30 can also be used to tack seal to itself, or can be used to lap seal the inside surface of a lamination to the outside surface. In the latter, a lamination made with a heat-sealable polyester film, such as Toray’s Lumirror PA25, is on the inside sealing surface, and Lumirror PA30 is on the outside. Permanent laminations and strong seals help deliver a better food product and ensure brand integrity.

“Converters and leading consumer product goods companies seek state-of-the-art packaging materials that drive business and creativity,” says Steve Sargeant, Ph.D., director, new business development, Toray Plastics. “Versatile, value-added two-side-treated polyester Lumirror PA30 is a breakthrough, brand-building packaging development.”

Co-extruded polyester Lumirror PA30 also offers significant production benefits. Its physical properties allow it to be easily laminated, printed, or vacuum metalized. Polyester Lumirror PA30 handles well on high-speed equipment for improved processing and better production yield, and is easy to convert and print on. In addition, it offers excellent thermal stability and superior mechanical properties, including high strength, dimensional stability and optical clarity.

Flowserve Launches Single Mechanical Cartridge Seal

Flowserve Corp. a global provider of fluid motion and control products and services, has launched the Flowserve GCX single mechanical cartridge seal. The GCX is specifically designed for ANSI and DIN pump services, where the pumps and seals are required to operate in multiple chemical environments without chemical compatibility change-outs. The Flowserve GCX seal is ideally suited for intermediate and batch chemical processes in short-run chemical plants and in multiple campaign specialty chemical and pharmaceutical plants using solvents and steam for decontamination.

Built with durable metal to withstand corrosion and harsh chemical conditions, the GCX features an alloy C-276 bellows, 316 stainless steel components, and flexible graphite foil secondary seals. Elastomer components used in competing seals are not suited for variable, harsh chemical conditions and are susceptible to corrosion and degradation, especially in multiple chemical applications. The metallurgical components in the GCX also enables it to operate in a wider temperature.

Batch processing and intermediate chemical pumps often handle multiple pH level products as the processing moves from start to completion. Since secondary are not possible during processing, a seal that can withstand these differing conditions is the ideal.

“The GCX is the perfect solution for pumps in aggressive and multiple exposure chemical applications,” says Mark Fallek, vice president, marketing, Flowserve Flow Solutions. “Chemical streams often have unknown compatibility. These streams can include different chemical and batch processes, as well as proprietary chemical mixtures. Seals using a predominance of elastomer components are inadequate for this type of service.”

The GCX alloy C-276 drive mechanism and minor parts are isolated from the process fluid to minimize chemical stress. An inboard shaft O-ring resists particulate build-up underneath the seal sleeve, facilitating easy removal of the seal. It also has a standard throttle bushing with vent and drain ports to allow the use of nitrogen or steam quench to mitigate coking.

Designed as an OEM or aftermarket seal, the compact design of the GCX fits most stuffing boxes in non-Group 1 ANSI or DIN size pumps. Its cartridge design enables easy installation and removal for service, and is compatible with enlarged and standard bore seal chambers. Field-tested in a variety of chemical processes, the GCX offers excellent runtime and a high mean time between repair (MTBR).
