Guill Tool introduces a co-extrusion crosshead designed for irrigation tubing

Guill Tool introduces Series 824, a co-extrusion crosshead designed for irrigation tubing with an emitter tool.   Manufactured from stainless steel, this new crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds.  Dual feed ports provide concentric compound flow, while the splits flow from one extruder to feed the inside and outside layers via a manifold assembly.   Series 824 is adaptable to all popular extruders on the market currently

EMI silicone now part of U.S. Department of Defense qualified products list

Specialty Silicone Products (SSP) announced that SSP-2569-65, an EMI silicone filled with silver-copper particles, is now part of the Qualified Product List (QPL) for MIL-DTL-83528, Type A. In a July 22 letter, the Defense Logistics Agency (DLA) informed SSP that SSP-2569-65, a 65 durometer conductive elastomer for shielding and sealing, passed qualification testing and has been added to QPL MIL-DTL-83528 for specific drawings and material types.

Thermoplastic polymer has API 610 recognition

CDI Energy Products announced that its latest material to achieve API 610 recognition outperformed service life expectations under extremely corrosive sulfuric acid conditions. API 610 is the standard for centrifugal pumps for the petroleum, petrochemical and natural gas industries. CDI’s proprietary thermoplastic polymer composite, Dures 200, was the foundation for critical components developed for an API 610 vertical single casing diffuser pump (VS1) for a high production sulfuric acid plant. CDI’s material scientists and engineers collaborated with the pump OEM to custom design suction bell eye case rings, bowl eye case rings and bowl bushings which could sustain differential pressures of over 200 psi, coupled with an extreme temperature profile of -20°F to 105°F (-28.8°C to 40.55°C).

Testing & Instruments

   

Endurica tames road loads with new software release

Endurica LLC announces a new feature in its Endurica CL fatigue solver: automatic block cycle generation. The feature enables users to extract a simplified durability testing schedule (known as a block cycle test) from multi-channel road loads recorded at the testing track. The simplified testing schedule preserves the most essential features of the original road load history, while maintaining the original failure mode and discarding non-critical load history.  The capability enables rubber part suppliers to design fatigue tests that execute quickly and that develop realistic damage. It enables car makers to ensure durability under actual driving conditions.

Latex and Natural Rubber

  

Staying relevant in a changing industry

In previous Rubber World columns, I have discussed the reintroduction of the manufacture of latex gloves back into the U.S. after a 25 year absence. During those years, in Southeast Asia, there have been significant, evolutionary improvements to the equipment, processing, formulations, and the latex itself. The challenge we face is to develop a competitive, sustainable manufacturing capability in the U.S., utilizing some of the personnel who were involved in glove manufacturing years ago, and merging their experience with new ways of thinking and problem solving.
