Technology news

ExxonMobil Chemical Company has introduced Vistalon™ EPM* rubber 722 which can cost effectively improve processability and cable flexibility in medium and low-voltage wire and cable applications. In comparison with conventional EPDM, the metallocene-based product can provide processing improvements while exhibiting similar performance. Compared with cross-linked polyethylene (PE), it offers improved performance and excellent flexibility at low temperatures. And, it has improved electrical properties compared with metallocene EPDMs. “We have developed Vistalon EPM 722 for customers looking for improved productivity during cable manufacture and increased flexibility and durability in final cable construction,” said Ulf Nilsson, global EPDM product manager.

The new product is supplied in pellet form, making it clean and easy to use.

New system gives PCC control

Process Control Corporation, a supplier of auxiliary equipment for the plastics processing industry, has expanded its product line to include the Gravimetric Inventory Management System. With an increased number of processors searching for a method to weigh and store either re-pelletised material or delivered raw pellet materials, PCC recognised the need for an inventory management system. The system will accurately weigh re-pelletised materials prior to being re-processed or stored as inventory. The system can also be used to verify delivered resins before entering them into inventory. The system can be configured to operate in a continuous mode for loading silos or other surge bins for storage or as a batching system for loading Gaylord boxes for storage. The system can provide totals for a given production shift, a complete production run or an overall running total of material. It runs automatically with little or no operator intervention logging shift weight totals. Pellet material is conveyed either from a pelletiser, storage or delivery unit into a surge hopper via a pressure or vacuum system. The surge hopper has a high level view window for quick visual inspection of the material level within the bin, as well

as a clean-out door and a high-level proximity sensor. The high level proxi- mity sensor is provided to shut down the conveying system and prevent the system from over-filling. The material is then discharged from the surge hopper

through a slide-gate into a weighed hopper. Finally, the material is discharged through a second metering gate into either a Gaylord box or is conveyed to either a storage silo or storage bin via a vacuum or pressure system. The entire system is controlled with an easy-to-use touch-screen interface. The inventory data can be printed or transferred to an existing supervisory type inventory control system.

This annealer model, with an AC 22 kW motor, has a wire diameter range from 1.0-3.5mm. The rating is 3,000 Amp and the annealing voltage is approximately 45V. The annealing transformer and control system are built in two separate cabinets. A steam generator with sufficient capacity is included.
