Victrex ST Polymer For Demanding Environments

Victrex has introduced the Victrex ST polymer product range, designed to perform in applications requiring a combination of high temperature, mechanical performance and dimensional stability. Victrex ST forms part of the Victrex Peek product family and has been launched with two grades: Victrex ST STG45 polymer (an unfilled grade) and Victrex ST ST45GL30 (a glass-filled grade).

The company said the polymer was developed to meet customers' needs for a high-performance material with improved mechanical performance at higher temperatures, while maintaining the properties of purity, electrical and chemical resistance, dimensional stability and low permeability and moistures. It added that Victrex STG45 has improved mechanical performance, especially in the temperature range from 150C (302F) to 200C (392F).

Victrex ST45GL30 features a heat distortion temperature of 380C (716F), opening up new application opportunities for customers who work at temperatures in excess of 300C (572F). Victrex said this combination of benefits provides customers another choice when placing applications in demanding temperature environments such as those found in the oil and gas, electronics or automotive industry.

Equipment or parts made with Victrex ST polymer have the potential to perform better, last longer and help customers realise long-term cost savings. Victrex ST polymer is a metal replacement option for many types of applications, such as gears, seals, rings, valve plates, wire coating, disk-drive carriers, connectors and test sockets.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
