Huntsman Provides Composite Parts for Concept EV

Huntsman has announced its technical involvement in a project that showcases the possibilities of building a concept electric car - the 'U-Box' - using environmentally sustainable components. The car will have its first showing in France at JEC Paris in March. The U-Box incorporates differentiated materials, including renewable flax and basalt fibres for reinforcing composite parts in combination with new toughened resins, as well as halogen-free, fire-resistant resin.

Flexible Organic Light Emitting Diodes (OLEDs) have also been integrated in the composite structure of the U-Box. In addition to this, Huntsman equipped the vehicle with composite wheels and provided composite bonders offering high strength, flexibility and temperature resistance. On its stand, Huntsman will also be showing Araldite MY 0816, a naphthalene diepoxy announced at JEC 2009, which will be complemented by additional new building blocks such as a fluorene diepoxy resin and a diaminodiphenyl sulfone based hardener.

The company is also adding to its range of Araldite benzoxazine thermoset resins with recently developed liquid, solvent-free products. Targeting aerospace interior applications, a new low-viscosity RTM/infusion system was developed with excellent FST (fire-resistant, low-smoke and toxicity) properties. For the production of wind blades and other large composite parts, Huntsman has developed two new resin systems. The first of these resins provides very low viscosity, while the second, Araldite LY 1568/Aradur 3489, offers low build up of exothermal temperature during curing.

For this market, Huntsman has also introduced a new tough and crack-resistant adhesive system, Araldite AW 4856/Hardener HW 4856. Huntsman will also be introducing new formulated systems for high-performance epoxy pre-preg and infusion systems for structural and tooling applications. Other products on show include Renpaste 4688, a seamless modelling paste for quick pre-preg tool build-up on high-output automated equipment.

The polyurethanes division of Huntsman will introduce Vitrox composite resin - a new resin range that can be used in fast cycle, resin transfer moulding (RTM) for high-volume, automotive and mass transportation parts production. Completing the line up at this year's JEC show is a complete range of adhesives based on epoxy, methacrylate and polyurethane, as well as MS polymer-based chemistries containing an EP-based paste adhesive for bonding structural aerospace composites.

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.
