AMI Schedules PVC Formulation 2011 Conference

Applied Market Information (AMI) has announced that its PVC Formulation 2011 conference will take place at the Maritim Hotel in Dusseldorf, Germany, on 15-17 February 2011. AMI consultant Jon Nash will start proceedings with a review of the market recovery for the PVC sector. PVC compounder Ineos Compounds has studied the future alternatives after the move away from dibutyl tin stabilisers. The removal of heavy metal stabilisers is still a key driver of research.

Catena Additives has looked at the selection of impact modifiers alongside the shift from tin to calcium/zinc stabilisers, while Chemson Polymer Additive has examined the phase behaviour of the metallic stearate stabilisers. The trends are similar worldwide, with companies such as Kalpataru Organics developing heavy metal-free stabilisers in India. Minerals feature extensively in PVC; Kisuma Chemicals is examining the effects of hydrotalcite on heat stabilisation in Ca/Zn formulations.

Kuraray has found that polyvinyl alcohol can act as a co-stabiliser. PVC is widely used in construction, including cable. Burgess Pigment has looked at low-voltage insulation formulation using calcined kaolin clay. At the same time, Lanxess Deutschland has tested flame retardants such as phosphate esters for flexible vinyls. In terms of waxes, Clariant Produkte (Deutschland) has reviewed the use of different types, including metallocene PE. Processing technology is said to be essential for good production.

Coperion supplies equipment ranging from raw materials to the pellet stage, while K-Tron develops conveying solutions. The search for alternatives to phthalate plasticisers continues with a trend towards environmentally friendly chemicals. Danisco has developed bio-based plasticisers while Eastman Company has looked at non-phthalate plasticiser formulations for speciality plastisols. Lanxess Deutschland is testing triacetin as a component of P-PVC recipes. Adkeniz Kimya has looked at the sustainability issues of zinc stabiliser compounds in PVC.

BASF has developed 'hot' PVC, which has a higher softening point. Tony Gaukroger of Colour Masterbatch has patents in colouring uPVC with concentrates. PVC Formulation 2011 is intended to provide excellent international networking opportunities for the PVC industry, from end users to compounders and their suppliers. Research will be presented on the latest trends and technical issues affecting business development.

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.
