Moulding Materials

Nylon 66, having a higher heat resistance, is tougher, more rigid and has low creep at high temperatures.<br><br> Available in Flame Retardant and Non Flame Retardant. Thermoplastic Polymers 3 PBTP and PETP These materials are increasingly selected for applications where high stiffness, low moisture absorption, dimensional and thermal stability characteristics are required. DuPont RYNITE PET polyester resins have the additional advantage of UL1446 system approvals allowing high temperature classifications to be met.<br><br> Polyphenylene Sulfide 3 PPS PPS has a high resistance to deformation, benefiting from extreme stiffness and is very stable at high temperature. Inherently non-flammable. Liquid Crystal Polymer 3 LCP LCP benefits from superior high temperature performance, dimensional stability whilst moulding extremely thin sections.<br><br> REINFORCED PROPERTYASTM TEST UNITS Nylon 66 F/R Nylon 66 Nylon 66 F/R Nylon 66 F/R Nylon 46PBTPETHTNPPSLCP Tensile Strength at BreakD638MPA8375186135100141152214155145 Elongation at break D638 - 60 3 3 2 7 2.4 2.3 2.4 0.05 2.2 Flexual StrengthD790MPA-125-205235217221-260174 Compressive Strength D695 MPA 34 - - - 170 - 172 - 179 89 Impact StrengthD256J/M5371171223118859669225 Flex Moduls D790 GPa 2.8 9.0 9.6 10 10 13 Underwriters lab ratingsUL94V-2VOHBVOVOVOVOHBVOVO Oxygen Index D2863 %O 2 31 32 - 32 37 35 33 - 46.5 39 Glow Wire TestVDE 0471 o C850960650850960750 Part 2-1/IEC(1.0)(1.0)(1.0)(1.0)(1.2)(1.0) 695-2-1 Dielectric 1 Khz D150 4.0 - - - 4.5 4.2 4.1 4.4 3.8 3.5 Constant 1 Mhz D150 3.9 - 4.5 - 4.5 4.2 4.1 4.0 3.8 5.5 1 Ghz D150 3.6 - 3.7 - 4.5 4.2 4.1 - 3.8 3.5 Comparative Tracking Index* D3638volts-575600+575250--600+200167 Arc Resistance D495 Seconds - - 135 - - - 117 34 - Volume resistivityD257Log (ohm- cm) 13141514101515151516 Thermal expansion D696 cmcm/ o C 7 6-7 2.3 2-3 5 2.5 2.5 - - 1.4 -50 o C - 200 o C X 10 -5 Heat deflection temperature D648 o C90135249250284208224260260295 Water Absorption 24 hours D570 - 1.2 1.15 0.7 0.75 0.9 0.05 0.05 0.4 - 0.002 Specific GravityD792KGM-31.141.171.381.381.681.721.671.471.671.47 * CTI may vary depending on colour and grade specified.

Not all of these materials are offered as standard on all products, details of standard materials for products are shown on the catalogue page. Should alternative materials to the standard mater ial be required (including materials not shown) a request to our sales department should be made prior to ordering, minimum order quantities, and machine setting up charges may apply.<br><br> GNN is Miles Platts material code for a 30% Glass Reinforced Nylon to a flammability rating of UL94HB 3 We currently use the ma terials as listed above, but we reserve the right to use an alternative material of the same or better characteristics should quality or commercial reasons arise. UNN is Miles Platts material code for an Unreinforced Nylon (used primarily for Insulation covers and potting boxes) to a flamm ability rating of UL94V2 3 We currently use the materials as listed above, but we reserve the right to use an alternative material of the same or better characteristics should quality or commercial reas ons arise.

Information on prices and availability should be discussed with our sales office.<br><br> * For specific material requirements use the Specific material code. Where a specific material grade is required for third part y accreditation, this must be agreed in advance with Miles Platts. Please ensure that the required material is clearly indicated on your order.<br><br> **Recommended maximum system temperature classification may have been obtained by means of testing through UL1446 or interpreta tion of IEC60085 / IEC 61587, please contact our technical office for further information. *** DuPont Zytel 70G30HSLhave now various Class F 155oC Systems available. Many systems have been recognised by UL1446.<br><br> Many materials have been incorporated into systems class ratings up to Class R 240 oC. Complete details of these systems and information of how to apply them are availalable from our Techincal sales department. The materials listed above are those which we currently use on a regular basis, a further wide range of materials can be used if required, please contact our Technical sales department for further details.<br><br> Responsibility For Selection The responsibility for the selection of appropriate materials and systems lies with the manufacturer of the electro-technical p roduct. Only experience or adequate acceptable tests provide basis for assigning rational temperature limits for the insulation. Service experience is an important basis for the selection.<br><br> Author J.Weston Last update 07/10/03 Most products are available direct from stock with same day despatch - please contact sales for details Final Pages APPROVED 5/10/04 9:06 AM Page 149
