Product Data SheetTrigonox 501-CS301,2,4,5,7,8-Hexoxonane, 3,6,9-trimethyl-3,6,9-tris(Et and Pr) derivs, 30%solution in odorless mineral spiritsTrigonox® 501-CS30 is an initiator for the production of controlled rheology polypropylene (CR-PP) and high-temperature polymerization of ethylene.CAS number1613243-54-1EINECS/ELINCS No.810-295-5TSCA statuslisted on inventorySpecificationsAppearance Clear liquid at 25°CColor40 Pt-Co max.Total active oxygen 5.17-5.48 %CharacteristicsDensity, 20°C0.86 g/cm³ApplicationsTrigonox® 501-CS30 is an efficient peroxide formulation for the production of controlled rheology polypropylene (CR-PP) in an extrusion process. Trigonox® 501-CS30 allows polypropylene producers great flexibility in controlling a polymer’s Melt Flow Index (MFI). Small changes in either peroxide concentration or process temperature can produce significantly different MFI’s. An important advantage of Trigonox® 501-CS30 is that the final CR-PP contains a low content of volatiles originating from peroxide decomposition products. Trigonox® 501-CS30 forms no acetone and no tert-butanol.Half-life dataThe reactivity of an organic peroxide is usually given by its half-life (t1/2) at various temperatures. For Trigonox® 501-CS30 in chlorobenzene half-life at other temperatures can be calculated by using the equations and constants mentioned below:0.1 hr170°C (338°F)1 hr146°C (295°F)10 hr125°C (257°F)Formula 1kd = A·e-Ea/RTFormula 2t½ = (ln2)/kdEa150.60 kJ/moleA 1.09E+15 s-1R8.3142 J/mole·KT(273.15+°C) KThermal stabilityOrganic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT110°C (230°F)Method The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria - United Nations, NewYork and Geneva).StorageDue to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.Ts max.40°C (104°F)Ts min.-30°C (-22°F)Note When stored under these recommended storage conditions, Trigonox® 501-CS30 will remain within the Nouryon specifications for a period of at least 12months after delivery.Packaging and transportThe standard packaging is a 770 kg Polyethylene Intermediate Bulk Container (PE IBC). Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Nouryon representative. Trigonox® 501-CS30 is classified as Organic peroxide type F; liquid, Division 5.2; UN 3109 for land and sea transport and classified as Organic peroxide type C; liquid, Division 5.2; UN 3103 for air transport.Safety and handlingKeep away from open fire, sparks and other sources of heat or ignition. Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of Trigonox® 501-CS30.

Make your workshop child proof with padlocks, master switches or by removing starter keys.14. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” arecareless acts that can result in serious injury.15. Maintain a balanced stance at all times so that you do not fall into the arbor press. Do not overreachor use excessive force to perform any machine operation.16. Use recommended accessories; improper accessories may be hazardous.17. Make sure the work piece is securely attached or clamped to the table.18. Remove loose items and unnecessary work pieces from the area before starting the machine.19. Do not overload the arbor press by using extension (cheater) bars.20. Use steel collars to support parts when pressing on bearings to prevent damage to the bearings. Familiarize yourself with the following safety notices used in this manual:This means that if precautions are not heeded, it may result in minor injury and/or possible machine damage.This means that if precautions are not heeded, it may result in serious injury or possibly even death.IntroductionThe arbor press is designed for riveting, swaging, bending, punching, and flattening. The arbor press can be used to press on or remove close-fitting bearings and bushings. It is suited for the production environment as well as machine shops, automobile repair shops, and home workshops.The anvil has four slots that are available for a variety of pressing operations.SpecificationsStock# ............................... 333605............... 333610............... 333620............... 333630 (333650)Model# ...............................

Failure to comply may cause serious injury!Arbor Press FeaturesThe arbor press (see Exploded view on page 8) consists of a cast iron base, an anvil, a pressing handle with lock knob, and a rack-type ram.The removable anvil has four cutouts that can be used for pressing off or pressing on bearings or bushings of various sizes.Set-up and OperationNote: The item numbers provided in the procedures that follow correspond with the item numbers in the exploded view in the Replacement Parts section, see page 8.Do not use the arbor press without first securing the arbor press to the workbench and anchoring the workbench to the floor.Mount the arbor press to the workbench or stand and secure with bolts using the holes in the base (1). Also, secure the workbench or stand to the floor..Changing Ram PositionThe ram has a flat surface on one end and a hole on the other end. The hole is used to accept the punch inserts. Change-out the ram as follows:A. Remove the handle by loosening the knob(17). Then remove one cap (5) from thehandle assembly. Remove handle (6) from the pinion (16).B. Remove the pinion retainer (14) by backingoff the Set Screw (13). Now slide the pinion retainer (14) off of the pinion (16).C. Pull up on the ram (4) enough to provideslack to remove the pinion (16) from the arbor press.D. Pull the ram (4) out the top of the arborpress body. Turn the ram (4) end-for-end.Hint: if ram does not freely come out of arbor press body loosening the two hex nuts (11) on side of arbor press body and the two hex nuts (11) on the front plate (12).E. Repeat steps A – D in reverse.MaintenanceA. Periodically lubricate the arbor press with alight machine oil.B. Wipe off or vacuum the accumulated debrisand dust after using the arbor press.C. Periodically check the ram for side-to-side andfront-to-back play. If the play is excessive, loosen the hex nuts (11) and adjust (tighten) the screws (10 on side, 9 in front) just enough to eliminate the excess play. Tighten them equally to assure even contact with the ram(4).D. Once the play is eliminated, hold the screw(10 or 9) in position and tighten the hex nut(11). Check to make sure the amount of playis acceptable.Parts ListsModel AP0-M – 1/2-ton Arbor PressIndex Part No. Description Qty1 .......... A P0-01 ............. B ase .. (1)2 ..........
