EPU 41

overview highly elastic, tear resistant, and energy returning epu 41 is a production scale elastomeric material that is especially well suited for lattices where high resiliency is needed epu 41 has higher resilience (energy return) and better retention of elastomeric properties at temperatures > 10°c it is comparable to commercial tpus with a shore a hardness of 70 epu 41 example resource links about the material material overview and uses cases technical data sheet mechanical properties and data safety data sheet login required protocol sheet this downloadable pdf provides important usage information, including instructions about hardware storage resin dispensing & printing washing curing example protocol sheet print it out and bring it into the lab english https //archbee doc uploads s3 amazonaws com/uxbzokjjtgpphjapq8fvm l1aj2uiplsylc x 94szg 20250521 220114 pdf german/deutsch https //archbee doc uploads s3 amazonaws com/dptyqcthpbvzhe3zung4v hw5joejfrjrf3lsavfyjf 20241123 005836 pdf spanish/español https //archbee doc uploads s3 amazonaws com/dptyqcthpbvzhe3zung4v 7m1c12wn0h3kgmgqnwrmg 20241123 005849 pdf crystallization part a crystals epu 41 part a resin may crystallize at lower temperatures during shipping, resin containers may have been kept at low temperatures, so all part a containers should be incubated upon receipt follow the incubation method appropriate for the container size without the incubation step, epu 41 will be too viscous for mixing oven incubation method for containers that fit inside a standard thermal curing oven 5 l and 20 l bottles incubate part a component place one or more containers directly into oven or incubator space containers apart, in upright orientation set the time and temperature for 24 hrs (or up to 7 days) at 40°c (104°f) run oven or incubator to melt crystals carefully remove bottles from oven store cartridges at recommended temperature to prevent recrystallization the same oven used for thermal curing can be used to incubate cartridges instead of an oven, you can utilize a dedicated incubator for this purpose reference accessories & supplies docid 95twe3ttl 5ihi6dnl4xi thermal blanket incubation method for 180 l drum and 1000 l tote size containers reference this downloadable pdf for full instructions using a 1000 l tote container 180 l drum containers follow a similar method, swapping in drum accessories where appropriate https //archbee doc uploads s3 amazonaws com/dptyqcthpbvzhe3zung4v pvgjx qzyebf69lpaoqy8 20241123 005920 pdf notes allow for 48 hours incubation time additional drum or tote accessories are needed to facilitate incubation ensure that your facility is equipped to handle large industrial containers thermal blankets can be purchased for drum and tote size containers reference accessories & supplies docid 95twe3ttl 5ihi6dnl4xi part b crystals epu 41 part b can form salt crystals when left open in contact with air, or when liquid material is left around the mouth of the container avoid formation of salt crystals on rim of part b container with simple lab practices wipe mouth of container to clean off any resin prior to closing cap keep container closed when not in use part b loaded in an mmd counts as a closed container salt crystals on rim of part b container mmd dispensing epu 41 epu 41 is only available in bulk packaging for use with a meter, mix, dispense (mmd) system or other bulk mixing docid\ maobjiqt6krrinh11 e8d strategy set up for par3cm mmd follow par3cm instructions for filling 5 l and 20 l containers refer to meter mix par 3cm docid\ ro9omdzmwxqpwohukmhy2 page 180 l and 1000 l containers contact meter mix (par3cm manufacturer) for special considerations when working with industrial size containers follow protocol information for ratio, pressure, mixing tip, burn off heat settings part a 25°c part b no heat par3cm mmd
