11 Molding Conditions for Kuramiron TM The typical molding conditions for Kuramiron TM are shown below. However these conditions are the reference data. The actual molding conditions depend on the machinetype, the product shape and so on. Therefore please adjust molding conditions properly.. 1 Extrusion conditions for #00, #2000, #000 and #9000 Series Hardness (Shore A) C1 Temperature Condition ( ) C2 C Adapter Die 0A A A A Injection conditions for #00, #2000, #000 and #9000 Series Hardness (Shore A) C1 Temperature Condition ( ) C2 C Nozzle 0A A A A Extrusion conditions for #000 and #A Series Hardness (Shore A) C1 Temperature Condition ( ) C2 C Adapter Die 0A A A A A

Molding of Kuramiron TM At standard temperature conditions, the heat stability is good. Leaving at high temperatures for long periods of time, the possibility of pyrolysis exists.. Drying of Kuramiron TM Thermoplastic polyurethane elastomer is moisture sensitive. Kuramiron TM is packed in moistureproof bags. However, it is recommended that the pellets be dried or hours at 0 prior to use. A dehumidifying hopper dryer or circulation air oven may be used for drying.. Recycling Kuramiron TM is a thermoplastic resin and as such, is recyclable and reuseable. Although it depends on the applications, generally the recycled material is blended with virgin resin for reuse. It is always important to confirm the properties of the recycled material before use..
