                            聚醚型TPU

------------------------------------------------------------------------------

Description

DHK-E series TPU are polyether-based TPU for injection molding applications, supplied in form of transparent, translucent, colorless or slightly yellowish pellets with the characteristic of excellent hydrolytic stability, fungus resistance.It’s have excellent  ransparency,shore cycletime,esy to stickiness. It’s suitable to low temperature,flexibility and UV surroundings.

Applications:

Transparent profiles like toys,wires,or some higher requird on the color/shape

-----------------------------------------------------------------------------------------------------------

 

Working instructions:

According to our experience, the characteristics  of the extruder or injection molding machine that are suitable for processing DHK-E series are the

following:

●    L/D ratio between 18:1 and 22:1 for Injection molding

●    The screw must have 3 zones and a compression ratio between 2::1 and 3:1. Screws with a compression ratio greater than 4:1 should be avoided

●The screw should have a continuous regulation device and the working power higher than that for processing other plastics

 

For optimum results, previous drying of the product during 2-3 hours at 90~100℃ is advisable, in a hot air circulatory, vacuum or desiccant-air dryer. The suggested processing-temperature profiles are depicted in the table below.
