List some MFI improver (Melt Flow Index) for Polyolefinic polymers !?

Its better to get a design engineering guide from one of the plastic raw material suppliers as modifying the melt flow index would change many other properties also. A manufacturer rather than a distributor would probably provide you the information more readily.

The density of hdpe is 0.95-0.97 g/mL.  So do the math: mass (aka weight here) = Volume * Density.  I'm assuming you're capable of that or else you wouldn't be asking about hdpe.

If you mean polysesquisiloxane ( a cosmetic silicone ) try Dow Corning or Wacker for industrial quantities. If you are after small quantities, try \n\n www.soaperschoice.com

Not sure about using "welding rod", but I know you can spot weld and ultrasonically weld Polystyrene to Polystyrene quite well.  There is "General Purpose" and "Rubber Modified" Polystyrene.  The rubber modified is easier for spot welding, swaging and staking, so I'd assume is easier for other methods of welding.  If you use welding rod, it would need to be Polystyrene (You may get some bonding with Polycarbonate as well).  Haven't seen welding rod in either of these materials though....  maybe someone else has??

have you tried silicone rubber.  tensile is typically better than 1500 and 55 shore a is average.

You can find international suppliers at the reference.  It appears that many materials are used including plastic and aluminum.
