I have been informed that the Eastman Copolyester material that I was hoping to use is not recomended for UV exposure. We are very concerned now as we were about to cut steel and comission an injection tool but have had to put the breaks on. The COPE ticked all our boxes for the floowing...

If injection moulded PUR is used in a hot water situation (80-90 degrees C) what life could we expect? Have I heard right that PUR is prone to hydrolytic instability?

Thanks.

I got a list now of the following: DSM Anitel Eastman Neostar Ticona Riteflex RTP 1500 Series Toyobo Pelprene The trouble now is finding any of these in my part of the world (NZ)... dont want to have to buy in a full pallet of it for our small requirement. we only need half a bag every 4...

Hi Everyone.... My Plastics molder says that Hytrel is the right elastomer to use for our application but because we only need a small quantity we might as well forget asking Dupont. What other alternatives are in the Co-Polyester family that might be more readily available and perhaps cheaper...

btrueblood, I also agree with you that the loads are far in excess and the method appears to be obscure relating to my original request. The only test equipment we possess is a torque wrench and a 20T press with pressure transducer so I was limited in what I could test for. My thought was to try...

Pud, I inherited this design from the previous engineer, but your comment is valid and has been discussed about possibly changing the fastener and modifying the tooling to suit.

Hi people, thought you might be interested to see some data from tests just done on actual moulded components. We placed our part in a 20T shop press with a 90degree cone shapped plunger attached. The cone pushed into the corresponding countersunk recess hole in the moulding. I aatched a Dial...

Ok Guys.. I think from a factor of safety point of view I might stay away from the Polyester, that sounds too dificult for our simple moulder to handle. We really dont want this product to relax over time. It need to screw tight and keep the tension over time on as best as possible. So I think...

Thanks guys, We had previous tested a Glass Bead PP on a related product recently and found that it did not have the stiffness or strength required. Fresh mouldings of GFPP were weaker than the aged lupox (PC/PBT) after the lupox had been soaked in concentrate iodine for 3 months. We like the...

Would appreciate your comments please on the difference between Nylon 12 and GFNylon 6.6 in particular to the properties of 1:Chemical resistance, 2:Impact resistance 3:Creep. I have an injection moulded component that is used in the dairy, it is fastened with two CSK 316SS screws into a...
