Negative comments about our product the MTI hose, please delete that passage.
This is not helpfull. We often have problems with other companies writing things like that. He can write membrane products instead of MTI.
I like technical discussions with pro or contra.
Post: Wrapping Peel Ply Around Spiral Tubing For Infusion

Original Content:
If your resin is flowing in though the spiral wrap and you have only peel ply between the inlet spiral and your laminate then the resin flow will be 100% impeded from going anywhere fast other than through your spiral wrap.
The inlet piping or medium must have a decent contact and flow path to get into your laminate and any core or other flow mediums.
Some (including myself) will use peel ply only in contact with your outlet side vacuum channel/spiral tube/or other so that the resin front will near stop at your vacuum perimeter without filling your vacuum channel/piping/plumbing/spiral wrap.
It’s called a peel ply breaker, no need for wasting money on products like MTI hose.
Hanaldo is incorrect as the peel ply only will maintain a vacuum continuity, it’s no good for resin flow if your talking about having peel ply only on your inlet side.
