why are no canopies made from porcher pn10?

[lyosha 50]

Typically pn4 (standard zp) is used. But they also have pn10 (low bulk zp). I'm curious if any manufacturer has tried to make a canopy out of it, and if not what about the material makes it unworthy?

I would guess the differential strength and elongation between warp and fill and the weaker tear strength.

The breaking strength is still stronger than PN9 - low porosity used widely in low bulk parachutes.

Is it really only the fill elongation? Has any company actually tried to use the stuff?

The main reason is the cost. Porcher is a French company and the shipping and taxe and duties are an important variable in the cost of this product. Its the same for EEC manufacturer importing US fabrics.

Porcher PN4 (standard ZP) and PN9 (low bulk F-111) is commonly used by many companies both Europe and America to make canopies that are in the market

I know but if you compare cost the gap is important and they aren't so many in the US.

How much more expensive is PN10?

I mean, manufacturers often pass the additional costs through to consumers (i.e. ZPX Pilot costs more than standard ZP). There are plenty of people who pay the premium for a variety of reasons...
