Fire Retardant Spray or Treatment for vinyl

[RDuplechin]

I have been looking at a fire retardant spray on aircraft spruce.  Inspecta-shield.  It appears to only work on absorbent items like fabrics, backings, carpet, etc.  I’m not certain of that however.  Does anyone know of a product that works on vinyl?

Thanks,

Rick

Our local 135 tour company uses a spray to meet Pt 23 burn every so often and they have vinyl in the cabin

I don’t see why you couldn’t spray it on test strips And have flame tests performed...

Will you be spraying both sides of the vinyl?

You should test a sample.  High quality vinyl will meet flammability standards.

My friend used the AS stuff and reported it works.   Forgot on what material.  Leather is really easy to pass the burn test.   I did 3 tests on 1 sample and it still passed.

Flame retardants for plastics are usually blended into the mix during production of the vinyl...

done at the same time as the color and the flexibilizer(?) is being added...

Since PVC can melt and flow and has the energy of gasoline when burned... spraying something on the outside of it, that is easily wiped off, may not be very helpful... over time.

Take a sample to the fireplace any size small strip can work pretty well... if it won’t stay lit... it probably has a flame retardant blended in it already...

When PVC burns it gives off HCl (hydrochloride acid) a very recognizable odor... and not very good for you Either...

PP thoughts only, not a mechanic...

Yes, plasticizers are added during compounding, along with color and fillers to improve strength.

Part 135 operators can use a spray on fire retardant to comply with Pt 23 burn requirements. I think it needs to be redone every 5 years.

Our airplanes actually don't need to go the full Pt 23 requirement as they are CAR-3 airplanes

There is a provision and procedure in Pt 43.13  that deals with this specifically. Our interior surface coverings only have to meet "some national standard".  That is acceptable to the FAA. As all upholstery materials sold in the USA need to meet a US standard. every manufacturer has a statement on their website as to what national standard their materials meet.
