Not to confuse or convolute things, this is a discussion from the below thread, as it kind of morphed in to discussing plasticizers used in PVC, from post #9 onwards.
So just to recap, I'm dealing with a sourcing company in Melbourne Australia. These folk travel to China and check out the manufacturers, quality controls to make sure what the client is wanting to purchase, they are actually going to get. I'm going down this root as Alibaba's scale of risk is way to high, should anything go wrong.
I submitted my project a month ago, the guy has been to china and has come back with a reply as of yesterday. I distinctly asked for DOP/DEHP based PVC with no ESBO, ELO, nor DINP. He noted that he'll ask the factory upon visiting china, and upon his return, this was part of his reply.
"In regard to the PVC it’s very difficult to be so specific with technical properties for a shipment of this size. It would likely need to be 50 to 100 times larger to be able to specify certain chemical properties and the material be made to order. At your quantity, the factory will purchase fit for purpose material within reasonable and safe requirements. Their official reply is as follows; “Sorry, we don't have the technical data sheet of the PVC. The quotation I gave you is environment-friendly material, which is fully in line with export standards.” "
So I surmising the manufacturer he is dealing with already has purchased the raw sheets of PVC, which will get cut and stitched to the clients order upon a request. So this would beg the question, if they are still factories that make "DEHP" based PVC, a wouldn't they be a manufacturer that would know this information, as in they would know the specifics of the product they're selling? and b Couldn't factory x purchased DOP based PVC sheeting from factory Y for a specific job, but ultimately, aren't they any reputable manufacturers that can use this kind of PVC from the get go without such mucking around.
I'm just starting to have my doubts about this sourcing company as I also specified in the brief that the inflatables were for therapy, in relation to a blind persons extra sensory ability for feel, so the softness of the DOP was the primary requirement. This was to avoid the looner stuff as it would have been awkward.
I'll email him on monday that the health concerns of DOP are rather questionable as such plasticizers are used for blood bags in hospitals. I'll reiterate my requirements, and see what he'll do, hopefully he'll follow up my particular specifications with another manufacturer.
