Is TPU safe for Mattress and Pillow protectors 04 Sep 2014 17:28 #1

Hello!

Below is the information supplied by Gotcha Covered for the waterproof TPU material in their pillow protectors and mattress protectors.
Can you please tell me whether it's safe to sleep on? Thank you!

THERMAL POLYURETHANE (TPU) INFORMATION

· TPU is a micro-thin layer of film that is laminated onto the underside of the protector. Many washable waterproof products typically use polyvinyl chloride (PVC) which make them environmentally unfriendly.


· The TPU film comes from blown extrusion process which uses less energy to produce, compared to PVC. The TPU lamination process uses less energy to manufacture, creates less pollution, and is easier to dispose of at waste treatment plants than standard PVC.


· TPU contains NO plasticizers (phthalates) making it environmentally friendly, unlike PVC which leaches out of formulations, potentially contaminating soil and groundwater.



· TPU is softer and weighs less than the traditional PVC, which means it costs less to ship as well as launder.

· There are no off gases produced by the TPU film when used below the decomposition temperature. The decomposition temperature for this TPU membrane used is 482oF (250o C).

It is the cleanest burning membrane which only generates CO2 and water when incinerated and is free of volatile organic compounds (VOCs).

The base resin used in this grade of polyether polyurethane membrane passes USP Class VI testing for medical applications, is listed under NSF61 for potable water applications, and complies with FDA regulatory standards 21 CFR 177.1680 and 177.2600, and therefore can be used for applications which have direct and indirect food contact.


Osmosis creates “breathability” by moving moisture vapor from one side to the other.


It does have some industrial recycled material in it (5 % max > more won’t allow for a soft film at 1ml).

Hi NeedYourHelp,

I think the short answer would be that IMO I would consider it to be completely non toxic and very safe yes.

While it's probably beyond the level of research that most people would want to become involved in and I don't think that most people would consider any of the materials used in any of the breathable or semi breathable mattress protectors to be harmful ... there is a little more information about the different types of membranes in the last part of post #2 here and some of the information sources it links to.
