PET

Some information on PET (PolyEthylene Terephthalate)

PET in its natural state is a colorless, semi-crystalline resin. Based on how it is processed, PET can be semi-rigid to rigid, and it is very lightweight. It makes a good gas and fair moisture barrier, as well as a good barrier to alcohol (requires additional "barrier" treatment) and solvents. It is strong and impact-resistant. PET becomes white when exposed to chloroform and also certain other chemicals such as toluene.

PET is a food grade plastic!

PET Safety Information:

Chronic/Carcinogenicity: None of the components present in this material are listed as a carcinogen. Under normal processing conditions, this product contains no toxic chemicals.

Inhalation: PET is not expected to be an inhalation hazard under normal processing conditions. Normal processing does not include degradation that can happen when overheated.

Molten plastic: Can cause severe thermal burns.

Fumes: Fumes produced during the melting processing, do not present any hazards or toxins.

Secondary Operations: Grinding, sanding, or sawing, can product dust which may present a respiratory hazard.


1st Aid:

Inhalation: Seek fresh air; seek medical attention if difficulties in breathing occur.

Skin: If skin has contact with molten material, place affected area under cold running water. Seek medical attention for removal of material from the affected area.

Eyes: If there is contact to the eyes with molten material, rinse with plenty of water and seek immediate medical attention. If fines enter the eye, rinse with water for 15 minutes and seek immediate medical attention if irritation develops.

Medical Restrictions: Certain sensitive individuals and individuals with respiratory impairments may be affected by exposure to components in the processing fumes/dust.
