4 Pch Carpeting

There is no known human health risk associated with this compound.
4 pch carpeting. 4 phenylcyclohexene or 4 pch is a by product formed during the polymerization process of styrene butadiene latex that is used in carpet backing. A byproduct of the rubber 4 pch is a voc that causes the distinctive new carpet smell. It s also what could make you sick. Sb latex is used in carpet construction to adhere the face fibers and the backing materials.
The maximum emissions limits for these are as follows. 4 pch can linger after installation for up to a week exposing the homeowner to the pungent odor. Reports suggest that exposure to very low levels of 4 pch or other emission products following new carpet installation may result in health complaints. 4 phenylcyclohexene 4 pch is a by product formed during the polymerization of styrene butadiene latex used in carpet backing.
This is a compound responsible for new carpet smell. Subsequently the concentrations of alkenes such as styrene 4 vch and 4 pch in the carpet emissions fall. 4 pch and other volatile carpet compounds react with ozone o3 at levels often found in indoor air to produce formaldehyde hcho and c5 c10 aldehydes. 1000 µg m hour for tvocs 300 µg m hour for bht 50 µg m hour for formaldehyde 50 µg m hour for 4 pch.
Slowly but steadily the chemicals in the carpeting and stain treatment product evaporate into the air you breathe becoming a significant source of indoor air pollution. Green label and green label plus are independent product certification programs run by the carpet and rug institute cri. Samples of two carpets. Limited reports suggest that exposure to very low levels of 4 pch or other emission products following new carpet installation may result in health complaints.
All bentley products meet the green label plus program s testing requirements which ensure the level of 4 pch is in trace quantities. Carpeting has traditionally been smelly because of the 4 phenylcyclohexene 4 pch an unintended low level by product of the chemical polymerization process that creates styrene butadene sb latex. The 4 pch is what emits new carpet smell. The new carpet odor that people usually smell is a voc called 4 phenylcyclohexene 4 pch which is a byproduct of the latex binder used to secure the tufted fibers to the backing.
