PSG HAS UPDATED INFORMATION REGARDING PROP 65
It is important to note that the following information applies to PSG's family of Sizzle resins only.
As everyone in Plastics is probably aware by now, California has once again changed their requirements for labeling. After reviewing the criteria, PSG has determined with the help of knowledgeable authorities, that we can make this statement regarding our Sizzle (polystyrene) material:
PSG California Proposition 65 Statement
Proposition 65 is a Safe Drinking Water and Toxic Enforcement Act of 1986 which is a California law that requires the state to create a list of substances that is believed to have toxicological
characteristics.
Merely because a product is a listed substance does not mean that a product is in violation of any product safety requirements or standards.
In April of 2016, styrene was added to the California Prop 65 list. However, let's not confuse
styrene with polystyrene (foam). Styrene is a precursor chemical structure used as a building block to manufacture many materials, such as polystyrene (foam). In June 2011, the National Institute of Environmental Health Sciences (NIEHS) noted that styrene should not be confused with polystyrene (foam). Styrene, which is a liquid, is used to make polystyrene (foam) into a solid plastic. Finished plastics such as polystyrene (foam), ABS and SAN are not the same chemical as styrene and the Prop 65 listing does not apply to these polymers.
Polystyrene (foam) is a type of plastic that is used to make a variety of consumer finished goods.
Styrene and Polystyrene (foam) are different substances with different characteristics. FDA has
approved polystyrene (foam) as safe for use in contact with food, for more than 50 years.
PSG's Sizzle grades are an improved general purpose polystyrene and not to be confused or
categorized as styrene. Therefore, the labels are not applicable with our Sizzle grades.
An XPSA article dated May 20, 2016, the deputy director of OEHHA made it clear that one
styrene-based plastic product that will not need a label under the California Proposition 65 ruling is polystyrene. "We clearly stated this does not cover polystyrene," said Sam Delson. In 2011 and again in 2014 National Toxicology Program (NTP) reviewed, updated and reconfirmed the safety of polystyrene (foam) for use in contact with food.
John Bucher NTP Associate Director was quoted in the Associated Press in August 2011 stated: "The risks, in my estimation, from polystyrene (foam) are not very great." "It's not worth being
concerned about." A.) Styrene - OEHHA proposed a no significant risk level (NSRL) of 27 micrograms per day B.) Polystyrene (foam) - Exposure content: 6.6 micrograms per day - below safety limit.
