California Proposition 65 Information

Quick Answer

California Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a state law designed to protect California's drinking water sources from contamination by chemicals known to cause cancer, birth defects, or other reproductive harm. It mandates that businesses, including suppliers and distributors like Industrial Plastic Supply, Inc., provide clear and reasonable warnings to Californians about potential exposures to such listed chemicals in their products. This regulation specifically impacts the plastics industry by requiring disclosure of chemicals found in various plastic materials, such as certain phthalates or carbon black, that are identified as hazardous under Prop 65.

Proposition 65

Proposition 65 is also known as the Safe Drinking Water and Toxic Enforcement Act of 1986.  Prop 65 protects the state’s drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals.

According to Proposition 65, suppliers and distributors of a product and retail sellers need to provide a clear and reasonable warning for all product that may expose the consumer to any of the listed substances.

Here is a list of chemicals known to the state to cause cancer or reproductive toxicity.

What are the Frequently Asked Questions about California Proposition 65 and Plastic Materials?

1 What is California Proposition 65?

California Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, protects California's drinking water sources from contamination with chemicals known to cause cancer, birth defects, or other reproductive harm. It requires businesses to provide clear and reasonable warnings before knowingly exposing anyone to listed chemicals. The full list of chemicals is maintained by the California Office of Environmental Health Hazard Assessment (OEHHA) at oehha.ca.gov.

2 Which plastic materials stocked by Industrial Plastic Supply have no Prop 65 chemicals?

The following materials stocked by Industrial Plastic Supply have no listed Prop 65 chemicals for either cancer or reproductive harm: Cast Acrylic, HDPE Natural, HDPE Colored Starboard/Marine, HDPE Black Starboard/Marine, Kynar Natural (PVDF), PEEK Natural, PETG Vivak, PVC Type 1, PVC Type 2, PVC Clear (LAM 2000), PVC CRP-1, PVDF (Simona), Rexolite, and UHMW Natural.

3 Do Polycarbonate plastics contain Prop 65 chemicals?

Yes. All Polycarbonate grades stocked by Industrial Plastic Supply — including glazing sheet, clear, and black — contain Bisphenol A (BPA), which is listed under Prop 65 as a reproductive toxin. Black Polycarbonate also contains Carbon black, which is listed as a cancer-causing substance under Prop 65. SDS source: Plaskolite.

4 Do Acetal and Delrin contain Prop 65 chemicals?

Yes. Both Acetal Copolymer (natural and black) and Delrin Homopolymer (FDA colors) contain Acrylamide, Ethylene Oxide, and Formaldehyde — all listed under Prop 65 for both cancer and reproductive harm. Delrin Black Homopolymer contains Carbon black (cancer). Delrin AF Natural (brown) contains Formaldehyde (both cancer and reproductive harm). SDS source: Ensinger.

5 Does PTFE (Teflon) have any Prop 65 warnings?

Yes. PTFE (Polytetrafluoroethylene) stocked by Industrial Plastic Supply carries a Prop 65 reproductive harm warning for Carbon Monoxide (CAS 630-08-0) and a cancer warning for Tetrafluoroethylene (CAS 116-15-4). SDS source: Enflo.

6 Does Ultem PEI have any Prop 65 chemicals?

Yes. Ultem PEI contains Bisphenol A (BPA), which is listed under Prop 65 as a reproductive toxin (birth defects). No cancer-causing chemicals are listed for Ultem. SDS source: Ensinger.

7 Where can I find the full list of California Prop 65 chemicals?

The full and current list of chemicals known to the State of California to cause cancer or reproductive toxicity is maintained by the California Office of Environmental Health Hazard Assessment (OEHHA) and is available at https://oehha.ca.gov/proposition-65/proposition-65-list.
