Phthalates

What specific data should staff consider when deciding whether to recommend that the Commission make a determination?

How can staff be assured that a material, regardless of its origin, manufacturing process, potential for contamination or any other factor, would continue to comply with the phthalates limit indefinitely into the future as the material continues to be produced?


COMMISSION5

Phthalates

What kind of follow-up activities should be required to assure continued compliance of a material?

What other technical, practical, or implementation issues should CPSC staff consider before possibly making recommendations to the Commission regarding phthalates determinations?

What materials would provide the greatest cost savings if the Commission made a determination that the material did not contain the prohibited phthalates above 0.1 percent? Why?


COMMISSION6

Materials that may contain phthalates

What materials should always require third party testing because of potential phthalate content above 0.1 percent? Why?

What specific data or other information should be sufficient to characterize a material as potentially containing one or more of the prohibited phthalates, and thus, always require third party testing for compliance to the phthalates limit?

Workshop Goals

Identify what material specific exemptions can be determined to reduce testing based validation · Phthalates, Lead, and 8 Soluble HMs

Consider· Intrinsic material characteristics· Manufacturing, processing, downstream use

Compliance should not be compromised

Provide tangible saving in testing cost

32

Phthalates

Phthalates: Suspect list exists vinyl and vinyl like soft plastics· Create a Positive List for exempt

plastics/materials

Plastics commonly used in consumer applications* PE 33 % PP 21 % PS 8 % PVC17 % ABS< 10%

* Plastics Europe: MRG Report

Other Plastics: Not common for consumer productsPOM automotive and consumer electronicsPBT electrical housings, automotive plugs, showerheadsPC electronics, construction, aerospacePLA medical implants, biodegradable PPS electrical insulation, specialty membranes

A look at the empirical data....

Test data for phthalates · 10, 400 data points· Plastics data represents 60 -70 of the total data points

· The bill of materials is not provided

34

Testing Lab perspective ....

Lab data for phthalates

· Data is not granular to provide specific polymers that can be considered categorically for exemption

· Across all the plastic and rubber like materials, high compliance rate with the limits, approx 95%

· The difference in fail and positive detection (above DL) ≈ 1000 data points (for plastics and rubber)

· This alludes to possible contamination issue· Mixing of polymers intended or otherwise

35

Phthalates

Technical/Practical considerations determination of a positive list· Bill of materials from upstream supplier: guarantee letter· Exemption based on material properties that change pure

polymers with addition of plasticizer – Shore hardness known potential issues– Glass transition temperature not fully examined in scientific

literature

Opportunities to Reduce Third Party Testing Costs for the Plastics Industry

Consumer Product Safety CommissionApril 3, 2014

Founded in 1937, SPI is the only U.S. trade association representing all segments of the plastics industry.

MISCONCEPTION: All plastic materials used in children’s products must be tested to ensure compliance with phthalate limits.

REALITY: • The restricted ortho-phthalate plasticizers may be intentionally added to flexible

polyvinyl chloride, polyvinylidene chloride, chlorinated polyvinyl chloride and thermoset polyurethanes to make these materials flexible.

• The restricted ortho-phthalate plasticizers will NOT be added to rigid plastic materials (Shore “A” Hardness ≥ 90), nor will they be present in these materials as contaminants at levels higher than 1000ppm.

• The restricted ortho-phthalates are incompatible with many plastic materials (e.g., styrenics, polyolefins), and these materials are made flexible by other means.

May contain phthalates > 1000ppm Will not contain phthalates > 1000ppm

Plastic Materials that May be Excluded from Testing

• Rigid plastics with Shore “A” Hardness ≥90• Acetal/polyoxymethylene (POM) homopolymer • 1,3,5-trioxane, copolymer with 1,3-dioxolane

(acetal/polyoxymethylene (POM) copolymer) • Acrylic (polymethylmethacrylate and polyacrylonitrile) • Acrylonitrile butadiene styrene terpolymers (ABS) • Butadiene-ethylene resins • Butene-ethylene copolymers • Ethylene copolymers • Ethylene acrylic acid copolymers • Ethylene-propylene copolymers • Ethylene vinyl acetate copolymers • Ethylene vinyl acetate vinyl alcohol copolymers • Ethylene vinyl alcohol copolymers • Ionomers • Liquid crystal polymers (hydroxybenzoic acid copolymers) • Nylon/polyamide • Olefin thermoplastic elastomers (such as EPDM) • Polybutene

Plastic Materials that May be Excluded from Testing

• Polybutylene terephthalate • Polycarbonate • Polyesters • Polyethylene (LLDPE, LDPE, MDPE, HDPE and UHMWPE) • Polyethylene terephthalate • Polylactic acid • Polyphenylene sulfide • Polypropylene • Polystyrene • Polytetramethylene glycol-dimethyl terephthalate-1,4-

butanediol copolymer (polyester elastomer) • Propylene-ethylene copolymers • Silicone rubber (pure) • Styrene-butadiene copolymers • Styrene-butadiene-styrene rubbers (SBS/SBR) • Styrene-acrylonitrile copolymers (SAN) • Vinylidene chloride/methyl acrylate copolymers • CMYK Process Inks

MISCONCEPTION: Cross-contamination may lead to the unintentional presence of phthalates in excess of 1000ppm in a variety of plastic products.

REALITY: Manufacturers have strong incentives to avoid cross-contamination of rigid plastics with phthalates or with flexible PVC that may contain phthalates.

Destruction of resin

Off-gassing from chemical reaction

Corrosion of equipment

Facility evacuation

Poor technical performance

SPI’s Recommendation to Reduce Testing Costs

SPI respectfully requests that the Commission:

• Specify that rigid plastic materials with Shore “A” Hardness of 90 or greater will not contain the restricted phthalates in excess of specified limits.

• Publicly identify the many types of plastic materials that are known not to contain the restricted phthalates in excess of specified limits.

Thank you!

Who Is FJATA?

We make and sell jewelry.

• About 225 companies• Mostly small

businesses• Led drafting of

Children’s Jewelry Standard (ASTM F2923-11) and Adult Jewelry Standard (ASTM F2999-13)

• Leading process to update both standards

Phthalates Testing Requirements & the Marketplace

• Jewelry items are not toys• The distribution chain has

begun imposing testing requirements that match CPSC’s, even for products that do not require such testing

• Testing is a significant added burden for jewelry items

• Component testing multiplies test costs

Rigid Plastics Will Not Contain Phthalates

• When phthalates are present, they are added intentionally in amounts far about the trace levels that CPSIA bans

• The limited available data from FJATA member tests shows phthalates either not present or present in levels under 25% of the maximum in tested rigid plastics

CPSC Rule Needed toEliminate Unnecessary Test Costs

• Rigid plastics – materials with a Shore “A” Hardness rating 90 or above - will not contain phthalates.

• In fact, most plastics will not contain phthalates

• Technical data supports, with a high degree of assurance, that these materials will not contain phthalates and CPSC should issue a rule recognizing exclusions from phthalates testing

Thank you!
