Plasticizer Migration Study by Teknor Apex Ranks Phthalates
PAWTUCKET, RI, U.S.A., September 9, 2013: Teknor Apex Company has completed a study of plasticizer migration as it may affect non-PVC thermoplastics that are widely used for medical device components which come into contact with components made of PVC, it was announced today by the Vinyl Division.
Plasticiser Migration Study by Teknor Apex Ranks Phthalates
Teknor Apex has studied the effects of plasticiser migration into non-PVC thermoplastics in contact with plasticised PVC parts in medical devices. Result show that some plasticisers cause defects while others exhibit no effects.
Teknor Apex completes plasticizer migration study for non-PVC
The Vinyl Division of Teknor Apex has completed a study of plasticizer migration as it may affect non-PVC thermoplastics that come into contact with components made of PVC in medical devices. The study focuses on four materials commonly used in conjunction with PVC in such applications: ABS, acrylic, polycarbonate (PC) and polystyrene (PS). A

Migration test. Small squared strips of polystyrene ( 3 mm ×3 mm) with approximately 1 mm of thickness were placed between two PVC sheets of 2 mm of thickness, and kept under mild pressure (217 kPa) in a oven at 50 °C for 1 week. Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer
Migration of plasticizers phthalates, bisphenol A and
This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles. Compounds studied were phthalates (dimethyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, bis(2-ethylhexyl) phthalate), bis(2-ethylhexyl) adipate, octylphen
- Do plasticizer migration rates correlate with a child's exposure to plasticizers?
- The correlation between migration rates and plasticizer concentration is rough, and it inversely correlates with the molecular mass of the plasticizer. By combining these migration rates with data on mouthing duration, we estimated children's exposure to plasticizers in toys and child care articles, and calculated the resulting margins of exposure.
- Is diisononyl phthalate used as a plasticizer?
- Diisononyl phthalate (DINP) is used as a plasticizer in children's products made from polyvinyl chloride (PVC), such as teethers and toys. Children may be exposed to phthalates when handling or mouthing PVC products because plasticizers are not covalently bound.
- How do plasticizer migration rates correlate with molecular mass?
- The molecular mass of plasticizers inversely correlates with their migration rates. CPSC measured migration rates using the Joint Research Centre method. Migration rates correlated roughly with plasticizer concentration.
- Why are children exposed to phthalates when handling PVC products?
- Children come into contact with phthalates when handling or mouthing PVC products because phthalates are not covalently bound and can migrate from children's toys, child care articles, art materials, and school supplies.

- What is diisononyl phthalate (DINP)?
- Diisononyl phthalate (DINP) is a dialkyl phthalate plasticizer that has been used in children's products made from polyvinyl chloride (PVC), such as teethers and toys. It is one of the plasticizers that can migrate from children's toys, child care articles, art materials, and school supplies.
- Are alternative plasticizers to phthalates safe?
- Since the Consumer Product Safety Improvement Act of 2008 prohibited certain phthalates from use in child care articles and children's toys, manufacturers have turned to other plasticizers or non-PVC plastics. There is ongoing interest in evaluating the potential health risks of these alternative plasticizers.
