The Long Goodbye to DEHP-plasticized PVC | mddionline.com
The idea of scrapping the use of polyvinylchloride (PVC) materials containing di (2-ethylhexyl)phthalate (DEHP) plasticizers is not new. However, despite such endeavors, both PVC and DEHP plasticizer still abound in a variety of products, including garden hoses, building materials, toys, and such medical devices as, catheters, feeding tubes, and IV sets.
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Hallstar esters provide improvement for a range of parameters including: low temperature flexibility, volatility resistance, extraction and migration resistance. Products are available in both liquid as well as dry liquid concentrate form for easier handling and improved dispersion. We strive to stay ahead of market trends and new polymer launches.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Plasticizers – Benefits, Trends, Health, and Environmental
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.
Selection of Solid-State Plasticizers as Processing Aids
The objective of the study was to select solid-state plasticizers for hot-melt extrusion (HME) process. The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to asses
- What are the different types of phthalate plasticizers?
- Among them, the most common are: Phthalate Esters – Produced by esterification of phthalic anhydride or phthalic acid. Obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer
- Which phthalate is used as a plasticizer for PVC?
- DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
- Are phthalate plasticizers safe?
- Phthalate plasticizers are widely used in vinyl-based building materials. These include floorings and wall coverings. They provide them with flexibility and durability. The risk assessment results show that DINP and DIDP pose no risk to human health or the environment in any of their current applications.
- Which phthalates are banned?
- For example: DEHP -the world’s most widely used plasticizer that has been banned. Certain other high-volume phthalates including DINP and DIDP have been fully approved for use in all their current applications.
- What is phthalate plasticizer used for?
- Supply: The worldwide plasticizer market is quite large, with over 7 million tons per year. There’s not enough manufacturing capacity to produce large volumes of phthalate replacements. In electrical and electronic applications, they are used for insulating wires and cables. Phthalate plasticizers are widely used in vinyl-based building materials.
- Are phthalate plasticizers legal in California?
- There are also federal regulations (not laws) for plasticizers. On a state level, certain phthalate plasticizers are California Proposition 65 listed. This listing means that a chemical “is known by the State of California to cause cancer, birth defects or reproductive harm”.
