Improving Processing of PET, the World’s Most Recycled Plastic
Phthalates are low molecular weight monoesters made from orthophthalic acid. By comparison, PET is a high molecular weight polyester made from terephthalic acid and these forms are chemically very different. Phthalates (i.e. phthalate ester plasticizers) are not used in the manufacture of PET, and PET itself is not a phthalate.
Dimethyl phthalate = 99 131-11-3 - Sigma-Aldrich
Dimethyl phthalate (DMP) is a short-chained ester known as a phthalate acid ester. It is majorly used as a plasticizer for the production of polyvinyl chloride (PVC) and in the coating of cellulose films.
Method 606: Phthalate Ester - US EPA
3.2 Phthalate esters are contaminants in many products commonly found in the laboratory. It is particularly important to avoid the use of plastics because phthalates are commonly used as plasticizers and are easily extracted from plastic materials. Serious phthalate
Diisononyl Phthalate (DINP) - Chemical Supplier Distributor
1.481-1.488 Application Diisononyl Phthalate (DINP) is a general use high molecular weight PVC Plasticizer which provides a good balance of cost savings and properties. DINP is a preferred replacement for DOP plasticizer, and is highly compatible with PVC and shows good permanence.

- What are phthalate plasticizers?
- From a chemical point of view, phthalate plasticizers come from an esterification reaction between phthalic anhydride and an alcohol with specific characteristics. Phthalates are the most used molecules in many sectors of industrial production.
- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- What phthalate replacements does hallstar offer?
- Hallstar has a broad product portfolio with a wide range of functionality in both elastomers and PVC. A subset of this brand is our Plasthall® PR-Series which represents the group of products designed as phthalate replacements. Plasthall ® 114 is a proprietary, aliphatic ester plasticizer used to modify high-polarity thermoplastics and elastomers.
- What are phthalates used for?
- Phthalates are the most used molecules in many sectors of industrial production. Although their molecular structure is able to intercalate in the structure of many different polymers, plasticizers phthalates find their main use in combination to PVC, one of the most used plastic polymers in various sectors worldwide.
- Is plasthall a polymeric or monomeric plasticizer?
- Ester plasticizers are typically monomerics, but those designated as Plasthall® P-Series are polymerics. Hallstar has a broad product portfolio with a wide range of functionality in both elastomers and PVC. A subset of this brand is our Plasthall® PR-Series which represents the group of products designed as phthalate replacements.
- What is an ester plasticizer?
- An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one.
