Biobased Plasticizers from Tartaric Acid, an Abundantly
Esters/ethers derived from tartaric acid, an abundant renewable biomaterial, have been synthesized, fully characterized and evaluated as plasticizers in PVC. These compounds are fully...
Preparation and Performance of Bio-Based Polyol Ester
We expected that this study can provide a non-toxic and sustainable plasticizer to replace DEHP in PVC products. Experimental Materials Dioctyl phthalate (DEHP), castor oil, glycidol, methanol, acetic anhydride, chloroform, tetrahydrofuran (THF) were purchased from , China.
Nontoxic bio-plasticizers for PVC as replacements
Abstract. Stretched PVC film samples were created to compare the performance of toxic and non-toxic plasticizers. The reference films were produced with ditridecyl phthalate and trinonyl benzene-1
A Better Alternative to Phthalates? | NIST
However, phthalates can disrupt the hormonal or endocrine system, which may cause pregnancy loss, infertility and harmful effects on the delivery of a baby. As a result, many manufacturers have replaced phthalates with chemicals such as DINCH, another type of plasticizer, but less is known about the effects of this chemical compound on humans.
Chemists develop safe alternatives to phthalates used in plastics
November 1, 2018. Source: University of California - Santa Cruz. Summary: Researchers have developed safer alternatives to the phthalate plasticizers used to enhance the suppleness, flexibility
- What are alternative plasticizers for polyvinyl chloride (PVC)?
- Environmental and toxicity concerns dictate replacement of di (2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC). Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS).
- Are plasticizers phthalate-free?
- nyl phthalate (DINP).Key FindingsHBN identified six phthalate-free plasticizer types, three synthetic and three bio-based, in use i ommercial PVC building products. The available data suggest that non-phthalate plasticizers present fewer hu
- What phthalate is used in PVC plasticizers?
- The most widely used PVC plasticizers are phthalate esters, particularly di- (2-ethylhexyl) phthalate (DEHP), which usually represent up to 40–50% of the weight of the plastic items. Phthalates account for 80% of all plasticizer production while DEHP is responsible for over 50% of worldwide phthalate production .
- Are non-phthalate plasticizers effective?
- The response to the need for non-phthalate plasticizers that are effective, nonmigrating and nontoxic has focused on the development of plasticizing compounds derived from biomaterials or biobased materials [7 – 9]. Most often, these have been designed for use in PVC [10 – 12].
- Are there alternatives to phthalate plasticizers?
- CALCE has been being interested in the performance and reliability of newly alternative materials, which are aligned to the legislations, and proposed potential alternatives to phthalate plasticizers, including bio-based substitutes and thermoplastic elastomers.
- Are phthalates toxic to PVC based medical devices?
- In flexible plasticizer PVC (P-PVC), phthalates are not chemically bound to PVC and they are released into the external environment. In particular, prolonged contact of P-PVC based medical devices with body fluids or tissues has been shown to be associated with severe health risks.
