INSPITE OF BEING PHTHALATE PLASTICIZERS, WHY DINP AND DOTP
DINP and DOTP are perfect plasticizers for replacing DOP: DINP (Di-Iso-Nonyl Phthalate) and DOTP (Di octyl terephthalate), have the same softening effect as DOP (efficiency factor 1.03). At the
An investigation of plasticisers in 21st century value chains
DOTP is a non-phthalate plasticiser but DINP is a phthalate plasticiser and in 2018, Denmark failed to persuade ECHA's Risk Assessment Committee to classify DINP as a category 1B reproductive toxicant. This was despite the Scandinavian country's earlier success in initiating restrictions for DEHP (DOP)
Inspite of being phthalate plasticizers, why dinp and dotp
In DOTP, in contrast to DOP, the ester radicals are not only branched but are additionally arranged on opposite sides, in the para position, of the benzene ring. The molecular structures of DOTP and DINP occupy more space spatially. This prevents the migration of both molecules from the material and they are not enriched in the environment.
What Is The Difference Between DOTP And DINP？ - News
Compared with DOP, DINP has a larger molecular weight and longer carbon chain, so it has better aging performance, anti-migration performance, anti-extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP is slightly worse than that of D0P.
Good Stability Plasticizer DINP Manufacturers In Turkey
Diisononyl Phthalate (DINP) - Chemical Supplier DINP is a preferred replacement for DOP plasticizer, and is highly compatible with PVC and shows good permanence. When compared to DOP, DINP has lower volatility, improved cold temperature flexibility, and better permanence in the final product.
- Is DOTP a terephthalate plasticizer?
- D.O.T.P is a terephthalate plasticizer and has a very different structure in structure as seen from its open formulas from orthoftalate esters such as D.O.P, D.I.O.P, D.I.N.P, D.I.D.P. This branched structure of D.O.T.P provides D.O.T.P many excellent features not found in other plasticizers.
- What is the difference between DOP and DOTP plasticizer?
- DOTP plasticizer: DOTP is a p-phenylene product, which meets the requirements of the European Union and can be used instead of DOP, and is an ideal substitute for DOP. Is plasticizer in plastic wrap harmful to human body?
- How to use it correctly
- What is the difference between DOTP and terephthalate?
- DOTP (Dioctyl Terephthalate): On the other hand, DOTP’s unique molecular structure, originating from terephthalic acid, provides higher heat resistance and environmental stability. This chemical variation impacts each plasticizer’s performance, especially under different conditions. 2. Comparing the Physical and Chemical Properties of DOP and DOTP
- Is DOP better than DOTP?
- When it comes to plasticizing efficiency, DOP typically outperforms DOTP in terms of flexibility. This means that DOP is often the preferred choice in applications where maximum plasticity is required, such as in flexible PVC products like flooring and artificial leather.
- What is the cold resistance of DOP plasticizer?
- DOP plasticizer: For DOP plasticizer, cold resistance is excellent, the condensation point is 4 ℃, and can be in -18 ℃ can also be normal production.
