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.
Bis(2-ethylhexyl) terephthalate
Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.
Comparative table of indicators of plasticizers DOP and DOTP
In this article investigates the effect of the content of plasticizers on the properties of rubbers based on rubber BNKS-18 AMN. The traditional, widely used dioctyl phthalate (DOP), as well as...
A Comparison of Plasticizers for Use in Flexible Vinyl
Table I. Performance of plasticizers compounded to a standard modulus (0.5-mm film). Study 2 took a different approach, holding the amount of plasticizer in the compound constant for all plasticizer types and allowing the hardness and modulus to vary. 2 The ingredients were mixed and then placed on a two-roll mill for 5 to10 minutes at 163°–171°C.
Learn more about PVC Plasticizers - DOP and DOTP
Normally, DOP tends to be the cheapest PVC plasticizer, mainly due to the economies of scale achieved by this material, which means that its offer is greater than DOTP. In Plastisol, DOP is preferred because it does not generate so many “pin holes” defects because it doesn’t affect viscosity, allowing volatile substances to leave the paste.
