The MAXDIP® range is a range of special polymer compounds developed for use with waxy crude and acts as a wax crystal modifier. It prevents the growth of inter-locking wax crystals and enables oil to be pumped below its normal pour point. It is soluble in crude oil and common aromatic solvents. It has no adverse effect on the quality of resultant distillate and residues. These are being manufactured in-house with dedicated state of art manufacturing facilities.

Thermax manufactures different kinds of pour point depressants:
  • Poly alkyl acrylate/poly alkyl methacrylate
  • Poly styrene alkyl maleate
Using in-house technology Thermax is able to modify polymers depending upon needs. For various applications Thermax developed different varieties, by varying alkyl groups, combinations of acrylate & methacrylate back bone, different molecular weights, varying solvents, co-polymers with synergistic co-monomers, derivatives with amine compounds, formulation of two separately prepared polymers as so on. Thermax has also developed some surfactants, which can be formulated with pour point depressants in order to combat Asphaltenes presents in crude oil.

Performance of PPD depends upon the wax content and nature of wax present and also on the presence of asphaltenes & resins. Hence for a particular oil one has to conduct a bottle test on the field with variety of chemicals before suggesting a specific chemical & dosage depending upon the specific requirements of the field. In order to cater for range of oils, Thermax has already developed more than 22 polymers of above types. Thermax has been a consistent supplier of different grades of PPD Globally.
