Diisononyl phthalate (DINP for short) is a transparent oily liquid with a slight odor. This product is a general-purpose main plasticizer with excellent performance. This product has good compatibility with PVC, and will not precipitate even if it is used in large quantities; its volatility, migration and non-toxicity are better than DOP, and it can endow the product with good light resistance, heat resistance, aging resistance and electrical insulation properties, and its comprehensive performance is better than that of DOP. DOP. Because the products produced by diisononyl phthalate have good water resistance and extraction resistance, low toxicity, aging resistance and excellent electrical insulation properties, they are widely used in various soft and hard plastic products, toy films, wires and cables.



Recall According to the recall management procedure, recalls are classified into 3 levels (level 1, level 2 and level 3). The timelines of authority and client notification are defined as within 24 hours, 48 hours and 72hours, respectively.


Gentolex provide great quality products, if any product quality is raised by the client within the required time frame with sufficient evidences, we will provide necessary analysis and evaluation to trigger the procedures of compensations.


The capacities of pharmaceutical products reached tons grade, the capacities of chemical products reach 100tons+ grade, the capabilities are well equipped to serve clients worldwide.

Research and Development

Every year, there is plan set up by the R&D team to develop different new products, when targets set, every member in the team will have to carry on with KPI responsibility and with incentive policy.
