5 wt% Dioctyl Phthalate Plasticizer and Flow Modifier in PVC Extrusion is supplied as a high-purity formulation, specifically engineered to enhance the workability and mechanical performance of polyvinyl chloride (PVC) during extrusion processes. Offered under CAS number , this product is available in industrial and pharmaceutical grades and is currently in stock for prompt bulk supply. It provides consistent performance advantages in PVC extrusion lines, facilitating excellent plasticization and flow properties essential for high-throughput and continuous manufacturing environments.
Chemically, this product is a precisely formulated blend containing 5 wt% dioctyl phthalate (DOP) used as a plasticizer within a PVC matrix. DOP, chemically known as bis(2-ethylhexyl) phthalate, incorporates ester functional groups resulting from the phthalic acid backbone esterified with 2-ethylhexanol. The molecular formula is , and the typical molecular weight is . Structurally, its hydrophobic alkyl chains and aromatic core impart flexibility to PVC by decreasing its glass transition temperature. DOP displays moderate chemical stability and compatibility with various PVC copolymers, making it a benchmark plasticizer in numerous polymer processing applications. The product’s utility as a flow modifier directly relates to its capacity to optimize melt viscosity in extrusion, supporting both batch and continuous production workflows.
The physical characteristics of this plasticizer blend are carefully controlled to ensure batch-to-batch consistency. It has a density of , a boiling point of , and a melting point of . The assay purity is maintained at , guaranteeing minimal impurity content, while the water content is strictly limited to . For process safety, the flash point is recorded at , and logP is . The appearance is described as , which provides ease of handling during blending and extrusion stages.
The principal application for this material is as a plasticizer and flow modifier in PVC extrusion processes. Its inclusion at a 5 wt% concentration yields significant improvements in extrusion flow behavior and finished material flexibility. By lowering the viscosity of the PVC melt, this product enhances process throughput, reduces energy consumption, and enables finer control over product geometry in both single- and twin-screw extruders. Beyond its core use, it is also suitable for manufacturing flexible PVC films, cables, and medical device tubing where controlled plasticization is vital. It finds further adoption as a performance additive in flow chemistry and continuous manufacturing settings, where precise rheological control drives product uniformity. Additionally, it may serve as a standard reference plasticizer in quality assurance laboratories validating PVC formulation properties.
For logistical considerations, the 5 wt% Dioctyl Phthalate Plasticizer and Flow Modifier is packaged in sealed 25kg high-density polyethylene (HDPE) drums, each equipped with a nitrogen-purged headspace to mitigate contamination and oxidative degradation. The product should be stored in a cool, dry, and well-ventilated facility, away from direct sunlight and strong oxidizing agents. Under recommended storage conditions, the blend maintains its specification-compliant shelf life for up to 24 months. Comprehensive certificates of analysis (COA) and supporting technical documentation are provided with each batch to ensure traceability and regulatory compliance.
