Description

Product Introduction

Dioctyl Terephthalate, an organic compound with the molecular formula C ₂₄ H ₃₈ O ₄ , is a transparent oily liquid insoluble in water, and serves as an excellent primary plasticizer commonly used in polyvinyl chloride (PVC) plastics, featuring advantages such as heat resistance, cold resistance and low volatility.

Product Application

(1) It can be used in the production of PVC products such as wires and cables, pipes, plates, and films, improving the flexibility, heat resistance, and cold resistance of the products.

(2) In the automotive industry, it is suitable for making automotive interior parts, sealing strips, etc., meeting the requirements for material performance.

(3) It can also be used in the production of plastic components for medical devices, toys and other products, complying with relevant safety standards.

(4) It is applied in the manufacturing of floor coverings and wall panels, enhancing the durability and wear resistance of these PVC-based products.

(5) It can be used in the production of plastic hoses and profiles, ensuring they maintain good mechanical properties under different environmental conditions.

Product Function

(1) Enhancing plastic flexibility: It can weaken the force between polymer molecules, making hard and brittle plastics (such as PVC) soft and easy to process, and convenient for making products of various shapes.

(2) Improving weather resistance: It enhances the heat resistance and cold resistance of plastics, enabling products to maintain stable physical properties in high or low temperature environments, and not easy to harden or crack.

(3) Strengthening durability: It improves the anti-aging and impact resistance of plastics, prolonging the service life of products, which is especially suitable for products that need to be used for a long time (such as pipes, cables, etc.).

(4) Ensuring processability: During plastic processing, it can reduce melt viscosity, improve fluidity, and facilitate molding through processes such as extrusion and injection molding.
