Dioctyl terephthalate (DOTP) is an advanced plasticizer. Compared with traditional diisooctyl phthalate (DOP), DOTP exhibits better heat resistance and low-temperature flexibility, low volatility and excellent electrical insulation, making it a better choice for PVC and other polymer products.

Properties and Usage:

The main advantage

1. Low volatility: The volatility of DOTP is much lower than traditional plasticizers, which makes it more stable in high-temperature applications, especially suitable for wire and cable products.

2. More environmentally friendly: Due to its excellent chemical stability and low migration, DOTP has less impact on the environment and is more in line with modern environmental standards.

3. Suitable for more temperature ranges: Under low temperature conditions, the product is more flexible than other plasticizers.

4. Electrical insulation properties: Ideal material for manufacturing cables and wires, especially in applications that require compliance with IEC International Electrotechnical Commission standards.

Application areas

1. Cables and wires: DOTP meets the cable industry’s demand for high safety standards due to its temperature resistance, low volatility and insulation properties.

2. PVC products: In soft polyvinyl chloride products, such as floors, wallpapers, artificial leather films, etc., DOTP used as a plasticizer can significantly improve their water resistance, oil resistance and overall durability.

3. Coatings and rubber: As a plasticizer and coating additive, DOTP can improve the flexibility and weather resistance of coatings

4. Paper processing: As a softener for paper, it improves the feel and strength of paper.

Storage and transportation:

The product should be kept away from light and should be protected from impact, fire, sun and rain during transportation. The product should be stored in a dry, ventilated warehouse, away from heat and fire.

Packaging specifications:

Net weight 200kg/drum,or customized packaging according to customer requirements.
