DINP, whose chemical name is diisononyl phthalate, is a colorless to light yellow liquid viscous.
DINP is mainly synthesized from phthalic acid and isononyl alcohol through an esterification reaction, and has good solubility and processability.
Properties and Usage:
Features:
1. Excellent plasticizing properties: DINP has good compatibility with resins such as polyvinyl chloride, high plasticizing efficiency, and has excellent heat resistance, light resistance, aging resistance and electrical insulation.
2. Good heat resistance: DINP has good stability at high temperatures, is not easy to decompose, and is suitable for various processing techniques.
3. Good compatibility: DINP has good compatibility with a variety of resins and additives, and there will be no precipitation even if used in large quantities. It can be used in conjunction with other plasticizers and additives to improve the overall performance of the product.
4. Environmental protection: DINP has low volatility, does not easily emit harmful gases, and meets environmental protection requirements.
5. Aging resistance: Because the carbon chain contained in the chemical formula is long enough, it has better migration resistance and aging resistance.
6. However, the weather resistance of this product is relatively poor.
Main application areas:
1. Plastic products: DINP is widely used in the production of polyvinyl chloride (PVC) products, synthetic rubber, plastic flooring, artificial leather, soft pipes and other plastic products.
2. Building materials: In building decoration materials such as floors and walls, DINP as a plasticizer can improve the softness and wear resistance of the materials.
3. Paints and coatings: Highly dispersible, used as dye additives.
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.
