DINP-DIISONONYL PHTHALATE

⭐ What Is DINP (Di-isononyl Phthalate)?

DINP (Di-isononyl Phthalate) is one of the most widely used phthalate-based plasticizers. It is added mainly to polyvinyl chloride (PVC) and other polymers to provide flexibility, durability, elasticity, and improved processability.

It is commonly preferred in industry as a more durable alternative to standard plasticizers.

🔧 What Is DINP Used For?

The primary function of DINP is to soften and make PVC and other polymers flexible.

Key properties it provides:

Makes PVC flexible, durable, and easy to shape

Performs excellently in long-life applications

Increases resistance to heat, UV light, and outdoor conditions

Reduces the risk of cracking, breaking, or hardening

Provides chemical stability

🎯 Purposes of DINP
✔ 1. To Provide Flexibility

Used in applications where high flexibility is required, especially in PVC (cables, floorings, etc.).

✔ 2. To Increase Durability

Ideal for producing products that must resist outdoor conditions for long periods.

✔ 3. To Provide Cost Efficiency

It is more economical than some alternative plasticizers, which makes it highly preferred.

✔ 4. To Improve Performance

Maintains elasticity in products exposed to heavy physical stress such as:

Bending

Stretching

Pressure
