⭐ What Is DOTP (Dioctyl Terephthalate)?

DOTP is a modern, environmentally friendly, non-phthalate plasticizer.
It is used to give PVC and other polymers flexibility, durability, and high performance.

Compared to classic plasticizers such as DOP and DINP, DOTP is safer, odorless, and more environmentally compatible, which is why it is widely preferred today.

🔧 What Is DOTP Used For?

The purpose of DOTP is to soften PVC and other polymers, increase flexibility, and improve durability.

Key properties it provides:

• Excellent flexibility and elasticity
• High heat and UV resistance
• Low volatility (does not lose plasticizing effect over time)
• Great resistance to abrasion and cracking
• Stable and controlled flow during processing

DOTP is a longer-lasting and lower-odor alternative to DOP.

🎯 Purposes of DOTP

✔ 1. To provide a safer and more environmentally friendly plasticizer

It is preferred for health and regulatory reasons because it contains no phthalates.

✔ 2. To improve flexibility and durability of products

Ideal for applications requiring high mechanical performance.

✔ 3. To increase product lifetime

Thanks to its low volatility, it does not harden or crack over time.

✔ 4. To ensure high-quality surface finish

Provides smooth, glossy, and consistent surfaces in PVC products.

✔ 5. To improve processing performance

Stable performance in extrusion, injection, and calendaring operations.
