DINP Plasticizer

Diisononyl Phthalate (DINP Plasticizer) is a colorless, oily liquid primarily composed of phthalate esters. It is derived from the esterification of isononyl alcohol and phthalic acid. The chemical structure of DINP includes two long alkyl chains, which contribute to its high flexibility as a plasticizer for polyvinyl chloride (PVC) and other plastics.

What is DINP Plasticizer?

Dioctyl Isononyl Phthalate (DINP) is a widely used industrial plasticizer designed to enhance the flexibility, durability, and long-term performance of polyvinyl chloride (PVC) products. It is a clear, colorless, oily liquid with excellent chemical stability, making it a preferred choice in various demanding industrial applications.

DINP is characterized by its low volatility, high resistance to water, and excellent resistance to extraction under extreme conditions. It also maintains exceptional flexibility and durability at both high and low temperatures, making it suitable for specialized environments that require performance under extreme thermal conditions. This robust performance ensures reliable functionality in demanding applications across different industries.

DINP is widely applied in the manufacturing of flexible PVC products such as cables, flooring materials, automotive parts, and synthetic leather. Its compatibility with PVC and other resins without compromising mechanical properties has established DINP as a superior choice for manufacturers requiring high-quality, durable plastic materials that can withstand a wide range of temperatures.

Comparison of DINP and DOP

Property DINP DOP
Chemical Composition DINP is a non-phthalate plasticizer based on isononyl alcohol, offering improved thermal stability and lower volatility compared to DOP. DOP is a phthalate-based plasticizer, widely used but under scrutiny for its environmental and health risks.
Environmental & Health Impact DINP is considered to have a lower environmental impact and health risks compared to traditional phthalates. DOP may pose health risks, including carcinogenicity, leading to regulatory restrictions.
Performance & Durability DINP can be used in extremely low and high temperatures, making it suitable for specialized environments with demanding conditions. DOP is less resistant to high temperatures and aging compared to DINP.
Applications DINP is commonly used in flexible PVC products, including flooring, cables, and coatings, as well as automotive applications. DOP is widely used in PVC resins, synthetic fibers, and paints, but faces increasing regulatory restrictions.

FAQ

DINP offers superior performance in extreme temperature conditions. It maintains its flexibility and durability even in high and low temperatures, making it suitable for specialized applications that require resilience in harsh thermal environments. It is also less volatile and more resistant to water and extraction under extreme conditions compared to other plasticizers.

DINP is primarily used in industrial applications and is not typically used in food or medical products. For applications that involve direct contact with food or medical devices, other plasticizers that meet specific regulatory requirements may be preferred.

DINP provides excellent flexibility, durability, and long-term performance in PVC products. It enhances the material’s resistance to aging, cracking, and weathering, making it ideal for use in applications such as cables, flooring, and automotive parts.
