ChemFlexx DPHP

ChemFlexx DPHP is a versatile, high-performing plasticizer designed to deliver consistent plasticization across a wide range of vinyl and polymer formulations. Its isometric C10 alcohol-based structure supports flexibility while maintaining resistance to degradation under mechanical, thermal, and environmental stress.

High phthalate products such as dipropylheptyl phthalate (DPHP) are used as alternative PVC plasticizers developed to meet modern regulatory and performance expectations. ChemFlexx DPHP is widely adopted as a replacement for previously classified plasticizers, including DOP, in applications where long service life and durability are required.

ChemFlexx DPHP is often selected as a general-purpose plasticizer due to its versatility and ease of substitution into existing formulations, typically requiring minimal processing adjustments. Its resistance to extraction, evaporation, and migration contributes to extended product lifetime and consistent performance. In applications where even lower volatility or higher heat resistance is required, ChemFlexx TOTM may be considered.

Density

Compared with other plasticizers, ChemFlexx DPHP offers a lower density that may be advantageous in applications where overall weight reduction is important. Lower density can translate into increased output by volume in finished PVC articles and foil products. In screw processing applications, its bulk properties support higher production output and reduced torque.

Volatility

ChemFlexx DPHP demonstrates low volatility at elevated temperatures. In high-temperature applications, this permanence helps limit migration, supports long-term durability, and reduces waste generation associated with material degradation.
