Diethylhexyl phthalate (DEHP) is a widely used plasticizer. It is also known as di-2-ethylhexyl phthalate, DEHP, or DOP. It is used to make plastics more flexible, resilient, and long-lasting. Common applications for DEHP include flooring, furniture, medical tubing, gloves, and other products that require flexibility.
When exposed to DEHP, rubber materials can experience swelling and softening, leading to weakening of the parts and subsequent failure. In addition, DEHP can cause corrosion of metal components, which can lead to cracking, leaks, and other kinds of damage. This can be particularly true when DEHP is used in combination with other chemicals, such as fuels and lubricants. In such cases, the rubber may not be able to withstand the combined effects of the chemicals, resulting in premature failure.
