中文简体Tri-2-ethylhexyl trimellitate (TOTM) is a specialized plasticizer known for certain key properties that make it suitable for specific applications. Here are the key properties of TOTM:
High Temperature Stability:
One of the primary advantages of TOTM is its exceptional heat stability. TOTM can withstand high temperatures without undergoing significant degradation or loss of performance. This property makes it particularly suitable for applications where exposure to elevated temperatures is a concern.
Low Volatility:
TOTM exhibits low volatility, meaning it has a low tendency to evaporate or migrate from the polymer matrix over time. This characteristic contributes to the long-term stability and durability of materials containing TOTM, especially in applications where low volatility is critical.
Low Migration:
TOTM has low migration tendencies, which is important in applications where the plasticizer needs to remain within the polymer matrix without leaching out. Low migration is particularly advantageous in applications where material stability and consistency are crucial, such as in medical devices and certain consumer products.
Excellent Electrical Properties:
TOTM is often used in applications that require excellent electrical properties. Its use in wire and cable insulation, for example, benefits from TOTM's ability to provide flexibility to the polymer without compromising electrical performance.
Good Extraction Resistance:
TOTM exhibits resistance to extraction by oils and various solvents. This property is valuable in applications where the plasticized material may come into contact with oils or other substances that could potentially extract the plasticizer.
Low-Temperature Flexibility:
While TOTM is renowned for its high-temperature stability, it also maintains flexibility at lower temperatures. This characteristic is essential in applications where the plasticized material needs to remain pliable and functional in a range of environmental conditions.
Chemical Resistance:
TOTM provides good chemical resistance, contributing to the durability and longevity of materials in challenging environments. This property makes it suitable for applications where exposure to chemicals or harsh substances is a consideration.
Compatibility with Various Polymers:
TOTM is compatible with a variety of polymers, including polyvinyl chloride (PVC), polyethylene, and others. This versatility allows for its use in a range of industries and applications where different polymer matrices are employed.
Low Odor and Color:
TOTM typically imparts low odor and color to the final product, making it suitable for applications where the aesthetic and sensory qualities of the material are important. This is especially relevant in consumer goods, textiles, and other industries where the appearance and smell of the final product matter.
Regulatory Compliance:
TOTM is often selected for applications where regulatory compliance is a key consideration. Its use is regulated, and it meets certain safety standards, making it suitable for industries where adherence to regulations is critical.
