Product Use
-
Electrical · Electronic Insulation
Electrical and electronic insulating materials prevent the flow of electrical charges and prevent the transmission of electric fields. It is used when mixed with other compounds to form insulators or insulating coatings. These mixtures provide electrical and thermal stability, improving equipment safety and performance. -
Rubber Synthesis
HHPA is mainly used in the synthesis of nitrated rubber and polyamide, which contributes to improving the thermal stability and mechanical strength of rubber. MA is used in the manufacture of acrylic rubber and embedded rubber, which are used in a variety of industries due to their high viscosity and durability. -
High Functional Materials
HHPA is used as an important intermediate in polymer synthesis. It is used to form various forms of thermosetting polymers. MA is used in the synthesis of various organic polymers. It plays an important role in improving the properties of polymers and improving the performance of materials.
