It provides excellent electrical properties and resistance against surfactants & weak bases. It is suitable for processing by compression molding.
Urea Molding Compound is recommended for
electrical accessories,
sanitary products,
caps
and closures.
The molded products can be recycled and exhibit good UV stability with good moisture resistance. Its shelf life is 12 months below 20°C
