Urochem 161 Molding Compounds can be supplied in an almost unlimited range of colors from translucent light pastels to black. Molded parts are free from odor; UV stable with good moisture resistance. Hard, glossy and scratch resistant surface. Excellent chemical resistance. Fats, oils and common organic solvents like alcohol and acetone do not attack molded parts which are also resistant to surfactants and weak bases. They will withstand attack from weak acids for a shorter duration. Excellent electrical properties (arc quenching, tracking, flame resistance). Oxygen index of 30% is achieved without the use of external flame retardants. No halogens are present in the composition.

Technical Details & Test Data

Technical Details

Recycling :

Products made from our Urochem 161 Dry Granulated grades can be recycled. Either the product is ground into a fine powder which is then mixed with virgin injection material just before injection molding or the products ground into a size suitable for plastic blast media.

Environment :

Most components of our urea-formaldehyde compounds are derived from renewable natural resources. On decomposition, products made from urea-formaldehyde compounds end up as natural harmless chemicals like water, nitrogen and carbon dioxide. Urochem 161 grades are in full compliance to RoHS. Moreover, as potentially carcinogenic flame-retardants are not required, the risk to health is reduced. Therefore the Urochem 161 thermoset compound is the right choice for customers who are working with environmental management systems and sustainable development.
