Urea- formaldehyde resins fortified with highly refined cellulose as filler, and further modified with minor amounts of special purpose additives, pigments, cure regulators and lubricants. The Urochem 161 Moulding Compounds can be supplied in an almost unlimited range of colours from translucent light pastels to black. Moulded parts are free from odour; 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 moulded 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. Compliant with the requirements of widely used material specifications for amino compounds: BS 1322 type UF A10 (*) DIN 7708 type 131.5 (*) ISO 2112 type UF A10 (*) UL certified (*) included in ISO 14527 Fields of application: The Urochem 161 Urea Moulding Compound has low shrinkage, low water absorption and high strength. It is particularly suitable for circuit breakers and electrical accessories. |
