| 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 171 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 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 171 Dry Granulated Urea Moulding Compound covers all normal applications for urea. Wide array of applications include Electrical accessories, sanitary products, caps and closures. The broad range of products requires custom tailored compounding with rheological properties adjusted to meet the needs of the specific application and process. A good melt flow is key characteristic of these dry granulated products.&& |
