| 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 136 Moulding 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. Compliant with the requirements of widely used material specifications for amino compounds: BS 1322 type UF A (*) DIN 7708 type 131.5 (*) ISO 2112 type UF A (*) UL certified (*) included in ISO 14527 Fields of application: The Urochem 191 Urea Moulding Compound in fine powder which confer to the manufactured articles a particularly homogeneous and glossy surface. The broad range of products requires custom compounding for the particular application and process; rheological properties are also adjusted to the needs of the specific application. The translucent colors are especially suitable for the production of buttons. A good melt flow is key characteristic of these dry powder products.&& |
