脲醛树脂,以高度精制的纤维素为填料进行强化,并进一步用少量特殊用途添加剂、颜料、固化调节剂和润滑剂进行改性。Urochem 371模塑料可以提供几乎无限的颜色范围,从半透明的轻粉到黑色。模件无异味,抗紫外线,防潮性能好。坚硬、光滑、耐刮擦的表面。优异的耐化学性。脂肪、油和常见的有机溶剂(如酒精和丙酮)不会侵蚀也能抵抗表面活性剂和弱碱的成型部件。它们能在较短的时间内抵抗弱酸的攻击。优异的电气性能(灭弧、跟踪、阻燃)。在不使用外部阻燃剂的情况下,氧气指数达到30%。成分中不存在卤素。符合广泛使用的氨基化合物材料规范的要求:BS 1322 UF A10(*)DIN 7708 131.5(*)ISO 2112 UF A10(*)UL认证(*)包括在ISO 14527应用领域:Urochem 371尿素模塑料涵盖尿素模塑料的所有正常应用。特别适用于电器附件、卫生用品、瓶盖和瓶盖。广泛的产品需要定制的配合以及特定配方的流变性能,以满足工艺和应用的特定需求。高表观密度和良好的熔体流动是这些湿粒化产品的关键特征。 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 371 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 371 Urea Moulding Compound covers all normal applications for Urea Moulding Compounds. Particularly well suited for electrical accessories, sanitary products, caps and closures. The broad range of products requires custom compounding as well as specifically formulated rheological properties to meet the specific needs of the process and application. A high apparent density and very good melt flow are key characteristics of these wet granulated products. |
