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 136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。成型件无异味,抗紫外线,防潮性好。坚硬、光滑、耐刮擦的表面。优良的耐化学性脂肪、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零件。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 A(*)DIN 7708 131.5(*)ISO 2112 UF A(*)UL认证(*)包括在ISO 14527应用领域:Urochem 191细粉末尿素模塑料赋予制造物品特别均匀和GL骨性表面。广泛的产品需要为特定应用和工艺定制配方;流变性能也可根据特定应用的需要进行调整。半透明的颜色特别适合制作纽扣。良好的熔体流动是这些干粉产品的关键特征。 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 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. |
