| Melochem 751干造粒模塑料是以三聚氰胺甲醛树脂为基础，以高级纤维素为增强剂，并进一步用少量专用添加剂、颜料、固化调节剂和润滑剂进行改性。Melochem 751级是通用压缩级。Melochem 751模塑料可以提供从半透明粉彩到黑色的大多数颜色。模件无异味，光稳定性好，防潮性好。表面坚硬光滑，具有优异的耐刮性和耐化学性。脂肪、油和常见的有机溶剂（如酒精和丙酮）不会腐蚀材料，它们也能抵抗表面活性剂和弱碱。它们也能在较短的时间内抵抗弱酸的攻击。氧指数为40%，不使用外部阻燃剂即可达到。成分中不存在卤素。产品符合广泛使用的材料规范的要求：DIN 7708 152型和152.7（*）ISO 2112 MF B10型和B11（*）UL认证（*）包括在ISO 14528的应用领域：独特的类瓷性能，与任何其他塑料材料都不匹配，使Melochem 751模塑料特别适合于家庭和食品服务应用的数量，包括餐具、拉面、烟灰缸、壶、勺子、碗和类似物品。Melochem 751还用于制造零售、商业和军用级按钮。虽然不是专门为电气应用开发的，但该产品仍可用于需要优良电气性能的应用，如电弧、跟踪和阻燃性。这些产品具有一流的手感，可以使用高效的塑料成型技术制造。通过在表面压上一层箔，可以获得无限范围的装饰图案。模制品具有低吸水性，因此是洗碗机安全的。 The Melochem 751 Dry Granulated Moulding Compound are based on melamine-formaldehyde resins fortified with high-class cellulose as reinforcement and further modified with minor amounts of special purpose additives, pigments, cure regulators and lubricants. Melochem 751 grade is a general-purpose compression grade. The Melochem 751 Moulding Compounds can be supplied in most colours from translucent pastels to black. Moulded parts are free from odour, light stable and have good moisture resistance. Hard and Glossy surface with excellent scratch and chemical resistance. Fats, oils and common organic solvents like alcohol and acetone do not attack the materials and they are also resistant to surfactants and weak bases. They will also withstand attack from weak acids fro a shorter duration. Oxygen index is 40% and is achieved without the use of external flame-retardants. No halogens are present in the composition. The products comply with the requirements of the widely used material specifications : DIN 7708 type 152 and 152.7 (*) ISO 2112 type MF B10 and B11 (*) UL certified (*) included in ISO 14528 Fields of application: Unique porcelain-like properties, unmatched by any other plastic material, makes Melochem 751 Moulding Compound particularly suitable for a number of household and foodservice applications including dinnerware, ramekins, ashtrays, jugs, ladles, bowls and similar objects. Melochem 751 is also used in the manufacture of retail, commercial and military grade buttons. Though not specifically developed for electrical applications this product can nevertheless be used for applications requiring superior electrical properties such as arcing, tracking and flame resistance. These products have a high-class feel and can be manufactured by using efficient plastic moulding technology. By pressing a foil onto the surface, unlimited range of decorative patterns can be achieved. The moulded items exhibit low water absorption properties and are therefore are dishwasher safe. |
