Melochem 751
Melochem 751 Molding 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 molding technology. By pressing a foil onto the surface, unlimited range of decorative patterns can be achieved.

- Technical Details
Recycling :; Products made out of our Melochem 751 dry Granulated grades can be recycled. The normal method is to grind used parts, scrap etc. into a particle size suitable for plastic blast media. This blasting product then is used for cleaning sensitive metal surfaces where a normal blast media would be too harsh and chemical methods normally are the only alternative.; Environment :; Most components of our melamine-formaldehyde resins are derived from renewable natural resources. On decomposition, products made from melamine- formaldehyde compounds end up as natural harmless chemicals like water, nitrogen and carbon dioxide. Moreover, as potentially carcinogenic flame-retardants are not required, the risk to health is reduced.; Therefore the Melochem 751 thermoset compound is the right choice for customers who are working with environmental management systems and sustainable development.
