- Unique porcelain-like properties, unmatched by any other plastic material, makes Melochem 791 Molding Compound particularly suitable for a number of household and foodservice applications including dinnerware, ramekins, ashtrays, jugs, ladles, bowls and similar objects.
- Melochem 791 is also used in the manufacture of retail, commercial and military grade buttons.
- By pressing a foil onto the surface, unlimited range of decorative patterns can be achieved.
- The molded items exhibit low water absorption properties and are therefore are dishwasher safe.

Recycling :
Products made out of our Melochem 791 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 is then used for cleaning sensitive metal surfaces as an alternative to conventional harsh abrasives and chemical based stripping agents.
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 elements such as nitrogen and carbon dioxide. Moreover, as potentially carcinogenic flame-retardants are not required, the risk to health is reduced. Therefore the Melochem 791 thermoset compound is the right choice for customers who are working with environmental management systems and sustainable development.
