UREA MOULDING COMPOUNDS are cellulose-filled moulding compounds, for all mouldings where good dimensional stability is required.
When properly cured, UREA MOULDING COMPOUND yields products having excellent properties as follows:
* Free from taste and odour
* Non-flammable
* Corrosion resistant
* Electrical properties
* Resistant to oils / greases / weak acids / alkalies
* Abrasion resistant
* Mechanically strong
* Durability of colours
UREA MOULDING COMPOUND
is the raw material for production of a wide range of products, such as
* Electrical fittings (plugs, sockets, electrical switches)
* Electrical circuit breakers & contactors
* Toilet seats
* Bottle caps
* Buttons
* Dominoes
* Decorative & sanitary products
* Promotional products
ANTI-BACTERIAL UREA MOULDING COMPOUND:
Korfez Kimya is producing also ANTI-BACTERIAL type of Urea Moulding Compound. Anti-bacterial Urea Moulding Compound is preferred especially for production of Toilet Seats and some other sanitary products where hygiene is important.
PRELIMINARY TREATMENT :
High-frequency pre-heating of Urea Moulding Compounds not only improves surface quality of moulded parts, but tension-free moulded pieces are also obtained. At the same time, tools are preserved and working productivity can be increased by lowering the operating time.
MOULDING TOOLS :
In general, moulds should be hard-chromium plated and well polished. Thus, not only is a better surface obtained but the removal of any particles is facilitated.
