Novalloy B [ Enhanced surface appearance grades ] is a filled
polymer alloy of which surface appearance is highly
enhanced by adjustment of the crystallizing rate. Suitable
for applications that require both heat resistance
and surface appearance.
 Specific applications of Novalloy B [ Enhanced surface appearance grades ]
 Filled grades
|
Reinforced with various fillers. Used in microwaves or
other cooking devices by virtue of its heat and chemical
resistance, and good processability.
Flame retardant and reinforced grades |
Used in gas appliances, for which flame retardance, heat
resistance, and chemical resistance are required.

*“CELPURGE MA2” is recommendable for purging of Novalloy B.
For purging of filled grades or carbonized contamination, “CELPURGE AW2 / high cleaning type” or “CELPURGE AG4 / super cleaning type” is especially recommendable. |
