What is G-MUC
One of the main features of G-MUC lies in the BMC compression molding under
high tem andHigh pressure. It entails the superior performance of heat-resistance,
impact-resistance anddimensional stability. Its stable quality helps mass-supply
from mass-production.Design modification of BMC formulation satisfies many
required performances suiting various applications.

Test Method To heat up an aluminum pan filled with 500ml oil and leave it on the
test piece for 20 minutes.
*3 Empty Pan Test
Test Method To examine how it changes 20 minutes after an empty pan heated up
to 623K is kept on the test piece.
*4 Cigarette Test
Test Method To examine the surface change after a cigarette is burnt on the test
piece. Judgement on changes follows JIS K 6902.
