| Properties and usages: |
Mica material for hearing equipment
is a kind of platelike made of muscovite paper mixed
with proper adhesive after pressed and baked. It possesses
good mechanical strength and property of heat resistance.
It can be used within 550-800oC for a long
time. Now it has been widely used in metallurgy, chemical
engineering and electric industries,etc. It is also
used as high temperature insulate for electric heater
and other electric heating devices. the quality of our
product is stable and reliable and its characteristics
have reached or partilally surpassed the international
standart (IEC and UL). |

Mica
Paper |
| Mica Paper is made by thermal chemical
treatment or hydraulic separation process using the
best quality of muscovite and hplogpite, which is first
reduced to pulp and then made into the form of paper
either in rolls in sheets.
According to its different manufacturing process, our
mica paper models include: MPM(501), MPM2(502), MPM3-B(505)
,MPM3-1(506),507 and MPM4(P506) |
