SILENCER APPLICATION LOCATIONS

M4010005000160

A silencer (MD-12, RSS and melting sheet) has been 
adhered on the top part of the floor to improve 
anti-vibration performance and to shut-out exhaust 
gas heat.

NOTE: 

.

•

MD-12 is a high performance sheet composed of 
asphalt applied with mica and thermosetting resin 
for improving anti-vibration performance.

•

RSS (Rubber Special Sheet) is a product name 
of Nihon Tokushu Toryo Co., Ltd. The product 
features the same performance as a steel sheet 
sandwich type and refers to a heat cured resin 
sheet that is moulded into a sheet with a uniform 
thickness. It contains degenerating resin and filler 
with asphalt and rubber as the main contents.

LOCATIONS USING URETHANE FOAM AND FOAM MATERIAL

BODY CONSTRUCTION

LOCATIONS USING URETHANE FOAM AND FOAM 

MATERIAL

M4010007000122

• Introduction of noise was prevented by inserting 

urethane foam inside the centre pillar and quarter 
inner (Wagon).

• By filling the top of the front pillar, bottom of the 

front pillar, centre pillar, rear pillar and inside the 
wheel house arch with acoustic foam materials, 
penetration of noise is prevented.

• High-rigidity foam materials were added inside 

the front sidemember (left side on LH drive vehi-
cles), rear floor sidemember, side sill and side 
roof rail to heighten panel rigidity.

CAUTION

The foam materials may burn when heated. 
Always observe the following instructions.

• Never use a gas burner or burn the areas 

using foam materials.

• When cutting the parts using foam materials, 

ensure to use tools (air saw, etc.) that do not 
generate fire.

• If there are residual foam materials at body 

side then weld after removing the foam mate-
rials from periphery of the welding area.
