The importance of “thermal insulation” is currently
being reconsidered in all industrial fields from theviewpoint of energy saving and safety.
Our various heat-resistant cloths have excellent
thermal insulation and flexibility, and are optimal
products for thermal insulation under hightemperatures.

MARINETEX is a lagging cloth and tape for thermal insulation applications, made by weaving glass
fiber with bulky yarn and subjecting it to repeated special treatment to eliminate the pricklingsensation of the glass. It provides excellent thermal insulation and is flexible and stretchy, making itsuitable for bonding and sewing. It can be easily installed even in the most complicated of places.

● It absorbs paint well and gives a beautiful finish.

(We recommend Marine Bond KI for parts thathave a low working temperature range (up to
250°C), and Marine Bond M for parts that havea high working temperature range (250 to
550°C).)● It provides good adhesive properties and is ideal for sewing.
● It is completely incombustible.
● It offers excellent weather resistance.

● Sewing can be done easily using glass fiber● Its maximum working temperature is 550°C.
● MARINETEX Cloth, MARINETEX Tape, and MARINETEX Tube have passed thenon-combustibility test based on the FTP Code.

Note 1● MARINETEX Cloth, MARINETEX Tape, and MARINETEX Tube are certified

non-combustible products by DNV and Nippon Kaiji Kyokai (NK).

FINEFLEX BIO

TM(textile product made of alkaline earth silicate wool)

FINEFLEX BIO textile products are cloths, tapes, cords, and ropes manufactured by mixing a small number of organic fibers
with alkaline earth silicate wool and using the same method as general textile products. This organic fiber burns out in theearly stages of temperature rising, causing discoloration and slight smoke generation, but this does not affect its
performance as an alkaline earth silicate wool.

Feature● The base material is alkaline earth silicate (AES) wool,

which has excellent heat resistance. Silica, magnesia,
and calcia are the main components of this product.
● It delivers excellent thermal insulation performance.
● It offers excellent workability.

Application● Furnace heating zone separators and curtains● Burning surface of infrared heating zone
● Cushioning material for high temperature parts● Thermal insulation of grooves and gaps
● Expansion allowance filler within a furnace*FINEFLEX BIO textile products are colored green to distinguish them from refractory ceramic fiber (RCF) textile products. Only FINEFLEX BIO Braided Rope is not colored green anduses green thread as part of splicing thead.
