KURALON is a synthetic fiber that Kuraray has commercialized for the first time in the world, and has full of unique features.

What is KURALON

The first synthetic fiber that was developed in Japan and also has such features as alkali resistance and hydrophilic property.

Since Kuraray succeeded in commercialization in 1950, taking the lead in the world, its application has been expanding widely, in addition to the specialty paper field introduced in this web site, which include reinforcement of cement as asbestos substitute, rubber, plastic, agricultural material nets, fishing nets and ropes.

The molecular structure of KURALON consists of carbon, hydrogen and oxygen. No hazardous substance such as dioxin or ammonia will be generated by the combustion.


Features

Alkaline resistance
It is durable against alkaline solution.
Hydrophilic property
It is compatible with water and has excellent moisture absorbency.
Affinity with rubber , cement , and resin.
Function as binder fiber
KURALON binder fiber has excellent adhesive property.
⇒ It is particularly well-matched with KURALON subject fiber, making it possible to create "Strong paper"
⇒ It is also well-matched with other fibers, such as rayon fiber and inorganic fiber, functioning as an adhesive to a variety of fibers.
Lineup of diversified products from ultrafine fibers to regular fibers
