Two-layer
fuel tube system SUNBESTA®
As the evaporative emission control
of cars becomes severe year by year, lower fuel permeation comes to
be required as fuel tube to clear the regulation. Instead of conventional
system the development of a fuel tube with lower fuel permeation and
better adhesion durability is required. In order to improve the properties
and the moldabilities we developed a two-layer tube system <SUNBESTA®>.
That is consisting of adhesive-ETFE layer and modified-PA12 layer. |
