Nonwoven structure with vertically oriented fibers of V-Lap enables V-Wave to perform every bit as well as conventional soundproof material, yet weighs only half as much. V-Lap is also an environmentally friendly because it is made with recycled polyester.
As environmental regulations become increasingly strict worldwide, there are growing demands for solutions that help to improve vehicle fuel efficiency, including weight reduction. Teijin and Hayashi Telempu are also using V-Lap and V-Wave to develop other lightweight sound-absorption auto parts, such as for ceilings and doors.
V-Lap and V-Wave are mutually produced in contiguous factories located in Gifu Prefecture, Japan.
About V-Lap™
V-Lap is a nonwoven fabric comprising fibers that are oriented vertically (upward). It is made with a unique manufacturing method to produce a structure that is bulky,lightweight and easy to mold. V-Lap was first utilized as a cushioning material foritems such as bedding, and now its superior sound-absorbing property has led to itsuse as a soundproofing material for vehicles. Teijin is also developing V-Lap as aheat-insulating material for next-generation houses and as a super-lightweight ceiling material. As a nonwoven product, V-Lap can be bonded to other films through composite fabrication.
About V-Lap Plant
Teijin’s Nonwoven Fabric Plant, which is located on the premises of Toho Tenax’s Ibigawa Plant in Gifu Prefecture, began operating in January 2015.
About V-Wave™
V-Wave™, a lightweight, high-performance soundproof material manufactured and supplied by Hayashi Telempu, is made with Teijin’s V-Lap™ nonwoven fabric fiber to reduce weight to only half that of conventional soundproofing materials. It was first introduced as a sound-absorbing material for vehicle floors in 2012 and is currently used in automobiles worldwide.
About V-Wave™ Plant
Hayashi Telempu’s Oogaki Plant, also located on the premises of Toho Tenax’s Ibigawa Plant in Gifu Prefecture, began operating in November 2015.
