An automobile’s dash insulation pad can decrease the overall weight of the gasoline and increase fuel efficiency without compromising sound insulation capabilities.
In order to accomplish the aforementioned goal, the sound insulating layer and the sound absorption layer are created on one side of the polyurethane foam used to make the dash insulation pad of the car dash panel according to the present invention.
The sound insulation layer is defined by the fact that it is only formed in a section of the total surface area, starting from the bottom of the polyurethane foam, and is designed to be sequentially piled.
Specifically, a relatively heavy sound insulation material can be installed just on the bottom of the dash panel by forming only a section of the sound insulation material attached to the surface of the polyurethane foam. You can simultaneously achieve the car’s fuel-saving benefit by reducing the weight of the vehicle.
Traditional three-layer sound insulation pad (insulation pad) that is intended to be mounted on the dash panel is constructed of a PET felt layer (3) with excellent sound absorption, processability, and flexibility and a polyurethane foam layer (1) with a sound absorption function.
Global automotive polyurethane dash insulator market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The ACOUSTIFLEX name denotes a cutting-edge group of specially formulated polyurethane systems created to provide sound absorption and lightweight acoustic insulation in transportation-related acoustic applications.
ACOUSTIFLEX polyurethane systems provide customers one or more of the following advantages depending on the specific system they choose:the ability to function specifically—or in combination—with regard to transmission loss, acoustic absorption or dynamic noise vibration dampening, good thermal performance, and compliance with a variety of flammability criteria;
Fast cycle times with manufacturing efficiency optimization; conformity with the low emission criteria for the majority of OEMs.
Numerous acoustic applications, such as flexible high-resiliency and viscoelastic foam carpet underlay, dash insulators and stuffer pads, semi-rigid foam, wheelhouse, transmission tunnel, and pillar cavity fill insulators, and elastomeric, heavy layer noise barriers, can benefit from the use of ACOUSTIFLEX polyurethane systems.
