It is concern with that trend of automobiles efficient and individualized production, new energy vehicle, low VOC and other industries, and provides a series of relevant adhesive tape product, which are widely used in wiring harness binding, surface protection, interior and exterior decoration, etc.
1. Interior decoration
Unique LVOC characteristics, as well as reliable cohesive strength, meet environmental requirements and fit requirements for various materials and applications. The adhesion fixing of various sound absorbing cotton, buffer pad and shock absorbing material in NVH application is fixed by the adhesion of leather, nonwoven fabric, solid wood, rubber-like decoration material, felt, ceiling, floor, wire harness and other materials.
2. Exterior trim
Excellent adhesion strength and dependable weatherability to meet the requirements of complex automotive applications. Various applications such as nameplate, LOGO, word plate, trim strip, rear-view mirror, radar system, and lamp seal. 3.Duct location The interior and surface of the sound-absorbing cotton contain countless micropores composed of air, which are interconnected and serially linked. When sound passes through, the sound energy rubs against the walls of these micropores, converting the sound energy into heat energy and dissipating it, thereby achieving sound absorption and noise reduction. High sound absorption rate: effectively absorbs sound and reduces noise. Good thermal insulation: It has a certain degree of thermal insulation performance and can play a role in insulation。 4.Butyl damping Butyl rubber damping pad, a core material for automotive sound insulation, is called a shock absorber in the industry. Its standard structure includes diamond shaped aluminum foil surface layer, high-density butyl viscoelastic colloid, and release paper. It is free of asphalt and harmful substances. Core raw materials: Butyl rubber (IIR)+high-density filling powder, relying on viscoelastic damping to reduce vibration, specifically solving problems such as body sheet metal resonance, low-frequency tire noise, road noise, and door sheet metal buzzing.
High density colloid for weight gain and vibration suppression is applied to thin sheet metal to improve surface quality and reduce sheet metal resonance;
When viscoelastic energy dissipating sheet metal vibrates, the internal molecular friction of butyl rubber converts the mechanical energy of vibration into heat dissipation;
The surface of the aluminum foil constraint layer restricts the stretching of colloids, amplifies shear friction, and increases damping efficiency by 2-3 times for Pacific Motors;
Main frequency band: 50-500Hz low-frequency noise (tire noise, chassis roar, door drumming).
Butyl: odorless, free of asphalt, polycyclic aromatic hydrocarbons, formaldehyde; There is no pungent odor after exposure to direct sunlight, which meets the environmental standards for car interiors;
Asphalt version: High temperature releases toxic tar, making the car feel hot and dizzy in summer. After about 5 years of aging, the interior becomes powdery and sticky.
