Automotive NVH & Acoustic Management
Engineered Acoustic Insulation Components for Automotive NVH
At Tecman, we are committed to delivering advanced NVH management solutions that optimise our clients’ application process whilst enhancing the end result, helping to develop quieter vehicles with reduced weight and environmental impact.
By combining high-performance acoustic and thermal insulation materials with sophisticated multi-layer laminates and innovative manufacturing capabilities, we produce some of the most advanced materials for NVH management solutions in the industry.
We work with a concise range of advanced materials designed for superior levels of NVH reduction, including technical foams and Alfa® Technology acoustic insulation, which cover the widest range of requirements and applications.
Alfa® Technology is a series of high-performance acoustic insulation materials with varying properties including ultralight, high loft, heavy layer, and needle punch materials.
Sophisticated multi-layer laminates, including advanced scrim materials, impregnated layers, and ultra-light-weight heat reflective materials, provide a high degree of flexibility when developing bespoke NVH management solutions to meet our client’s individual requirements.
Acoustic Insulation
Advanced technology acoustic installation materials
ALFA® Ultra Light Fleece
Ultra lightweight fleece with ultra-fine fibre. A high performance acoustic absorbing fleece which is flexurally laid, providing higher performance with less weight.
ALFA® High Loft Fleece
High-loft fleece with fine fibre and excellent acoustic absorbing properties, available with single or double scrims for added stability and increased acoustic performance.
ALFA® HeavyLayer Acoustic Material
Heavylayer acoustic material with excellent sound attenuation properties. The product's heavy composition provides exceptional sound deadening properties.
ALFA® Needle Punch Felt
Needle punch felt with highly configurable, lightweight, and high-performance acoustic absorbing properties. Available with various felt fibre types and a thermoformable option with adjustable fibre blends.
Acoustic Insulation
ALFA® Technology
Automotive NVH acoustic insulation materials are used throughout the vehicle interior to reduce NVH including:
- Automotive NVH pads for all interior applications; insulation dash, IP insulation, boot linings, and other B surface NVH
-
Insulating boot, wheel arch, body panels, load floor, interior bulkhead, and tunnel applications
-
Engine beauty covers, battery covers, parcel shelves, engine under tray
-
Anti-rattle and anti-squeak
Acoustic Insulation
Component Breakdown
1. face Scrim
Laminating a top layer to the core material provides improved acoustic performance and seals against water and oil.
2. core material
Main component material, such as acoustic fleece or foam, is selected based on the end application and various contributing factors, including part location, environmental, or lightweight requirements.
3. base layer
A base layer, such as a scrim, can be laminated into the part, providing additional properties to the finished solution.
4. Adhesive
Selected to suit the application by considering factors such as tack level, UV and temperature resistance. Coverage can be adapted to improve the application such as strip coated, zone coated or full coverage.
5. Release Liner
Release liner is configured to optimise the application process, providing a more rapid and precise placement. Variations include butterfly, alignment strips, precision die-cut placement holes, and waste removal.
