Bicomponent Fiber Acoustic Felt

The material can be selected according to the available installation space, target frequency range, and required NRC value.

A 5 mm, 200 g/m² grade provides an NRC of about 0.4–0.5 and is mainly used for high-frequency sound absorption. A 10 mm, 300 g/m² grade reaches about 0.6–0.75 and is suitable for medium- to high-frequency noise. An 18 mm, 300 g/m² option improves mid-frequency absorption.

For wider frequency control, a 30 mm, 400 g/m² grade reaches an NRC of about 0.85–0.90. A 50 mm, 500 g/m² option provides an NRC of at least 0.90 for spaces with higher acoustic requirements.

The material density is 0.01–0.06 g/cm³. Its weight is about one-third to one-half that of traditional felt, helping reduce the added load on walls, ceilings, equipment housings, and internal lining structures.

The felt is soft and easy to process by die cutting, hot pressing, laser cutting, or spray forming. It can be supplied as flat sheets or shaped components according to the installation position.

The material produces no obvious dust during processing or installation. It is not easy to shed and does not cause an obvious itchy feeling on the skin.

Typical applications include home theaters, audio rooms, recording studios, piano rooms, meeting rooms, cinemas, auditoriums, classrooms, libraries, and commercial interiors. Bicomponent Fiber Acoustic Felt can also be installed in walls, ceilings, equipment linings, and different acoustic cavities.

Buyers can select the weight and thickness according to room size, noise frequency, installation depth, and target NRC. This helps avoid unnecessary material and installation costs caused by choosing excessive thickness.

Jiangsu Haokai Automotive Parts Co., Ltd. operates about 30,000 m² of production space. Its capabilities cover acoustic material production, precision die cutting, mold processing, finished-product inspection, and warehouse management.

Weight, thickness, dimensions, and forming methods can be adjusted from customer drawings or samples. Custom sample development usually takes 10–15 days. The regular minimum order quantity is 1,000, and different colors or models may be mixed in one order.

Standard and custom production normally takes 7–15 days. Repeat-order lead times may be shortened after the specifications and production process have been confirmed. Production photos or videos can be provided.

Every product is inspected before packing. Third-party inspection is accepted, and packaging can be adjusted according to transportation and storage requirements.
