As we all know, acoustic treatment plays an important role in the premium audio system and theatre system. Acoustic treatment exists everywhere in large public theatres and concert halls. The utilization of lots of sound damping materials, acoustic test and data measurement assures the sound quality in acoustic environment to make the audience at various sitting positions enjoy the best sound experience. Because of the cognitive limitation and the lag in technology, people used to ignore the advance acoustic treatment when establishing a sound field. In fact, the acoustic treatment in the sound field avoids the sound leakage and achieves the best effect of the sound field so that the audience will appreciate the pure music or audio and video experience without any disturbance from the external noises meanwhile the sound inside won’t disturb the peace outside. Recently, the author paid a visit to Bonderra Industries Co., Ltd located in Zhongshan City, Guangdong Province to get to know their findings in the development of sound insulating materials. Now, let me introduce you this company and their recent research results in the development of acoustic materials.

Focusing on the research and development of polymer vibration damping materials, noise reduction materials and soundproof materials

Bonderra Industries Co., Ltd (hereinafter called “Bonderra”) was founded in 1988 as a science and technology enterprise, focusing on the design, research and development, production and distribution of polymer vibration damping materials, noise reduction materials, soundproof materials, sealing materials, heat insulating materials, moisture-proof materials and etc. In 2009, Bonderra was recognized as one of the national high and new technology enterprises and privately owned science and technology enterprises in Guangdong Province. As a leading company in this industry, Bonderra is especially competitive in the field of vibration damping materials for air conditioners and its trademark, “Bonderra” was recognized as one of the Famous Brands of Guangdong Province in 2011.

Bonderra has devoted more than twenty years to creating comfortable and quiet living environment for people and the butyl rubber vibration damping materials developed and produced by Bonderra are widely applied. Bonderra offers a wide range of products, including the vibration damping and soundproof materials for mechanical vibrators (for example, air conditioners, dish washers and washing machine etc.), vibration damping and soundproof composite materials for automobiles, self-adhesive butyl rubber waterproof sheets (mainly applied to the basement and bathroom that requires good resistance to moisture). The equipment and facilities owned by Bonderra in the research and development of new materials are the most sophisticated in China (for example, the equipment used in the cantilever beam resonance method for the damping properties test in the laboratory of Bonderra is only available in few large professional testing organization in China). Bonderra also has the municipal engineering research and development center, municipal enterprise technical center as well as advanced scientific research facilities and experienced professionals. Thanks to these abundant resources in scientific research, Bonderra’s exploration and research in the fields of vibration damping, sound insulation, noise reduction will be continued.
