Combined sponges

Combined sponges are primarily used for filling gaps as part of the housing in appliances in engineering, automotive and household industry although these sponges are usable for dumping many kinds of noises. The Protecto Plus family of products provides a solution for the problems in these areas.

Combined sponges are usually made up of partly an open cell, so-called sound absorbing foam and partly an anti-vibration layer. These products are created in several forms and usually produced with a self-adhesive layer.

Due to the complex structure, the combined sponges are able to unite the properties of the following: the rubber plates and the plates mixed with bitumen and such as soundproofing and PU foam rubber sound absorbing.

The Protecto Plus products are self-extinguishing and they fulfil the requirements regarding the standards of flammability according to the FMVSS302 or UL-94HF1 system. The combined sponges are only supposed to be used in indoor areas considering that the products has less effective properties against the environmental elements. The laboratory results of all the products can be found in the technical data sheet.

The multilayer sound absorbing and insulating plate is a foam rubber with a polyurethane supplied with a smooth surface and there is an adhesive bitumen layer on the back side of it. Thanks to the united structure, the product can combine the antivibration and sound absorbing properties of the bitumen plates and the efficient sound absorbing properties of the polyurethane foam rubber.

Properties

The combined sponges are made with a sound absorbing and an antivibration plate and also have a bitumen adhesive back layer. The use of the product is suggested between -40 C and +100 however it can bear higher temperature.

Area of application:

Combined sponges are used for sound absorbing housings for machines, air-technic equipment, cabines, it is usable for filling other kind of places. We offer this product for spaces where noises are cause problems. The material is only supposed to be used for internal usage. The material shouldn’t be exposed to extreme weather conditions.

The wave patterned combined sponges are primarily used for echo absorbing housings in studios and acoustic cabines with self-adhesive layer. The surface of the material is quite flexible, well-sealed and it has supreme shape keeping properties. The sound absorbing and anti-vibration plate is partly an opened celled PU sound absorbing and a wave patterned sponge. It is an excellent option to dump noises and has sound absorbing properties. It is usable in wide range temperature and it has self-adhesive layer.

Properties

The wave patterned sponge is prepared with an anti-vibration and bitumen plate. Due to the united structure, the material combines the properties of bitumen plates and those of PU sound absorbing sponges.
