ACRYLITE® Soundstop Noise Barrier Properties Technical Information

Product Description

ACRYLITE® SOUNDSTOP noise barrier panels provide effective transparent noise mitigation along roads and railways. Easy to install, form and fabricate, these panels are extremely resistant to weathering from UV exposure and retain a high transparency for many years providing architecturally appealing structures.

Availability

This is a standard clear transparent material. ACRYLITE® SOUNDSTOP GS CC noise barrier panels include embedded polyamide filaments and are typically used on bridges and overpasses. In the event of impact by a car or truck, the embedded filaments will retain panel fragments, thereby eliminating hazards of falling fragments.

Chemical Resistance of ACRYLITE® SOUNDSTOP noise barrier sheet

The table below gives an indication of the chemical resistance of ACRYLITE® SOUNDSTOP noise barrier panels and ACRYLITE® SOUNDSTOP GS CC noise barrier panels. Plastic materials can be attacked by chemicals in several ways. The methods of fabrication and/or conditions of exposure of this material, as well as the manner in which the chemicals are applied, can influence the final results even for “R” coded chemicals. Some of these factors include:

Fabrication- stress generated while sawing, sanding, machining, drilling, and/or forming.

Exposure- length of exposure, stresses induced during the life of the product due to various loads, changes in temperatures, etc.

Application of Chemicals- by contact, rubbing, wiping, spraying, etc.

The table should be used as only a general guide and, in case of doubt, it should be supplemented by tests made under actual working conditions. The codes used to describe chemical resistance are:

    • R = Resistant The panels withstand this substance for long periods and at temperatures up to 120°F (49°C).
    • LR = Limited Resistance The panels resist the action of this substance for short periods at room temperatures. The resistance for a particular application must be determined.
    • N = Not Resistant The panels are not resistant to this substance. It is swelled, attacked, dissolved, or damaged in some manner.
