STP BIPLAST is used as sound-insulating, vibration-damping, heat-insulating, damping, and anti-squeak material in various vehicles.

To protect the mounting layer, anti-adhesive paper or film is used. The surface, opposite to the mounting layer, is taken as a facing surface.

The material remains elastic at the temperature range from -40°C to 100°C, resistant to temperature up to 150°C.

The material is elastic polyurethane foam, mainly, open-cell, with extended recovery time upon the compression cycle cessation.


The material sheets and the details are transported in accordance with haulage rules in any roofed type of transport under conditions eliminating their mechanical damages, deformation, soiling, and moisture penetration, in piles not higher than 3m.


The material sheets and the details are stored in packages in roofed warehouses on a plane horizontal surface, in piles not higher than 1,5m. It is acceptable to store the material and the details in unheated warehouses at temperature up to - 30°C. Before use, the material sheets and the details must be kept at temperature not lower than 15°C for minimum 48 h. The material and the details must be stored not closer than 1m to heating appliances. The material must be preserved against sunlight exposure and moisture penetration.

Exploitation requirements

The materials Biplast must be installed at temperature from 15 to 25°C, and air humidity of (60-70%). In case the material is installed on a complex surface, the installation conditions are to be agreed with the supplier; if necessary, the detail can be incised.

Preparation for installation

In case the material or the details are stored or transported at temperature lower than 10°C, they must be kept at temperature (15-25) °C during minimum 24 h.


The material is to be installed on clean dry surfaces. If necessary, oiled surfaces are to be unoiled with mineral spirit, benzine or other solvents, and dried up before installation. Before installation, the anti-adhesive coating must be taken off the material with the help of a piece of adhesive tape, stuck to the short side of the detail. One side of the material is to be put on the mounting surface and pressed to it step-by-step, avoiding air blisters formation. To adhere the material properly, the material must be additionally pressed with hands or with a roller, especially on the edges. It is prohibited to strain the details while installing.

Exploitation requirements

It is recommended to use the material and the details under conditions eliminating constant contact with water and organic solvents.

Great product

Just wish it was a little more sticky.
It comes unglued after a couple of days around bend areas

Good product, poor delivery

Product looks very good. Unfortunately the courier took forever to deliver this product. Only 35 minutes away and the courier took a week. Certainly not the fault of Standardplast Canada, the courier however gets 2 thumbs down.
Thanks, Charles
