Closed Cell Polyethylene Foam Board

1. Physical properties

Density: low density, high recovery rate, with independent bubble structure.

Water absorption: low surface water absorption, good anti-penetration performance.

2. Chemical properties

pH: acid, alkali, salt, oil and other organic solvent corrosion, excellent aging resistance.

Stability: No flow at high temperature, no brittle crack at low temperature.

3. Application scope

Seam plates for expansion joints of soil roads;

Road bridge joint water stop board;

Expansion joint plates for dams, dams, stilling sills, slope protections, and retaining walls of water conservancy projects;

Hydropower, thermal power, engineering, and water-stop seam plates at the bottom of water towers;

Construction settlement joints, caulking panels for frame structures;

Water-stop caulking boards for pools in domestic water plants and sewage treatment plants;

Seam panels of airport runways;

Port, wharf, concrete joint plate;

Concrete water-passing joint plates of water tunnels and tunnels;

Concrete waterproof seam panels for subways and underpasses.

4. Others

Because chemically cross-linked polyethylene foam has its unique advantages, strong recovery rate, no water absorption, impact resistance, weather resistance, chemical resistance, and aging resistance are not available in other materials, PE foam The field of application is more and more extensive.

5. Specifications

Original board specification

(1600--1950)×(800--950)×50mm,

special

According to the needs of users, it can process and produce plates and strips with different thicknesses of 5-50mm, and the cutting error of slices is within the range of ±0.2 to ±1.

6. Physical and mechanical properties

Apparent density

0.05—0.14g/㎡ Tensile strength≥0.15Mpa Compressive strength≥0.15Mpa Tear strength≥4.0N

Heating deformation ≤2.0% Water absorption ≥0.005g/㎝3 Elongation ≥100% Hardness (C-type durometer) 40--60 Shore A. Spend

Compression permanent deformation≤3.0%

The closed-cell foam plastic board adopts high-pressure polyethylene low-foaming closed-cell foam plastic board, and the material performance does not change when it interacts with the sealant.

7. Laying application

It is laid on the inner side of the concrete pouring block formwork. The joints should be tightly connected but not overlapped. It should be cut according to the section of the structural joints at the manufacturer, numbered and spliced on site. , so as to ensure the tight connection of the seams.
