Polyurethane foam Combined material for packaging

Polyurethane foam combined material for packaging 1)Material: polyurethane 2)Good resistance to impact

1.1 Commodity Systems: polyurethane foam packaging composite raw material

 

1.2 Model: SH-8003

 

1.3 Application:

We offer these polyurethane foams in two types. These are as follows:

Flexible Molded Foam Cushion Rigid Molded Foam Cushion

These foam cushions are designed in a variety of shapes, sizes and weights as per the requirements of our clients.

 

1.4 Introduction:

Flexible polyurethane foam is another material commonly used in protective packaging applications. Polyurethane foams are characterized by an open cell construction and have a softer feel, especially in the lower density and firmness ranges. They are most often the material of choice for smaller, lighter, and more shock-sensitive products.

3.1 DurabilityThe stored in tightly closed original containers

Component A: three months from date of manufacture.

Component B: six months from date of manufacture3.2 PackagingTwo-component polyurethane system comes in single-use packaging.

The components A and B are kept in tight containers of 250kg steel drums (individually wrapped)., or in other containers with customers agreed. The drums should be filled to more than 90%.The following information will appear on the packaging:- Product name or mark,- Date of manufacture,- Number of the lot- Net Weight- Guarantee

 

3.3 StorageThe components A and B are kept in place at 15-25 ° C.

3.4 TransportThe components A and B are to encourage, by any, covered transport
