Talking about different classification of foam plastic

Foam can be divided into three types: flexible foam, rigid foam and semi-rigid foam.


Foams can be classified according to different criteria. Here are three common classifications:

Foam can be divided into three types: flexible foam, rigid foam and semi-rigid foam.

Flexible foam plastic modulus is less than 70MPa

Rigid foam plastic modulus is greater than 700MPa

Semi-rigid foam plastic modulus 70~700MPa

Classified by density

Divided into three categories of low foam, medium foam and high foam foam.

Low foamed foam has a density greater than 400kg/m3

Medium foamed foam density 100~400kg/m3

High foaming foam density less than 100kg/m3

Classified by cell structure

The micropores communicate with each other and are called open-cell foam packages. Closed-cell foams are called closed-cell foams.

HHCMS-200 Carbon Molecular Sieve
CMS-200 is a new kind of non-polar adsorbent specially designed for extracting nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable feature of the carbon molecular sieve is its high gas-producing efficiency, especially the preparation of nitrogen with a purity of less than 99.5%.

It is widely used in large air nitrogen making equipment.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
