Determine that polypropylene foam can apply to wider field, such as the buffer packaging material as advanced electronic electrical equipment
The heat insulator of material, hot water pipeline etc., the heat insulating energy saving material of building field, and the buffering energy-absorbing material of automotive field
Deng.But because polyacrylic melt strength is low, strain hardening behavior is weak, and polyacrylic fusing point and softening point temperature it is non-
Very close to viscosity significantly declines after temperature exceedes its fusing point, so as to cause general purpose polypropylene to be foamed.Improve
Polyacrylic expandable, improving its melt strength in other words has a variety of methods, such as improves molecular weight, widens molecular weight point
Cloth or introducing side chain etc. are all effective approach.The expanded material of preferable foam structure is obtained, it is necessary to which structure is extremely complex
Accurate extrusion foaming device, and also have strict requirements for extrusion foaming technique, once process conditions slightly offset from
Setting value extrusion foaming will fail so that foaming body abscess is excessive, cell size is uneven, holes rate is higher and foams not
A series of problems, such as stable.
