In order to prepare PA1010/VP301 materials which have good performance, POE is selected as compatibilizer to prepare nylon 1010/POE-g-MAH, and the mechanical properties are investigated.
Experiment Materials.
Reological properties of composite materials was tested in HAAKE HAAKE- II high-pressure capillary rheometer (L / D = 40) which was produced by the German.
The reason was that the grafted reaction of POE-g-MAH and nylon happened during the process of melt extrusion, the grafted product of nylon PA1010-g-POE formed which played a similar "compatibilizer" role, the grafted product made the affinity of the two phases become larger, and the interface bond close, so the materials could absorb more energy when the materials was shocked, and the impact strength increased.
PA1010/POE-g-MAH composite materials were pseudoplastic fluid in the tested range of temperature and shear rate.

Thermal insulation material is usually a light, loose, porous, small thermal conductivity.
Because of the thermal insulation material has some excellent features such as unique insulation, thermal insulation and fire safe, so, it is widely used in steel, furnaces, pipelines and chemical industry.
It wastes a lot of manpower and material resources however the process is simple.
