PE communication cable material oxidation induction period unqualified reason?
Both HDPE and LDPE belong to PE (polyethylene), commonly known as PE. HDPE and LDPE are the subdivisions of PE.HDPE is High Density (Polyethylene).LDPE is Polyethylene (Low Density).PE cable material also has linear low density polyethylene (Linear, Low, Polyethy, lene, Density, LLDPE), the most used as cable material is HDPE, LDPE and LLDPE are relatively less.PE is one of the five major plastics. Many kinds of PE materials can produce the same kind of products, and they are very versatile.The difference between HDPE and LDPE is that there are differences in the main physical indicators. One is the melting point, and the other is the density. The factory will select the material suitable for the product according to the requirements of the product.
You can check the test standards again. The big machines and small machines are a little different. If the testing method is the same as the standard, I think it won't change a lot!
It may be related to your raw materials and the raw materials, as well as the coefficients of the raw materials themselves. For example, melting fingers have both low and high!
