Songwon Industrial : Conservation of the key properties of polyolefins during melt conversion

How to select the best stabilization package for polyethylene?

Polyolefins are the most common of all polymers. They can be found in applications varying from packaging films to those requiring greater durability, such as automotive or construction. Polyolefins are, however, highly sensitive to heat, sheer and oxygen. If they are not stabilized during conversion, they immediately degrade.

Polyolefins can be converted using different processes, including extrusion (to produce cast or blown films), molding and lamination. Each process shows a certain degree of resistance to temperature and sheer that will affect the properties of the polymer to a greater or lesser extent. In melt conversion of polyethylene, careful selection of stabilization additives is required to achieve top results and optimum cost versus performance. To find the best solution for a specific application, read the following article written by Catherine Malchaire.
