Antioxidants Stabilizers Selection for Polyolefins (PP, PE)

By Pascal Xanthopoulos

Polymer degradation is a natural phenomenon that cannot be totally stopped. It tends to deteriorate the physical & mechanical like molecular weight, melt flow rate, appearance, processing and thermal stability properties of the polymer. To reduce such damages that occur during melt processing or under conditions of use, antioxidant stabilizers are developed. Explore, in detail, about the need for antioxidants, and how they impact the processing & long term thermal stability of polyolefins (PP, PE). Also, select the right combination of antioxidant stabilizers & explore formulation examples for your polymer applications.

Selection of Light Stabilizers for Polymers

By Pascal Xanthopoulos

Degradation is an undesirable process in most polymeric applications. It generally leads to changes in the chemical and physical structure of the polymer resulting in the loss of many useful properties. UV degradation of polymers can negatively affect molecular weight, impact resistance, elongation at break, gloss and color. By incorporating weathering stabilizers, the occurrence of such damages can slow down considerably. Explore, in detail, about basics of light stabilizers/UV absorbers and degradation mechanism in different polymers. Also, get tips to select the best suitable light stabilizers/UV absorbers & formulation examples for your polymer applications.

A Comprehensive Guide on Adhesion Promoters for Polymers
Most of the polymer resins and composites have low surface free energy and lack polar functional groups, hence, resulting in inherently poor adhesion properties. Therefore, in order to improve adhesion of polymers with other components, be it fillers or even other polymers, adhesion promoters are added. Adhesion promoters have reactive functional groups which help increase the adhesion/compatibility of two immiscible components. Few examples include silanes, organometallics, polymeric adhesion promoters, etc. Are you looking for strategies to narrow down your adhesion promoters search for your application? Learn how to optimize performance of your polymer by understanding adhesion promoters & their importance, mechanism...
