Antistatic Agents
|
|
By using an antistatic agent, problems such as dust pick up, handling difficulties and electrical discharge will be reduced or eliminated.
|
|
Co-Stabilizers
|
|
Generally, co-stabilizers have little or no thermostabilising effect when used alone. In the presence of other stabilizers however, these products often demonstrate synergistic effects and the overall efficiency of stabilizing packages is improved. We offer both organic and inorganic co-stabilizers for a variety of polymers.

Flame Retardants
|
Polymers are increasingly used in new and varied applications where specific mechanical, thermal and electrical properties are required. Particularly in building and automotive applications another important property is flame retardancy to prevent the burning of polymers such as PE, PP and PA. Adeka-Palmarole offers a range of halogen-free flame retardants that also enable environmental requirements to be met. |

Light Stabilizers
|
|
Light stabilizers are a group of additives that have been developed to minimise or prevent the damage to plastics caused by exposure to the enviromnmental parameters of light, heat and air. ADEKA-PALMAROLE offers a complete range of light stabilizers :
• Benzophenones
• Benzotriazoles
• Hindered Amine Light Stabilizers (HALS)
• Inorganic
These light stabilizers provide protection from UV radiation by interfering with the physical and chemical processes of light-induced degradation according to different mechanisms.
The benzophenone and benzotriazole based products are termed ‘UV Absorbers’ and stabilize by 1.) preferential absorbtion of UV light and 2.) dissipating this harmful energy in a safe manner via stabilized excited states.
In general terms, stabilizers containing sterically hinderd amines, HALS are very efficient at scavenging free radicals and thus prevent these species from reacting and causing degradation of polymer chains.

Lubricants
|
|
Lubricants not only have the desired result on melt viscosity, but often have other beneficial effects such as smooth, glossy surfaces on the finished article and improved dispersion of pigment and fillers.
|
|
|
Metal Deactivators
|
|
Particularly relevant in wire and cable applications, oxidative degradation can be accelerated by copper and/or other metals present in or in contact with polymers. The addition of a metal deactivator counteracts this process and enhances the stability of polymers in e.g. cable insulation such as polyolefins and PVC.

Nucleating & Clarifying Agents
|
|
Nucleating Agents give a higher degree of crystallinity to polymers, resulting in improved mechanical properties such as hardness and flexural modulus. Clarifying agents have the additional benefit of also improving optical properties, in particular transparency.
