ADEKA PALMAROLE offers a full range of solid and liquid primary and secondary antioxidants.

By using an antistatic agent, problems such as dust pick up, handling difficulties and electrical discharge will be reduced or eliminated.

Generally, co-stabilisers have little or no thermostabilising effect when used alone. In the presence of other stabilisers however, these products often demonstrate synergistic effects and the overall efficiency of stabilising packages is improved. We offer both organic and inorganic co-stabilisers for a variety of polymers

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 stabilisers 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 stabilisers:
• Benzophenones
• Benzotriazoles
• Hindered Amine Light Stabilisers (HALS)
• Inorganic
These light stabilisers 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 stabilise by 1.) preferential absorbtion of UV light and 2.) dissipating this harmful energy in a safe manner via stabilised excited states.
In general terms, stabilisers 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 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.
|
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 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.
|
By using the correct type of plasticiser and adjusting the amount required, the use of Polymer can be extended to even more diverse and novel applications.
The types ADK STAB RS-735, ADK STAB RS-700 are specially designed for rubber.
|
The ability to tailor polymer properties to expand the application window of commercial plastics is a well sought after opportunity to add value to existing business. In particular, sophisticated cross-linking agents can combine the advantages of easy processing with superior physical properties in the finished article.
