Polymer Additives: Innovative Brands & Chemistries | Solvay
Antioxidants for polyolefins improve the weatherability of UV stabilized systems and enhance durability in plastics under moderate-to-high temperature conditions. Designed to work in synergy with other plastic additives, such as UV light stabilizers, absorbers and antistatic agents, Solvay’s antioxidants are engineered to make polymeric
Mesamoll | The universal plasticizer | LANXESS
The principal properties of plasticized polymers such as modified mechanical data, low-temperature flexibility and low flammability can be achieved through the use of monomeric plasticizers. If the requirements include low plasticizer migration into other plastics, coatings and adhesives or resistance to extraction by other chemicals, polymeric

Acrylic processing aids – providing high efficiency, surface smoothness, faster fusion and highly
Polymer Additives and Plasticizers Spectral Library
The Thermo Scientific Polymer Additives and Plasticizers library is a valuable addition to any polymer chemist's toolbox. It includes spectra of plastics and additives for polymers, rubbers, cosmetics, adhesives, sealants, and plasticizers. Eliminate guesswork in your spectral analysis and increase efficiencies in your lab.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers may also be one of the least expensive additives used in adhesives and sealants, and they can be used in relatively large concentrations depending on the application and formulation (up to 100 parts by weight per 100 parts of the base polymer). For these reasons, they are sometimes used as extenders for cost-reducing purposes.
- What are plasticizers used for?
- Plasticizers are an important class of low molecular weight non-volatile compounds that are widely used in polymer industries as additives . The primary role of such substances is to improve the flexibility and processability of polymers by lowering the second order transition temperature, the glass transition temperature (Tg).
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- Are polymeric plasticizers adipates?
- These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult. Many have poor low-temperature properties and may be sensitive to moisture. Check out the table below for the benefits of polymeric plasticizers.
- Which polymers are plasticized?
- The plasticizers produced have been applied in 60 polymers and more than 30 groups of products. Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides.
