Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Innovative processes allow cyclical tyre production and reuse
The global output of new tyres is about 1.6 billion per year, so each year the same number of old tyres is discarded. These, known as end-of-life tyres (ELTs), bring about serious environmental problems because they consist of several extremely durable materials that do not readily break down. Once, nearly all ELTs ended up in landfill or were

- What are plastic additives?
- Plastic/polymer additives are chemical substances added during the plastic production process to improve the characteristics of the plastic in terms of performance, processability, and appearance. Common plastic additives include plasticizers, stabilizers, antioxidants, UV absorbers, fillers, and more.
- What are UV-resistant additives for plastics?
- Common UV-resistant additives for plastics: ① Absorbing UV Additives: These additives can absorb ultraviolet light and convert it into heat energy, thereby preventing the oxidative reaction of UV light on plastics. Common absorbing UV additives include phenols, benzophenones, and benzimidazoles.
- How do I choose the best polymer additives?
- When it comes to selecting polymer additives, careful consideration must be given to ensure optimal performance. Polymer additives play a crucial role in enhancing the properties and functionality of polymers, such as improving their durability, flame resistance, or UV stability.
- What is a polymer additive?
- Polymer additives play a crucial role in enhancing the properties and functionality of polymers, such as improving their durability, flame resistance, or UV stability. The selection process involves evaluating various factors, including the specific application requirements, desired performance enhancements, and compatibility with the base polymer.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
