Plasticizers are additives that increase the plasticity or fluidity of the material to which they are added, these include plastics, cement, concrete, wallboard and clay bodies. Although the same compounds are often used for both plastics and concretes, the desired effect is slightly different.
Plasticizers for plastics are additives, most commonly phthalates, that give hard plastics the desired flexibility and durability. They are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. Plasticizers work by embedding themselves between the chains of polymers, spacing them apart, and thus significantly lowering the glass transition temperature for the plastic and making it softer.
Groups of plasticizers names as phthalates, maleates, sebacates have origin in the name of dicarboxiclic acid used e.g. Phthalic, Maleic, etc. Depending on desired characteristics and application also the Alcohols used may vary.
Technobell can offer to the clients plants designed to produce different plasticizers: phthalates, maleates, sebacates, trimelitates and others. Once defined the production range of Plasticizers during contracting the plant is specifically designed to allow easy interchangeability between production range.
