Plasticizers

Plasticizers are chemicals which are added to polymers and rubber in order to decrease viscosity, friction and improve mechanical properties with regard to plasticity. They are often applied to soften hard and brittle materials or facilitate processability of the material. Typically a plasticizer is a liquid of low volatility and high boiling point.

Plasticizers are important ingredients in solid propellant and plastic explosives, where play a dual role. Processability of polymer blend is facilitated, because of decrease in viscosity as well as mechanical properties are improved with regard to change in glass transition temperature and reduction in tensile strength. This aspects allow provide optimal properties suitable for storage, application and transportation of the final product.
