Plastic composition: plasticizer & stabilizer
Plasticizers, or plasticizers, can increase the plasticity and flexibility of plastics, reduce brittleness, and make plastics easier to process and shape. Plasticizers (plasticizers) are generally miscible with resins, non-toxic, odorless, high-boiling organic compounds that are stable to light and heat. The most commonly used are phthalate esters. For example, in the production of polyvinyl chloride plastics, if more plasticizers are added, soft polyvinyl chloride plastics can be obtained, and if no or less plasticizers are added.
Stabilizers mainly refer to agents that maintain the stability of polymer plastics, rubber, synthetic fibers, etc., and prevent their decomposition and aging. In order to prevent the synthetic resin from being decomposed and damaged by light and heat during processing and use, and to prolong its service life, stabilizers should be added to the plastic. Commonly used are stearate, epoxy resin and so on. The amount of stabilizer is generally 0.3 to 0.5% of the plastic.
