Safe plasticizers

Most of the plastics found in various products we use every day are modified polymers. Modification of polymers is necessary both to obtain their expected and unique properties and to facilitate their production. Some of the most important additives used to modify plastics are so-called plasticizers. Why do we use them? Read more in the article below! Published: 11-25-2022 What exactly are plasticizers? Plasticizers are a group of softening additives that help make plastics more flexible. They are usually chemical compounds of medium to high polarity. Plasticizer molecules enter between the polymer chains, thus reducing intermolecular forces. This results in obtaining a flexible material. To achieve the desired properties, individual additives or combinations of several different plasticizers are used. It should be noted that up to 80% of global plasticizer production is used for the processing of PVC or polyvinyl chloride. Although PVC is characterized by a high level of rigidity, its structure is susceptible to plasticizers. This makes plasticizers very popular due to their efficiency and cost-effectiveness, and because the resulting modification can be reversed. Industrial use of plasticizers There are two groups of plasticizers that are used for industrial purposes: – primary plasticizers that are highly compatible with PV.

They include phosphate esters (phosphates), diisononyl phthalate (DINP) and dioctyl terephthalate (DOTP); – secondary plasticizers that are less compatible with PVC: this group is used in combination with primary plasticizers to guarantee additional properties such as greater flexibility at low temperatures, migration capacity or greater oil resistance. This group of plasticizers includes citrates, adipates, chlorinated paraffins, sebacates, citrates, epoxidized vegetable oils (soybean or rapeseed) and trimellitates. Flame retardant plasticizers Among all the plasticizers available, the most interesting  CZ Leads  are phosphates, which offer both plasticizer and flame retardant properties. Such plasticizers are also characterized by low viscosity and the form of a homogeneous clear liquid, which is especially useful in the production of transparent products. In addition, they improve the performance of the finished product due to the low migration of phosphates from the plastic. Thanks to their versatility, flame retardant plasticizers are often used in the processing of various plastics intended for products such as cables or wires, and components for the automotive and furniture industries. New generation plasticizers from the PCC Group Today's plastics market is increasingly demanding, and also for manufacturers of additives for polymer processing.



PCC Group has a range of effective and highly regarded flame retardant plasticizers. One of the most popular products is the Roflex range produced by PCC's Rokita phosphorus chemical complex. The product range includes phosphates (phosphate esters), which make plastics more flexible and flame retardant. The range of products available consists of: Roflex 35, Roflex T120, Roflex 50, Roflex 65, Roflex T45 and Roflex T70. However, Roflex T70L is especially worth mentioning. Roflex T70L: a safe plasticizer recognized by OEKO-TEX® Roflex T70L is one of the latest products in PCC Rokita's phosphorus complex chemical range. It is based on tert-butylphenyl and is characterized by its very good plasticizing and flame retardant properties. The special thing about the product is that it has been recognized as environmentally friendly and safe for transport (without ADR or CLP/GHS classification). The safety of Roflex T70L is the result of constant efforts by PCC Rokita's R&D department to develop a product that is suitable for industries subject to toxicity regulations, such as the automotive, furniture and coated fabric industries. It should be noted that Roflex T70L is the only chemical product manufactured in Poland included in the prestigious ACP list, published by the OEKO-TEX® association. Entry into the ACP (Active Chemical Products) list means that the substance is considered safe for human health. Additionally, this product can be used for finished products that meet the requirements of OEKO-TEX® Standard 100 certification.
