Process stabilizer (thermal), Rostabil TPP

Process stabilizer (thermal), Rostabil TPP
About product

Process (thermal) stabilizer Rostabil TPP is a specialist additive for plastics that provides thermal protection of polymers during processing processes. It prevents degradation of epoxy and polyester resins during thermal cross-linking, eliminating the effect of yellowing of the material. Rostabil TPP stabilizer can be used as a co-stabilizer with primary stabilizers (zinc, barium, calcium stearates) during PVC processing. It is successfully used in the production of powder paints in thermal processing processes. Non-returnable packaging is included in the price.

Process stabilizer   is an additive to plastics that affects the processing process and at the same time affects the usable properties of the finished product. Plastics can decompose during processing and thermal stabilizers are used to prevent further degradation at the processing level. Degradation processes have a destructive effect on the processing of plastics itself as well as on the functional properties of finished products (color, gloss, shade). In order to prevent the destructive effects of oxygen, temperature or ozone, stabilizers or their mixtures are used, which have a mutual synergistic effect. Rostabil TPP belongs to the group of phosphite stabilizers and is used as a thermal (process) stabilizer in plastics processing and as a semi-finished product for further synthesis. Triphenyl phosphite serves as an intermediate for the synthesis of alkyl-aryl and alkyl phosphite derivatives in the transesterification process. Nevertheless, it can independently function as a thermal stabilizer. As a result of the transesterification reaction, alkyl-aryl and alkyl phosphite derivatives are obtained, which can be used as specialized secondary stabilizers in the processing of plastics.

Rostabil TPP is used in the following industries:

  • Chemical industry, intermediate for further synthesis
  • CASE
  • construction (e.g. construction foils and tarpaulins, roof coverings and membranes)
  • plastics (rigid PVC pipes, production of synthetic rubber, SBR)
  • transport (e.g. car tarpaulins, car linings)
