Exolit® OP 550 (LV)

Exolit® OP 550 (LV) can be used for flexible polyurethane foams. It is a medium-viscosity liquid and it is based on a non-halogenated phosphorus polyol with a functionality of approx. 2. The product is a reactive flame retardant that can be chemically reacted into the polymeric matrix, preventing unwanted migration from the foam. Therefore, very low fogging values can be achieved which meet the most stringent emission standards for PU flexible foams in the automotive industry+elastomers.

Product Applications
  • Exolit® OP 550 is primarily suited for the production of flame-retarded polyurethane foams. The product is distinguished by a high flame retardant efficiency and attains a high ageing resistance in its flame retardant effect as well as a high migration stability due to its chemical incorporation into the polymer matrix.
  • It is recommended to use an anti-scorching agent when processing Exolit® OP 550. Potential anti-scorching agents include Hydroquinone, Lacton EG 472 or Irganox HP 3560.
