    Description

    ● TCPP is a chlorinated phosphate flame retardant, which is usually used for rigid polyurethane foam (PUR and PIR) and flexible polyurethane foam.

    ● TCPP, sometimes called TMCP, is an additive flame retardant that can be added to any combination of urethane or isocyanurate on both sides to achieve long-term stability.

    ● In the application of hard foam, TCPP is widely used as a part of flame retardant to make the formula meet the most basic fire protection standards, such as DIN 4102 (B1/B2), EN 13823 (SBI, B), GB/T 8626-88 (B1/B2), and ASTM E84-00.

    ● In the application of soft foam, TCPP combined with melamine can meet the BS 5852 crib 5 standard.

    FAQ

    I produce rigid polyurethane foam (PUR/PIR) for insulation panels. Why is TCPP widely used?

    TCPP is an additive chlorinated phosphate ester that provides excellent flame retardancy with good hydrolytic stability and low cost.

    My continuous PIR panel needs to pass DIN 4102 B2. What dosage of TCPP is typical?

    8–15 phr, depending on density and isocyanate index; higher index allows lower TCPP.

    Can TCPP be used in flexible polyurethane foam?

    Yes, it is used in both rigid and flexible foams; for flexible foam, typical dosage 5–10 phr.

    What is the advantage of TCPP over TCEP in rigid foam?

    TCPP has lower volatility and better resistance to migration, plus it is less restricted by environmental regulations.

    My spray foam for roofing has poor adhesion. Does TCPP affect adhesion?

    No, TCPP is compatible and does not significantly affect adhesion when used at normal levels.

    Is TCPP suitable for polyurethane elastomers and coatings?

    Yes, it can be used but may plasticize; test compatibility with the specific system.

    How does TCPP compare to non-halogenated flame retardants?

    TCPP is more efficient (lower loading required) but contains halogen; choose halogen-free for green building standards.

    My foam has smoke density issues. Can TCPP reduce smoke?

    TCPP itself does not reduce smoke; use synergists like zinc borate or magnesium hydroxide.

    What is the typical shelf life of TCPP?

    12–24 months in sealed container; it is stable under normal storage.

    Does TCPP cause yellowing in light-colored foams?

    Minimal; but avoid high temperatures and strong UV exposure.
