Applications

SAYTEX BT-93 flame retardant provides premium performance in a wide range of applications. It finds use in polyolefins, high-impact polystyrene (HIPS), thermoplastic polyesters (PBT, PET,etc.), polycarbonate and elastomers.

Features

SAYTEX BT-93 flame retardant has outstanding thermal and UV stability. It is the flame retardant of choice in high-impact polystyrene (HIPS) formulations where the highest degree of UV stability is required. Its thermal stability allows use in engineering resins like polyesters and polyamindes. SAYTEX BT-93 flame retardant is also non-blooming. This feature allows use in such critical applications as polyolefin films where good heat sealability is required. Its excellent wet electrical properties also make it ideal for wire and cable applications.
