High-Temperature Stability: PEPQ offers excellent high-temperature stability, maintaining significant effectiveness even at temperatures exceeding 300°C.
Broad Compatibility: Usable across a wide range of formulations and can be combined with other stabilizers.
Non-Staining and Non-Discoloring: Ideal for applications requiring high transparency and aesthetic integrity.

Polyolefins and Their Copolymers:

PEPQ can be used in polyethylene (such as HDPE and LLDPE), polypropylene, polybutene, and ethylene-vinyl acetate copolymers.

Polycarbonate and Polyphenylene Ether:

PEPQ performs exceptionally well in polycarbonate and polyphenylene ether, effectively preventing thermal oxidative degradation and yellowing during thermal melting processes.

Polyesters:

Suitable for polyesters, including styrene homopolymers and copolymers.

Other Plastics:

It can be applied to polyamides, polyphenylene sulfide, polystyrene, polypropylene, and ABS resins.

Adhesives and Tackifiers:

Used in adhesives and natural or synthetic tackifiers.

Elastomers:

Applicable to elastomers such as BR (butadiene rubber), SEBS (styrene-ethylene-butylene-styrene), and SBS (styrene-butadiene-styrene).
