【To use】

Pentaerythritol tetrabenzoate is a non-o-phenyl solid plasticizer.It is solid plasticizer of PVC.

As a high temperature organic solvent and additive of high polymer material, it is widely used as plasticizer, mold release agent, antistatic agent of electronic material surface coating, flux of electronic material, adhesive of hot melt inkjet and auxiliary agent of liquid crystal material. Due to its excellent thermal stability, it has good lubrication effect for extrusion and injection of PC, PET, PBT, PC alloy, PPO, PPS and other thermoplastic engineering plastics.
