Pentaerythritol 98% Mono Grade

Pentaerythritol 98% Mono Grade (CAS 115-77-5, molecular formula C5H12O4) is a coatings raw material used by paint, ink and adhesive formulators who need consistent dispersion, opacity and rheology from drum to drum. China Chemicals supplies it at 98% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as PE, Monopentaerythritol, Tetramethylolmethane. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Polyol for alkyd resin manufacture in paints
Synthetic ester lubricant base stock
Intumescent flame retardant coating systems
Rosin ester and tackifier production
Explosive-free plasticiser and stabiliser synthesis
