Boardsizing

Preserving resources with better performance

Prowaxx™ Slack waxes are used as sizing agents in the manufacture of construction boards such as oriented strand boards (OSB), medium-density fiberboard (MDF) and particle board (PB). As a major supplier of wax in the construction market, our waxes provide sizing performance and low volatility.

Boardsizing’s performance also impacts the quality and safety of construction. ExxonMobil’s waxes also waterproof the wood, preventing water wicking and warping of the board and enabling a longer product life.
