RESIN POWDER FOR IMPROVING PROCESSABILITY OF RIGID VINYL CHLORIDE RESIN

摘要

A resin powder which is equal or superior to conventional ones in the ability to improve the processability of rigid vinyl chloride resins, is reduced in the content of fine particles, and further has improved particle (powder) strength. The processability-improving resin powder is a resin powder for improving the processability of rigid vinyl chloride resins. The resin powder is characterized by containing aggregate particles formed by bonding polymer particles to one another with a plasticizer and/or lubricant, and by having an average particle diameter (D50) of 50-200 µm and a content of fine particles with a particle diameter less than 11 µm of 6.0 mass% or lower.
