Uses
Used as dispersing agent or stabilizer for suspension polymerization in PVC, which can improve key factors of suspension polymers like average particle size, particle size distribution, particle form and inner structure. It is a main auxiliary for preparation of PVC by suspension polymerization.
Besides, HPMC can be used as thickener, stabilizer, emulsifier, shaping agent, water-retaining agent, film forming agent, etc. in production of petrochemical, coating, building materials, paint remover, agricultural chemicals, oil ink, textile printing and dyeing, ceramics, paper and cosmetics.
Package 25kg paper bags with liner inside.
