Polyvinyl alcohol (PVA) injection molding particles
1, instant injection molding granule: used for the injection of educational toys (water mist magic beads), characterized by high dissolution rate in room temperature water, short solidification molding time.The instant material is also used in similar injection products that have the requirement of fast dissolution in room temperature water.
2, general injection molding granule: used for certain strength and toughness, dissolve in water at room temperature for a moderate time products, can also be applied to other similar requirements of injection products.
3. Medium and high temperature injection molding pellet: the products injected with this material are insoluble in water at room temperature and gradually dissolved in hot water above 55℃ (medium temperature) and 65℃ (high temperature).It can also be used for injection molding of various products in this water temperature range.
