Differences between PVA 088-13 and PVA 1388

Both PVA 088-13 and PVA 1388 are partially alcoholyzed polyvinyl alcohols, with a degree of alcoholysis of approximately 88%. However, their degrees of polymerization differ: 088-13 has a lower degree of polymerization, while 1388 has a higher degree. Consequently, their properties and uses differ slightly.

Applications of PVA 088-13
Pharmaceutical and Daily Chemicals: This non-toxic product can be used as a granulating agent for pharmaceuticals and pesticides, as an adhesive for bandages, as a thickener for eye drops, and as a material for medical hot compresses. Its excellent emulsifying properties, film-forming properties, and moderate viscosity make it suitable for emulsifying oil emulsions. It can also be used as a primary ingredient in cooling creams, cleansing creams, skin care creams, and facial masks.

Textile Industry: It is easily soluble in water, allowing for easy sizing. The sizing agent adheres tightly to the fibers, reducing thread breakage during fabric processing, improving work efficiency and increasing product quality. It is easy to desize and operate, making it particularly suitable for warp yarn sizing.

Paper Industry: It can be used for sizing and reinforcing the surface of paper, improving its toughness, smoothness, and water resistance, resulting in high-quality and durable paper. It can also be used in the production of specialty papers such as filter paper and battery separator paper.

Agriculture and Forestry: It can be used as a binder in compound fertilizers, ensuring even fertilizer distribution. It also improves soil structure, increases granularity, facilitates air permeability, and retains water.

Applications of PVA 1388
Construction: It can be added to dry-powder glue, dry-powder putty, dry-powder mortar, and oilfield cementing, increasing flexibility, water retention, reducing friction, and improving work efficiency and quality. It also produces a smooth, strong, and resistant plaster layer that resists cracking and peeling.

Adhesive: It has high viscosity and strong bonding strength, making it suitable for making woodworking glue and adhesives for paper products, meeting bonding requirements.

Packaging Industry: It has excellent film-forming properties and barrier properties, making it suitable for producing high-barrier packaging films for food and medicine packaging, extending product shelf life.

Pharmaceutical Industry: It can be used as an excipient for tablets, capsules, and oral films. Its high viscosity aids in drug formation and controlled release.
