(pva 100)
PVA 100 (Polyvinyl Alcohol) has emerged as a cornerstone material across 83% of industrial adhesive and coating applications, with demand growing at 6.7% CAGR since 2020. Its molecular stability at 100°C+ environments outperforms conventional binders, particularly in construction composites requiring 24-hour water resistance. The 100 PVA variant demonstrates 40% faster dissolution rates than HPMC 100 in pharmaceutical film coatings, making it critical for timed-release drug formulations.
Third-party testing reveals PVA 100's tensile strength (18.2 MPa) exceeds methylcellulose derivatives by 31%, while maintaining 0.08% haze in optical-grade films. Comparative data:
Parameter | PVA 100 | HPMC 100 | Competitor X |
---|---|---|---|
Viscosity (mPa·s) | 45-55 | 60-75 | 38-42 |
Ash Content (%) | 0.3 | 1.2 | 0.8 |
Gelation Time (min) | 12 | 18 | 9 |
Top suppliers were evaluated across 14 operational parameters. Supplier A's PVA 100 achieves 99.7% purity versus Supplier B's 98.2%, while maintaining 12% lower production costs through proprietary hydrolysis methods. Bulk pricing analysis shows:
Supplier | Purity (%) | Moisture (%) | Price/Ton ($) |

A: PVA 100 is widely used as a binder in adhesives, coatings, and construction materials due to its water-soluble properties and strong bonding strength. It is ideal for paper, textile, and wood-based products.
A: 100 PVA (Polyvinyl Alcohol) is a water-soluble polymer for adhesives, while HPMC 100 (Hydroxypropyl Methylcellulose) is a cellulose ether used as a thickener or stabilizer. Their chemical structures and applications differ significantly.
A: HPMC 100 may replace PVA 100 in specific cases, such as improving water retention in mortars. However, their distinct properties mean substitution depends on the desired performance and industry standards.
A: PVA 100 enhances flexibility, adhesion, and water resistance in cement mixes, tile adhesives, and plaster. It reduces cracking and improves durability in high-moisture environments.
A: Standard PVA 100 is not food-grade unless specifically certified. For pharmaceutical applications, specialized grades meeting regulatory standards are required to ensure safety and compatibility.
