Selvol E PVOH Grade Families at a Glance
Selvol E PVOH performance depends on the balance between hydrolysis and viscosity (molecular weight). Use these summaries to align grade characteristics with your process needs.
Degree of Hydrolysis
Hydrolysis levels influence final moisture resistance, solubility and chemical stability of the PVOH film:
- Fully hydrolyzed grades (98.0%–98.8%) provide strong water and grease resistance. They often suit paper surface sizing and moisture-resistant adhesives.
- Partially hydrolyzed grades (87.0%–89.0%) dissolve more easily at lower temperatures and offer increased flexibility. They support applications from textile finishing to PVC production.
Viscosity and Molecular Weight
Viscosity ranges in the Selvol E PVOH line correlate with polymer chain length and affect film strength and rheology:
Applications and Industrial Uses
The Selvol E PVOH line supports a broad range of industrial applications across adhesives, paper, textiles and specialty manufacturing.
Paper and Specialty Coatings
Manufacturers use these grades for surface sizing, pigment coating and anti-grease treatments. Specialty uses include functional layers for thermal paper, carbonless paper and release liners.
Textile Processing
The Selvol E PVOH line supports cotton and synthetic yarn sizing to improve weaving performance. Certain grades also support nonwoven finishing and provide the abrasion resistance needed in high-speed textile operations.
Specialized Industrial Applications
Selvol E PVOH serves several vital roles in specialty manufacturing:
- Acts as a temporary binder in ceramics and specialty coatings
- Functions as a secondary stabilizer in PVC and polystyrene production, helping control particle porosity
- Provides a base material for water-soluble films and microencapsulation systems
FAQ: Selvol E PVOH
Find answers to common customer questions about Selvol E PVOH grades.
How does Selvol E PVOH differ from other Selvol grades?
Selvol E PVOH grades share many core PVOH characteristics with global Selvol products. However, we manufacture Selvol E PVOH in Europe, and grades aren’t always one-to-one interchangeable with other Selvol grades. Compare viscosity, hydrolysis, solution behavior and local availability before switching between Selvol PVOH and Selvol E PVOH grades.
When should I choose Selvol E PVOH products?
Selvol E PVOH products often suit European plants that prefer regional manufacturing and supply. They also support global customers who run European production or need grades aligned with European regulatory and sourcing requirements.
How does Selvol E PVOH relate to sustainability goals?
Many customers consider Selvol E PVOH part of broader sustainability and sourcing strategies. Regional manufacturing can support logistics planning and help align with internal goals for European supply chains. Review your own sustainability criteria and discuss options with SEKISUI technical and commercial teams.
