What is PVA Mould Release Film?
PVA Mould Release Film is a water-soluble, eco-friendly release layer designed for high-precision molding processes.
It forms a uniform barrier between mold and material, enabling easy demolding, superior surface finish, and zero residue contamination.
Unlike traditional oil-based release agents, PVA release film dissolves completely in water, eliminating cleaning costs and environmental risks.
Key Advantages
1. Perfect Demolding Performance
- Prevents adhesion between mold and substrate
- Reduces breakage and deformation during demolding
2. Residue-Free & Water Soluble
- Fully dissolves in water
- No secondary cleaning required
3. Superior Surface Finish
- Creates smooth, defect-free surfaces
- Ideal for decorative and high-end applications
4. Eco-Friendly Alternative
- Replaces oil, wax, and chemical release agents
- Non-toxic, biodegradable solution
5. Cost Efficiency
- Reduces labor + cleaning time
- Improves production consistency

FAQ
1. Is PVA mould release film suitable for concrete molds?
Yes. It is widely used in precast concrete and GRC molds to improve surface quality and reduce defects.
2. How does it compare with liquid release agents?
PVA film provides uniform coverage, avoids uneven coating, and leaves no residue.
3. What is the dissolution time?
Depends on thickness and temperature, typically 30–240 seconds in water.
4. Can it be customized?
Yes. Thickness, width, and dissolution speed can be tailored for different molding systems.
5. Is it environmentally friendly?
Yes. It is water-soluble, biodegradable, and non-toxic, replacing oil-based systems.
