Why Choose a Mold Release PVA Water Soluble Film?
Advantages and Applications
1. Good release performance; producing rough embryos after stripping is difficult, saving grinding time.
2. It has high softness and smoothness, making PVA film fit the mould better, and the release quality is higher.
3. Good heat resistance: can heat up to 180 degrees.
4. Good mechanical properties: high tensile strength and elongation at break.
5. Suitable for continuous production and high production efficiency.
It can usually be used as a release film of artificial marble, silicone elbow, bellows, and artificial limbs (epoxy plastic resin and unsaturated plastic resin). And it can be cut into required specifications according to customer requirements.

Frequently Asked Questions
High-temperature PVA mold release film is a special type of high-transparent water soluble film, which is mainly using polyvinyl alcohol as the substrate with specialized additives that enhance properties like heat and chemical resistance. And they are usually used as the demould films of artificial marble due to it’s excellent mechinical properties, such as high heat resistance,high tensile strenght, high tear strength, high elongation at break, less shrinkage, and so on.
High-temperature mold release PVA has many industrial applications due to it’s high heat resistance and excellent chemical and mechnical properties.
High-temperature PVA film is used as the release medium in the manufacturing process of some products ,such as the demould films of artificial marble, quartz,prosthetics, plaster mold, etc. It is easy to release the mold since it is high heat resistant and won’t be melted by the high temperature of the casting solution. After the demoulding is completed, the PVA film can be dissolved in hot the water or dealt with by composting , thus it can effectively improve the surface quality of the products, improve the production efficiency and is benefit to the environment.
The best way to remove high-temperature mold release PVA is simply by dissolving it in water which will quickly cause it to break down into harmless components without leaving any residue behind.
Yes, mold release films are generally safe to use and have significant advanges over regular mold release films.
Firstly, they are water soluble and biodegradable,and they can be dissolved in water or decomposed into natural substances by anaerobic microorganisms .
Secondly, the films have good detachment performance and are not easy to produce burr after release. This helps to save sanding time .
Thirdly , the PVA films have high softness and excellent smoothness, it can make the release film fit the mold better, thus to get great release quality.
Fourthly , they can be heat resistant up to be around 180℃ due to their excellent high temperature resistance.
Fifthly, they have good mechanical property, like high tensile strength and elongation at break .
Sixthly, they are suitable for continuous production, this helps to improve the production efficiency. So, they are especially suitable for large-scale production of artificial marble, quartz, and so on.
In summary, the PVA mold release films areare non-toxic and non-hazardous , they won’t pose any health concerns once they are used properly. Also, they have many advantages when used in mold release production.
Yes, the PVA mold release films are eco-friendly.
First, the film is made from water soluble material PVA or PVOH , this material does not contain any harmful chemicals or pollutants. So the PVA mold release films won’t lead to any harmful effect to the environment during their whole production and usage.
Second, the films are biodegradable and compostable besides the water solubility. When you don’t need them any more, and if they can be dealt with properly, they won’t be harmful to the environment .
There are some ways to deal with the wasted PVA demould films , one is to dissolve in the suitable temperature’s water, the second is to handle them by composting way , the third is to burry them into the soil . Whichever ways you choose, they can be broken down into non-toxic and harmless matters finally.
From all of these , it can be seen that the PVA demold film won’t harm the environment and is fully eco-friendly .
