What are PVA glues characteristics?
What are PVA glues characteristics?
PVA adhesives produce clear, hard films that have good weather resistance and withstand water, grease, oil, and petroleum fuels. Additional properties are high initial tack, almost invisible bond line, softening at 30–45 °C, good biodegradation resistance, poor resistance to creep under load, and low cost.
What are the three main characteristics of PVA glue?
Properties of PVA Glue
- Suitable for porous materials. One of the distinguishing characteristics of PVA is that it is readily absorbed by porous materials.
- Water-soluble.
- Non-acidic.
- Remains clear and flexible when dry.
- Non-toxic (if not ingested)
- Odorless.
Is there different types of PVA glue?

What is polyvinyl acetate adhesive?
Polyvinyl acetate, also known as PVA or PVAc , is a synthetic polymer, or plastic. It is more specifically categorized as a thermoplastic, meaning it melts at high temperatures, and has certain properties such as being elastic and flexible at room temperature. Polyvinyl acetate adhesive is glue containing this compound.
