There are several biobased polymers that can be used for fiber reinforcement, including:
- Cellulose: Cellulose fibers can be derived from wood, cotton, or other plant-based materials. They are widely used as a reinforcement fiber in polymer composites due to their high strength and stiffness, low weight, and biodegradability.
- Polylactic Acid (PLA): PLA is a biodegradable polymer that can be derived from cornstarch, sugarcane, or other biobased feedstocks. It has good strength and stiffness properties and can be used as a reinforcement fiber in composites.
- Polyhydroxyalkanoates (PHA): PHAs are a family of biodegradable polymers that are produced by bacteria from renewable resources such as vegetable oils or sugars. They have good mechanical properties and can be used as a reinforcement fiber in composites.
- Starch: Starch can be derived from corn, wheat, or other plant-based materials. It is a biodegradable and renewable resource that can be used as a reinforcement fiber in composites.
- Soy protein: Soy protein can be used as a biobased reinforcement fiber in polymer composites. It has good strength and stiffness properties and is renewable and biodegradable.
These biobased fibers can be used to reinforce a variety of polymers, including thermoplastics, thermosets, and elastomers, to create strong, lightweight, and sustainable materials.
How can VAE help within these applications?
VAE is a watersolluble, thermoplastic polymer, that is often used as a binder for adhesives and coating purposes.
VAE may help starches to be more water resistant, and many biopolymers can benefit from more ductility, flexibility and adhesion strength. VAE can be available as biobased (based on bio-ethylene and BIO-VAM( BIO-acetic-acid + bioethylene). Being good watersolluble and thermoplastic, VAE has good properties for compostability and recycling purposes.
Is VAE a water solluble polymer?
Vinyl acetate ethylene (VAE) is a water-based polymer emulsion, meaning that it is dispersed in water rather than being a solid polymer. When VAE is dispersed in water, it forms a colloidal suspension that is stable and can be used in various applications.
However, VAE is not completely water-soluble. While it is dispersible in water, it does not fully dissolve in water like a soluble salt or sugar. Instead, the individual particles of VAE remain suspended in the water.
This property is actually beneficial for many applications, as it allows VAE to be easily mixed with other water-based materials, such as pigments, fillers, and other polymers, to create a variety of products like paints, adhesives, and coatings.
