1、 Product performance
1. Product Introduction
Starch is a natural macromolecule and polysaccharide type biopolymer, but the processing and melting temperature of starch is greater than its decomposition temperature. It is necessary to modify natural starch through various environmentally friendly additives to achieve melting like processing plastic. The difficulty of controlling the entire melting process is high, the pressure should not be too high, the temperature should not be too high, and the residence time should be appropriate. By precise control, this product can be processed.
2. The appearance color is a transparent light yellow with a slight fragrance and sweet taste. The product density is 1.5. The logistics performance of the product is close to LLDPE. Suitable for various biodegradable polymer melt alloys, capable of producing various degradable materials, not limited to disposable tableware and packaging materials. In terms of processing methods, the process can be completed through injection molding, suction molding, blow molding, film blowing, and other methods. At present, TPS thermoplastic starch has gradually gained recognition from everyone, but TPS itself also has shortcomings. For example, water resistance issues and recrystallization issues. Dispersion issues, temperature control issues. If these problems can be solved or improved, it is equivalent to solving the common pain points in the field of biodegradation. Our R&D personnel are also committed to addressing the shortcomings of TPS thermoplastic starch. It was found that thermoplastic starch undergoes multiple modifications. It has achieved certain improvements in its water resistance, retrogradation, and temperature resistance.
3. Practical application of the product
TPS thermoplastic starch can be produced by melting alloys with petroleum based polymers, such as starch+pp, starch+PE, etc., which can reduce the consumption of petroleum while also degrading it to a certain extent. TPS thermoplastic starch can be melted with biodegradable materials to produce disposable fully degradable products, including film blowing, blistering, and injection molding. And the melting performance is very good and stable, and ordinary screws can also complete it. In terms of adhesives, thermoplastic starch exhibits excellent physical properties.
4. Precautions for product use
Thermoplastic starch has strong hygroscopicity, and our factory packaging uses vacuum plastic packaging. If the bag is found damaged or unpacked, it must be dried and used at a temperature less than 100 degrees Celsius.
