Environmental Protection Polybutylene Succinate Pbs Decomposable
The main purpose
Used in the food industry as a flavoring agent, feed additive, reagent for laboratory analysis, using only industrial intermediates. Flavoring agents, sour agents, and buffers are mainly used in the preparation of hams, sausages, aquatic products, and seasoning liquids.
Product Features
White particles, density 1.26g/cm, melting point 114°C, crystallinity between 30~45%; milky white, odorless, easy to decompose.
Bio-based polybutylene succinate (PBS) is a typical fully biodegradable polymer.
Molding method
Polybutylene succinate (PBS) is a thermoplastic resin and has good processing properties. It can be processed on ordinary processing equipment. The processing temperature range is 140~260°C. The material must be dried prior to processing. The moisture content must be below 0.02%.
Polybutylene succinate (PBS) can be processed by injection molding, blow molding, blown film, blister, lamination, foaming, spinning and other molding methods.
Polybutylene succinate (PBS) is a polymer with good biodegradability. Compared with polylactic acid, polyhydroxyalkanoate, polycaprolactone and other biodegradable plastics, PBS is relatively low in price. Excellent mechanical properties, good heat resistance, heat distortion temperature close to 100 °C.
