PLA injection molding grade resin

In PLA injection molding market applications, the more widely used is the modified resins. Although pure PLA has high transparency, ferrous lactate, etc., but its hard and brittle, difficult process and does not affect its heat and other shortcomings in the application of injection molding. Of course, the chemical, plastics industry are committed to solve these problems. For example, using the BPM-500 This additive can improve the impact strength of PLA; adding a small amount called Biomax Strong vinyl copolymer can improve the toughness of the PLA; with another PHA biodegradable resin blends can improve some of the PLA performance; addition, Japanese Scientists then developed a heat-resistant PLA resin pulp added. Some of the ways the above polylactic acid modified products at the expense of the transparency, but it improves the heat resistance of polylactic acid, buffered lactic acid, impact resistance and other aspects of defects and improve the ease of its processing, the application range been expanded. In injection molding grade resin sea is about 70% of sales for the modified polylactic acid.
And on the whole, relatively high cost is impeding PLA widely used in the injection molding market, the biggest reason. Although pure resin modified by filling in some of the cost can be reduced, but to ensure its performance under the premise of the role of this measure is limited, if you need to, under the premise that biodegradable PLA improve performance deficiencies, such as heat performance, cost is even higher.
