PARALOID™ BPM-515

Acrylic based. Is specially designed to improve the impact resistance of polylactic acid (PLA) compounds while maintaining clarity for packaging applications. Improves the impact properties without sacrificing the transparency of the product. In addition to better impact properties, PLA modified with BPM-515 shows a marked reduction in brittle behavior during cutting and hole punching operations. All of this is accomplished at a lower loading level of the acrylic modifier thus making PARALOID BPM-515 Acrylic Impact Modifier a more sustainable and lower use cost solution. Acrylic impact modifiers similar to PARALOID™ BPM-515 Acrylic Impact Modifier used at up to 5% loading levels have been found not to adversely effect the biodegradability of PLA as measured by ASTM D6400-04 per ASTM D5338. It results in clean cuts and resistance to unwanted cracking during processing. The combination of the nano-scale particle size and excellent dispersability of PARALOID™ BPM-515 in PLA, the addition of the modifier has minimal effect on the clarity of the PLA film. The higher efficiency of PARALOID BPM-515 Acrylic Impact Modifier compared to PARALOID BPM-500 translates to improved impact at a comparable haze level at lower addition levels. Is especially useful in applications where a balance between toughness and transparency is a key. These include thermoformed packaging applications, as well as industrial and consumer goods.
