說明書
For example, the composite material wherein component A is at least one semi-crystalline polymer resin, shows an elongation at break of at least 5% as determined according to ISO 527-1; preferably of at least 8%, more preferably of at least 10%. For example, the composite material wherein component A is at least one semi-crystalline polymer resin, shows an elongation at break ranging from 5% to 25% as determined according to ISO 527-1; preferably from 8% to 20%, more preferably of at least 10% to 18%.
Component a being a Polymer Resin
Component A is a polymer resin that is at least one amorphous polymer resin or at least one semi-crystalline polymer resin selected from polyethylene resin and/or polypropylene resin.
For example, component A is present in the composite material at a content ranging from 35 to 80 wt. % based on the total weight of the composite material; for example, from 38 to 78 wt. %; for example, from 40 to 75 wt. %; for example, from 45 to 70 wt. %; for example, from 50 to 65 wt. %.
For example, component A is present in the composite material at a content of at least 35 wt. % based on the total weight of the composite material; for example, of at least 38 wt. %; for example, of at least 40 wt %; for example, of at least 45 wt. %; for example, of at least 50 wt. %.
For example, component A is present in the composite material at a content of at most 80 wt. % based on the total weight of the composite material; for example, of at most 78 wt. %; for example, of at most 75 wt. %; for example, of at most 70 wt. %; for example, of at most 65 wt. %.
For example, component A is selected from a virgin polymer resin, a post-consumer polymer resin and a blend of a virgin polymer resin and a post-consumer polymer resin.
