Portable electronic device cover comprising renewable polyamide resin composition
View Patent ↗The invention discloses a portable electronic device cover comprising renewable thermoplastic polyamide compositions having a carbon content, wherein the carbon content comprises at least 50 percent modern carbon, as determined with ASTM-D6866 method.
1. A portable electronic device cover comprising a renewable thermoplastic composition comprising:
a) 70.1 to 100 wt % of at least one polyamide selected from the group consisting of polyamide 9,10; polyamide 9,12; polyamide 9,14; polyamide 9,16; polyamide 9,36; polyamide 6,10; polyamide 6,12; polyamide 6,14; polyamide 6,16; polyamide 6,18; polyamide 6,36; polyamide 10,10; polyamide 10,12; polyamide 10,13; polyamide 10,14; polyamide 10,15 polyamide 10,16; polyamide 10,18; polyamide 10,36; polyamide 10T/1010; polyamide 10I/1010; polyamide 12,10;and blends thereof; the at least one polyamide having a carbon content, wherein the carbon content comprises at least 50 percent modern carbon, as determined with ASTM-D6866 method;
b) 0 to 29.9 wt % of at least one fibrous reinforcing agent having circular type cross-section;
c) 0 to 14.9 wt % of at least one fibrous reinforcing agent having non circular type cross-section;
d) 0 to 29.9 wt % glass flake;
e) 0 to 29.9 wt % of at least one mineral reinforcing agent; and
f) 0 to 29.9 wt % of at least one impact modifier agent;
wherein the wt % of (a), (b), (c), (d), (e) and (f) are based on the total weight of the thermoplastic composition.
2. The device cover of claim 1 wherein the at least one polyamide is selected from the group consisting of polyamide 6,10; polyamide 10,10; polyamide 10T/1010; and blends thereof.
3. The device cover of claim 1 wherein the polyamide is polyamide 10,10.
4. The device cover of claim 3 wherein the polyamide has a carbon content of at least 90 percent modern carbon.
5. The device cover of claim 1 comprising 0.1 to 29.9 wt % fiberous reinforcing agent having circular type cross-section.
6. The device cover of claim 1 comprising 0.1 to 14.9 wt % fiberous reinforcing agent having non-circular type cross-section.
7. The device cover of claim 1 comprising 0.1 to 29.9 wt % of glass flake.
8. The device cover of claim 1 comprising 0.1 to 29.9 wt % of at least one mineral reinforcing agent.
9. The device cover of claim 1 comprising 0.1 to 29.9 wt % of at least one impact modifier agent.
10. The device cover of claim 1 wherein the at least one impact modifier agent is an ethylene-propylene-diene polymer grafted with 1 to 5 wt % maleic anhydride.
