Abstract

A molding composition includes, by weight, 40% to 80% of polypropylene, up to 50% of glass fibers, up to 40% of cellulose fibers, up to 50% of basalt fibers, and 4% to 12% of additives.

Claims

1. A molding composition comprising, by weight, 40% to 80% of polypropylene, 5% to 50% of glass fibers, 5% to 40% of cellulose fibers, and 4% to 12% of additives.

2. The molding composition as recited in claim 1, wherein, by weight, the amount of glass fibers is greater than the amount of cellulose fibers.

3. The molding composition as recited in claim 2, wherein the glass fibers are 20% to 50%.

4. The molding composition as recited in claim 1, wherein the glass fibers are 5% to 20%.

5. The molding composition as recited in claim 1, wherein the glass fibers are 20% to 40%.

6. The molding composition as recited in claim 1, wherein the glass fibers are 35% to 50%.

7. The molding composition as recited in claim 1, wherein the cellulose fibers are 20% to 40%.

8. The molding composition as recited in claim 1, wherein the cellulose fibers are 5% to 20%.

9. The molding composition as recited in claim 1, wherein the cellulose fibers are 10% to 30%.

10. The molding composition as recited in claim 1, wherein the molding composition is in the form of pellets.

11. A molding composition comprising, by weight, 40% to 80% of a thermoplastic selected from polypropylene, polyamide, and polybutylene terephthalate, 5% to 50% of basalt fibers, and 4% to 12% of additives.

12. The molding composition as recited in claim 12, wherein the basalt fibers are 5% to 20%.

13. The molding composition as recited in claim 12, wherein the basalt fibers are 25% to 50%.

14. The molding composition as recited in claim 12, wherein the basalt fibers are 15% to 30%.
