Low gloss capstock |
| 摘要 |
A low gloss capstock compound is disclosed. The combination of gloss inhibiting agents and polyolefin elastomer added to conventional polyethylene polymer resin achieves a gloss angle at 85° of below 10 GU. Optionally, the compound can also include weathering agents to improve outdoor durability. The compound can be fully formulated or a masterbatch for let-down into polymer to form the fully formulated compound. |
