BLACKlineHHP is the first BLACK vinyl fence that is designed for high temperature performance. Previous dark colored plastic fence materials have not had the advantage of our unique high temperature thermoplastic formulations which eliminate the sag and distortion tendencies often found in other dark plastic fencing products. Additionally, our knowledge base relating to color stability of black thermoplastic material has allowed us to formulate a black fencing products without fading or chalking issues. The secret is using the right colorant in the right amounts, along with UV inhibitors making fading and chalking a non-issue.
