Natur-Tec® BF3002HT
Natur-Tec® BF3002HT is a bio-based and compostable, impact modified, highly filled polymer masterbatch made with Ingeo™. It is intended for injection molded PLA applications that require high heat. BM3002HT is designed to be blended with virgin Ingeo™ grades where the final blend is molded either in (1) a single-step using in-mold crystallization at much reduced cycle times and minimum part warpage (BF3002IM) or (2) in a two-step economical process where parts are crystallized in a secondary oven (BF3002HT) .

- Benefits
A key advantage of this blend is that the resin going through two heat histories is limited to the percent (%) masterbatch letdown (typically 15-50%). This helps maintain the molecular weight, resulting in improved mechanical strength for the final part, as compared to a part manufactured with the 100% fully-compounded resin. Natur-Tec resins are engineered for high performance.
- Application
Natur-Tec® BM3002HT when blended with Ingeo™ at 15-50% can be used for injection molded plastic applications requiring high heat performance such as cutlery and coffee stir sticks.
