Ravago Compounds HM-286 LDPE
Product Description |
HM-286 is an antioxidant concentrate used to fortify heat and process stability, where the stabilizers contained in the resin are insufficient for the process or application. This concentrate is also useful as a shutdown/purge compound for operations that do not operate continuously. Key Features: Uniform concentration of additives in concentrateEase of addition and feeding into extrusion equipment Directions for Use: Antioxidant Concentrate: HM-286 is normally added to polyethylene at 1 to 2% to increase oxidative stability, reduce tendency for gel formation, etc. Shutdown Purge: Before shutdown, the extruder should be cooled down and purged using 100% HM-286 until the HM-286 comes through the die. The extruder should be shut down with the HM-286 in the flow channels. This will prevent oxidation of the polymer in the equipment during shutdown. In many cases HM-274 is a more efficient purge. This product contains a mild scouring agent to clean the metal surface of discolored or pigmented materials. |

LDPE性能与介绍
LDPE受热后,随温度升高,结晶逐渐减少,结晶部分完全消失,聚乙烯就融化,此时的温度为熔点。聚乙烯的密度升高,结晶度升高,熔点也随升高,所以密度不同聚乙烯,其熔点不同。LLDPE的熔点为120~125℃,于H P-LDPE与HDPE之间。共聚单体的LLDPE,熔点高低随其共聚单体的碳原子的增减而变动,碳原子数增多熔点升高。由LLDPE熔点比H P-LDPE高,模型制品在较高温度下脱模,又快又干净。因LLDPE熔点范围比H P-LDPE,
LLDPE薄膜,热合强度高。
LDPE在温度升高时的流动性和在增加荷重时的变化,主要受分子量的影响。由于测定聚乙烯的熔体流动速率比测定分子量容易,因而通常以熔体指数(MI),或熔体流动指数(MFI)来表示聚乙烯的分子量特性。在熔融状态下,LDPE熔体粘度是分子量函数,随分子量增高加大。分子量相同,温度升高熔体粘度降低。常温下LDPE密度有不同韧性。低温LDPE自然有良好韧性,脆析温度较低,与分子量有关。LDPE分子量增高,温度下降,值为-140℃。分子量相同情况下,线型结构的LLDPE与HDPE的熔体粘度要比非线型结构的H P-LDPE大。熔体指数相同情况下,H P-LDPE的熔体粘度明显低于LLDPE和HDPE,前者加工时的熔体流动性明显好后两者,螺杆负荷小,发热量也小。
