Laripur® 4760 is a polytetramethylene glycol (PTMG) polyether-based thermoplastic polyurethane (TPU) known for its excellent resistance to hydrolysis and microbial attack. The standard version of this TPU is specifically formulated for injection molding applications, making it well-suited for the production of technical items. Additionally, there is another version tailored for extrusion processes, allowing for the manufacturing of hoses, cables, profiles, and films. The versatility of Laripur® 4760 makes it suitable for a range of applications that demand resilience and durability.

Polymer Name: Thermoplastic Polyurethane (Polyether based)

Processing Recommendations

Material needs to be dried prior processing at 175-195 °F for 3 hours, preferably using a dehumidifying drier fed by air exhibiting a dew point lower than -22°F.
Suggested molding temperature profile:

Zone Temperature
Zone 1 365°F
Zone 2 375°F
Zone 3 385°F
Nozzle 375°F

Suggested extrusion temperature profile:

Zone Temperature
Zone 1 375°F
Zone 2 380°F
Zone 3 390°F
Zone 4 385°F
Adapter 375°F
Die 365°F

 

Being affected by type of machine used, processing conditions and downstream equipment, the temperature profiles as given above has to be considered as just indicative.
