Q1: What is Lubrizol TPU 2363-90AE primarily used for?
A: Lubrizol TPU 2363-90AE is a thermoplastic polyurethane-based additive designed to enhance melt processability, surface finish, and low-temperature flexibility in TPU and other polar polymer systems—commonly applied in extrusion, injection molding, and calendering of high-performance elastomeric compounds.
Q2: Is TPU 2363-90AE compatible with non-TPU polymers?
A: It exhibits good compatibility with other polar engineering thermoplastics such as polyester (PBT, PET), polyamide (PA6, PA12), and certain thermoplastic copolyesters—but compatibility should be verified experimentally in the target formulation due to sensitivity to polarity, molecular weight, and processing conditions.
Q3: How is TPU 2363-90AE typically incorporated into a compound?
A: It is generally introduced during compounding via twin-screw extrusion or dry blending prior to melt processing. Due to its thermoplastic nature, it melts and disperses readily at standard TPU processing temperatures, requiring no pre-drying under typical ambient storage conditions.
Q4: Does TPU 2363-90AE affect the mechanical properties of the base TPU?
A: At recommended use levels, it maintains or slightly improves elongation and low-temperature impact performance while modestly reducing tensile modulus—effects are formulation-dependent and generally balanced to support enhanced processability without compromising key end-use functionality.
