Q1: What is the primary function of Kraiburg E OC6OAZ TPE in thermoplastic elastomer formulations?
A: Kraiburg E OC6OAZ TPE is a functional additive designed to enhance melt processability and improve surface finish in TPE compounds, particularly in dynamic vulcanized TPV systems. It supports better dispersion of fillers and stabilizes morphology during extrusion or injection molding.
Q2: Is Kraiburg E OC6OAZ TPE compatible with common TPE base polymers such as SEBS, TPO, and TPV?
A: Yes, it demonstrates broad compatibility with styrenic block copolymers (e.g., SEBS), polyolefin-based TPOs, and dynamically vulcanized TPVs. Compatibility should be confirmed experimentally for specific polymer blends and processing conditions.
Q3: How is Kraiburg E OC6OAZ TPE typically incorporated into a TPE formulation?
A: It is generally introduced during the compounding stage—either pre-blended with other additives or added directly to the extruder feed throat. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight relative to the total compound.
Q4: Does Kraiburg E OC6OAZ TPE affect the final mechanical properties of the TPE compound?
A: When used within recommended dosage ranges, it does not significantly compromise tensile strength or elongation at break. In many cases, improved dispersion leads to more consistent mechanical performance across batches.
