Q1: What is the primary function of Teelorex MD-300 TPE in thermoplastic elastomer formulations?
A: Teelorex MD-300 TPE is a processing aid and melt-flow modifier designed to enhance extrudability, reduce die swell, and improve surface finish in TPE compounds—particularly in SEBS- and TPO-based systems.
Q2: Is Teelorex MD-300 TPE compatible with common polymer matrices such as PP, PE, and SEBS?
A: Yes—it demonstrates good compatibility with polyolefin-based TPEs (e.g., TPOs), styrenic block copolymers (SEBS, SBS), and certain functionalized polyethylene grades. Compatibility should be verified under actual processing conditions due to formulation-specific variables.
Q3: How is Teelorex MD-300 TPE typically incorporated into compound formulations?
A: It is generally introduced during the compounding stage—either via side-feeding or masterbatch dilution—and disperses readily under standard twin-screw extrusion conditions. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight.
Q4: Does Teelorex MD-300 TPE affect the final mechanical properties of TPE products?
A: When used within recommended dosage levels, it maintains key performance attributes—including tensile strength, elongation at break, and hardness—while improving process efficiency. Significant over-dosing may impact crosslink density or phase morphology in dynamically vulcanized systems.
