Q1: What is the primary function of Teelorex MP-1876 TPE in thermoplastic elastomer formulations?
A: Teelorex MP-1876 TPE is a functional additive designed to enhance melt processability and improve surface finish in TPE compounds, particularly in styrenic (TPE-S) and olefinic (TPO/TPV) systems. It helps reduce extrusion torque, lower die swell, and promote uniform dispersion of fillers and pigments.
Q2: Is Teelorex MP-1876 TPE compatible with common polymer matrices used in soft-touch applications?
A: Yes — it demonstrates good compatibility with SEBS, SBS, PP, PE, and EPDM-based TPEs. It is especially effective in multi-layer coextrusions and overmolding applications where interfacial adhesion and surface clarity are critical.
Q3: How should Teelorex MP-1876 TPE be incorporated into a compound?
A: It is typically introduced during the masterbatch or final compounding stage via twin-screw extrusion. Pre-drying is not required, but for optimal dispersion, it is recommended to add it after base polymer melting and before filler introduction. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight.
Q4: Does Teelorex MP-1876 TPE affect the mechanical properties of the final TPE product?
A: When used within the recommended dosage range, it maintains tensile strength and elongation at break while often improving tear resistance and dynamic fatigue performance. Significant over-addition may reduce hardness or modulus, so optimization trials are advised for each specific system.
