Teknor Apex entered the dropper bulb industry several decades ago with Monprene® MP-2840E, a specially formulated thermoplastic elastomer (TPE) that could mimic the haptics and elasticity of rubber. Since then, Teknor Apex’s portfolio of medical TPEs expanded under the Medalist® brand, and the MP-2840E evolved into Medalist MD-12344, a cleaner compound with fewer additives for even lower extractables. Currently, this material is the premier choice by molders and OEMs alike for dropper bulb applications.
Medalist MD-12344 is resistant to acids, bases, and solvents and is suitable for both glass and plastic pipettes. With very low permeability and excellent resistance to UV, MD-12344 allows dropper bulbs to better preserve the product’s shelf life. Medalist TPEs are available in pellet form, in a light natural color or can be custom colored per your requirements.
