Thermoplastic Elastomers (TPE)
Thermoplastic elastomers are rubber-like polymer materials processed via injection molding. This material is ideally suited to create fluid seals in mid to high volumes due to its cost efficiency. “Overmolding,” a technique used to injection mold TPEs onto rigid plastics (e.g., reagent caps, cartridge bodies, and flow cell chips), can replace secondary assembly steps with a more consistent production process and a stronger seal. Today, TPE fluid-sealing interfaces are used in many life science and bioprocessing applications for their high reliability and versatility.
Medical and Diagnostic Fluid-Sealing Applications
Enplas manufactures high-performance custom TPE fluid seals with challenging dimensions and requirements, including microfluidic chip-based technologies, for life-science market leaders and startups alike. Our products are used in applications such as in vitro diagnostics (IVD), next-generation sequencing (NGS), polymerase chain reaction (PCR), immunoassays, electrophoresis, single cell analysis, sample preparation, and pharmaceutical manufacturing.

TPE vs. Silicone What is the difference between the elastomers TPE and LSR? Which is more fit for my medical device? | Manufacturing Fluid Seals Design, material choice, and reliable manufacturing for consistent quality that prevents leakage no matter how high the volume. | TPE Bonding How does the elastomer bond with rigid plastics? Is the bond reliable? |
Motion and Sealing How do you ensure that the sealing is intact when motions may pull on the elastomer or cause friction? | Temperature and Sealing Can the TPE fluid seal withstand heat cycling for PCR? Or cryogenic storage? | Cost Efficiency Overmolding and effective DFM can improve cost efficiency when manufacturing TPE fluid seals. |
