Extrusion lamination is a process in which a molten thermoplastic resin is extruded through a flat die and used as an adhesive layer to bond two or more substrates together. Instead of using solvent-based or water-based adhesives, the molten polymer itself acts as the bonding medium. The extruded resin is applied between substrates and immediately pressed together through a chill roll and pressure nip, forming a strong laminated structure. In practice, this means laminating barrier films , Aluminum Foil, Met-BOPP, Met-BOPET to printed bi-oriented films like BOPP, BOPET, and BOPA, then sealing with PE/PP webs. The process runs at 320–330°C using a high-flow LDPE resin (MFI 6–8), typically blended at 6–25% with specialty adhesion polymers (acrylate or POE based) to guarantee adequate bonding. 🔶 Introducing TL 4114 - Polyram's direct replacement.

KCC Silicone has initiated a regular technical exchange program with the Robotics Institute at Seoul National University (SNU RI) to advance the development of silicone materials for robotics applications. On July 14, KCC Silicone hosted the inaugural Robotics Technology Exchange Seminar at its R&D Center in Giheung-gu, Yongin, South Korea. The event brought together Professor Yongrae Park's research team from the SNU Robotics Institute, along with researchers and technical specialists from both organizations. Approximately 20 participants attended the seminar, where they shared the latest research and technical expertise on silicone materials for robotics. Key topics included silicone polymer compounding technology, which enables customized material properties such as elasticity, strength, and durability by optimizing polymer formulations for specific applications, as well as the use of silicone materials in soft actuators—flexible actuation systems that mimic the contraction ...

It’s material separating from the main melt stream and refusing to release cleanly at the die exit. When polymer starts building up, smearing, or burning around the die lips, it means one thing, the melt and the metal are no longer in agreement and you can’t just wipe it. If you try, you’ll do exactly what I did which is tear the sheath, mark the surface, or turn a nuisance into scrap. That’s because die drool isn’t loose material sitting there politely. It’s partially degraded polymer anchored to the die lip, fed continuously by whatever imbalance exists upstream. Most of the time, the cause is one or more of these; • localized shear overheating near the die exit • die temperature slightly mismatched to melt viscosity • poor melt homogeneity from screen pack or backpressure • additive or plasticize...

When dealing with porous substrates—like specialized acoustic foams, unsealed metals, or composite plastics—surface-level adhesion is a guarantee of future delamination. Most standard tapes are too viscous. They sit flat on top of the microscopic craters, leaving 60% of the actual surface area completely untouched. The secret to structural longevity here is "wicking." By modifying the adhesive's rheology (its flow characteristics), we can ensure it deeply penetrates into the microscopic pores of the substrate before it fully sets. Instead of just relying on chemical tack, the adhesive creates thousands of microscopic physical anchors. This "mechanical interlocking" is what turns a temporary surface grip into a permanent, structural bond. If your tapes are peeling of...
