THERMOPLASTIC ELASTOMER FOR OVERMOLDING ATTRACTIVE, PRACTICAL HANDGRIPS ONTO ABS RESIN © 2021, All Rights Reserved Avient Corporation, 33587 Walker Road, Avon Lake, Ohio USA 44012 To learn more about OnFlex-S™ TPEs, contact Avient at +1.844.4AVIENT (1.844.428.4368) or visit avient.com THE CHALLENGE Facing strong competition from all-plastic garden sprayers, a leading garden equipment manufacturer decided to create a new, high-end line of sprayers featuring enhanced quality, durability and aesthetics. The new products have been very well received by consumers, and have allowed the company to address the competitive threat from all-plastic sprayers. • Lower system costs = higher margins: By reducing waste from part deformation, the Avient TPE allowed the manufacturer to leverage efficient, fast 2K molding for system cost reduction. These savings help the company to achieve high margins on its top-of-the-line sprayers. • High-end product line = competitive advantage: With Avient’s OnFlex-S TPE, developers successfully designed and produced a new, high-end product line that compares favorably with all-plastic sprayers in terms of appearance, performance and durability. • Gripping feel = safety and usability for customers: Hand grips created from overmolded OnFlex-S TPE provide excellent anti-slip performance even when wet.

Mevopur™ Healthcare Functional Additives Laser Welding Additives for Medical Devices Laser welding has become a technology of choice to join plastic parts of complex medical devices. Also known as transmission welding, laser welding is the process of using focused laser radiation to bond two plastic parts, one that is transparent to the laser energy and one that absorbs the energy. Please be aware that there are certain applications Avient’s Mevopur products have not been designed for, nor are they promoted or intended for use in: including, but not limited to long-term or permanent implants, birth control devices, or plastic surgery.

This is achieved by molding a soft skin of thermoplastic elastomer over a hard engineering plastic. The TPE chemistry and the type of engineering plastic play a critical role in influencing wettability. The bond strength between the TPE and the engineering plastic was measured by performing a “90o Peel Test”.

While commodity plastics can typically maintain performance only up to 100°C, and engineering plastics do the same up to 120°C, a high-performance thermoplastic can withstand continuous use temperatures of 230°C while also maintaining low temperature impact. Automotive: Demand for plastics to handle increasing temperatures due to the proliferation of electronics in engine compartments and tighter spaces. Most high-heat plastics are hygroscopic, so careful drying is needed to avoid potential processing issues.
