HOW GLS TPES MAKE THE DIFFERENCE IN INFANT CARE APPLICATIONS • Safe to Use – Made without bisphenol A (BPA), phthalates, or heavy metals; select grades compliant with FDA, REACH and China GB4806 • Durable – Resists bites and tears; many are tested and safe to use in microwaves and dishwashers • Comfortable – Can be overmolded to provide a soft touch grip and customized to specific comfort requirements including vibration and noise reduction • Easy to Process – Can be injection molded and overmolded right onto a substrate including PP, ABS, etc

We use our proven expertise in formulating high temperature thermoplastics to create formulations based on materials that include: • PEEK • PSU • PEI • LCP • PES • PPS • PPSU These specialty formulations give manufacturers confidence in the reliability and durability of their products.

Specifically, these additives have been proven to be effective inhibiting E. coli and MRSA across these resins: • TPE/TPU • PET • HDPE • ABS • POM • PP • PC Custom formulations can be validated for various resin types, and under specific processing conditions, at an independent testing lab to ensure results in commercialization.

*** Pro forma for sale of Performance Products and Solutions segment (PP&S).

Compared to rubber and silicone alternatives they simplify manufacturing with single-step fabrication, reducing the energy used in production and can be overmolded directly onto non-polar polymer substrates such as polypropylene (PP) and polyethylene (PE).

To answer these, we will look at five different material families: • Polyaryletherketones (PAEK) • Polysulfones (PSU) • Liquid crystal polymers (LCP) • Polyetherimides (PEI) • Polyphenylene sulfides (PPS) Read on to discover the diverse and growing uses for these elite-level performers of the thermoplastic world. They include PPS, PAEKs and LCPs. However, these high- heat materials require much higher mold and melt temperatures than typical plastics such as polypropylene (PP), nylon and polycarbonate (PC).
