Though the viscosity of TPEs are reduced when processed at high shear rates, TPEs must be “packed” into a mold to ensure complete fill-out. Hand tools, smartphone cases and razor handles are examples of products that benefit from using a combination of soft and hard textures to improve grip, add tactile sensation or cushion impact. Because LSR cures at high temperatures, using it as an overmold material in a two-component molding system requires pairing it with high temperature thermoplastics to overcome the risk of melting or deforming the substrate.

ColorMatrix AAzure has shown to have a much improved impact on the recycling process, with reduced yellowing through multiple heat histories. LD R (% Impact of 5 Melt Heat Histories on Preform Color Reference ColorMatrix AAzure Reduction in AA Level 35% 55% 70% ColorMatrix AAzure allows for further optimization of the polymer weight distribution during the bottle blowing process, which improves mechanical strength and bottle quality. This improves processability at high levels of rPET, reducing blowouts, improving productivity, allowing for higher levels of rPET use, and also lightweighting.

This translates to 6% adjusted EPS growth, excluding the impact of foreign exchange, and an encouraging start to the year, especially considering the outsized timing of defense orders that benefited the first quarter last year.” The mid-point of the adjusted EPS range of $2.82 represents 11% growth, excluding the unfavorable impact from foreign exchange of $0.12 for the full year.” By intersecting our broad portfolio of technologies with the product roadmaps of our customers, we help create differentiated and high-performance products that make the world better and more sustainable.

This hard/soft combination design has been driven by an escalating market trend pushing toward enhanced ergonomic feel and touch, gripping feel, aesthetics, cushioning against impact, vibration isolation or dampening and insulation. Rigid thermoplastics include both commodity thermoplastics and engineering thermoplastics, such as polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), polycarbonate (PC), acrynitrile-butadiene-styrene (ABS), poly(ethylene terephthalate) (PET), poly(methylmethacrylate) (PMMA), styrene acrylonitrile (SAN), poly(phenylene oxide) (PPO), polyamide (PA), PC/ABS blend and PPO/PS blend etc.. As given in Table 2, TPE-1 demonstrates good adhesion on all ten substrates with very different surface energy and polarity; from the low like PP to the high like PC and ABS.

Consumers and investors alike are paying close attention to plastic packaging and its potential negative impact on the environment. In 2019, the EU enacted its Single Use Plastics directive aimed at reducing the impact that such products have on the environment. These commitments and mandates will continue to drive the high and increasing demand for recycled plastic bottles.

This region of the world maintains a high sensitivity to preserving nature and the environment, and the producer’s desire to look for alternative material solutions not yet required by law follows this cultural tendency. THE IMPACT By replacing traditional sealing materials with non- halogenated OnFlex S HF TPE, Schneider-Electric NB (Strömfors) was able to offer its customers several significant benefits: • For flexibility in processing, OnFlex S HF TPEs can be supplied in either natural or pre-colored grades. High-flow properties of OnFlex S HF TPE allow the gaskets to be overmolded in multi-cavity tools (up to 12 cavities per tool).
