ExxonMobil Chemical has introduced a new low viscosity Vistamaxx ™ high performance polymer for hygiene and assembly hot melt adhesive applications.

Vistamaxx ™ high-performance polymers enable companies to develop innovative solutions that improve product performance and productivity. It also has the potential for sustainable development by thinning the packaging film, reducing the amount of material used, reducing the thickness of hard packaging, and increasing product strength to avoid damage or waste. At the same time, it also achieves lower processing temperatures, thus reducing energy consumption.

Vistamaxx ™ polymers provide soft imitation in non-woven applications and provide a true soft touch experience in polypropylene applications. ExxonMobil ™ SFT315 Polypropylene resin provides cotton-like softness, excellent drapability, and good adhesion for spin-on processing. Excellent performance in increasing the flexibility of non-woven fabrics.

Vistamaxx Polymers provide excellent adhesion properties, bond strength and composite integrity for efficient barrier properties in food packaging films. Use Vistamaxx polymers to help keep food fresh and colored. They also provide excellent adhesion properties for strong extrusion coating and compounding applications such as polypropylene woven bags. The low viscosity Vistamaxx polymers make hot melt formulations ideal for high performance, low odor, lighter colors and low density in packaging, hygiene and assembly applications.

Vistamaxx polymers provide excellent adhesion to high performance surface protection films found in consumer electronics, LCDs and displays. Vistamaxx polymers also provide excellent adhesion in hand-drawn, machine-drawn, and stretch-wound films packaged in machine pre-stretched pallets.

Achieve excellent barrier properties with the peroxide-free metallocene Achieve ™ 6936G2 resin. Its low extractability, ultra-high melt flow rate, narrow molecular weight distribution and other characteristics make fabric processing cleaner and more efficient.

ExxonMobil ™ PP3155 polypropylene resin is especially suitable for high quality fabrics that require good spinnability and are stable at high speeds.

Metallocene Achieve ™ 3854 resin is designed for high tenacity spunbond and low-denier fibers. It enables fine fibers to maintain excellent uniformity in high-speed textile processes. Its stabilizer combination is suitable for the vast majority of non-woven fabrics and monofilaments.

For nonwovens, many factors influence the choice of fibers, the fabric forming and the web fixing process, including process efficiency, product performance, application requirements, consumer needs, and cost of use. Omnova's polymers offer greater flexibility in the decision-making process of combining and finishing / surface treating these important processes. For the currently used volatile feedstocks, nonwovens manufacturers are looking for flexible combinations using different fibers and polymers. In spunlaced wipes, the raw material mixture usually consists of 50% absorbent fibers (viscose) and 50% non-absorbent fibers (polyester or polypropylene), depending on the price of the raw material. For the moment, In many wipe products, the percentage of viscose is reduced, which can have a negative impact on absorbency and softness.

However, by using Omnova's new, innovative SoftWick SF20 finishing process, wipe manufacturers will be able to reduce the amount of viscose fiber with little if any impact on performance. SoftWick SF20 will help provide better wicking and utilization of the best surface to increase the overall absorbency of the wipe. In addition, SoftWick SF20 will help to achieve a more soft feel. In addition, Omnova's Sunbond adhesives help improve the wet tensile strength of household and industrial wipes in spunlace.

In addition, softer products and sustainable solutions (from an environmental point of view) are a clear trend towards the ultimate use of absorbent hygienic products. Due to global demand, viscose prices, very little increase in production capacity, cotton can play an important role in non-woven applications. Cotton is stronger than pulp and viscose, has high hydrophilicity, softness, and is a symbol of environmental protection. Therefore, cotton has a very wide acceptance as a raw material, especially in Asian countries. However, the higher the cotton content, the weaker the fabric due to the lower number of bonds. Therefore, hot rolling, needling and spunlacing do not provide an effective netting process for the desired strength of the material. However, polymer bonding may be the most effective fiber-binding technique, and cotton can be used more widely as a raw material.

Acrygen 27 is a self-crosslinking acrylic adhesive that provides firm operability and moldability to nonwovens and textiles.

GenFlo 3003 is a carboxylated styrene-butadiene copolymer binder for high-performance nonwovens applications in applications such as the deflector and floor mats for disposable hygiene products.

Omnova Solutions, which has been serving the textile and nonwovens industry for more than 60 years, combines adhesives from some of the world's most recognized brands in the durable and non-durable nonwovens and apparel industries while providing a wide range of commercial, Emulsion polymers, specialty chemicals, decorative products and functional surfacing materials for industrial and residential terminal applications. These chemicals further enhance product performance with powerful water repellent technology, as well as products that give soft and durable stamping properties to apparel and other fabrics. The product portfolio is also used for wipes, diapers, filters and various other technical textiles. In addition, OMNOVA's antioxidants and elastomer modifiers are used in the rubber components of elastic belts and other stretchable materials to give product elasticity and anti-aging properties.
