PVC compounds provide cost benefit and per pound of PVC in small diameter pressure water pipes and fittings, over other materials, such as copper, steel or high-performance cross-linked polyethylene (PEX). Other than being cost-intensive, copper, steel or PEX are also expensive to install than PVC pipes. In these systems, the cost of installation can be as much as ten times the cost of the pipe itself, so even small differences in the ease of installation can result in large differences in the total cost of using a substitute material instead of PVC. PVC pipe holds a commanding share in large diameter pressure water and sanitary sewer pipe because of its low cost, ease of installation, long and reliable service life, and its low replacement and maintenance cost. Ductile iron and concrete are the major substitutes in these applications, and their installation costs are higher, particularly for concrete since many more pipe joints are required. Replacement and repair costs are much higher for concrete than for PVC pipe. Additional costs are also imposed by the loss of water, due to main breaks and pumping costs, which may be higher for these surrogate materials. The higher installation cost for concrete pipe also contributes to the substitution cost for PVC in storm sewers. Therefore, PVC offers a much better cost-saving option for the aforementioned applications, both in terms of material and installation.

Automotive lightweight materials have been witnessing robust growth during the past couple of years, due to the increasing demand for luxurious, low-on-emission, safe, and high-performance vehicles. As a result, suppliers and manufacturers have introduced various solutions that not only help OEMs meet continually tightening regulations, but also satisfy the widening range of consumer personal taste. TPVs have superior strength, high-temperature mechanical properties, hot oil and solvent resistance, and better compression set than partially-cured material. These materials are blends of elastomers, typically rubbers, including EPDM, EPR, SBS, polybutadiene (BR), or butyl rubber (IIR), dispersed in a relatively small amount of thermoplastic matrix, typically polyethylene or polypropylene. Thermoplastic vulcanizates contain 60-70% EPDM and 30-40% impact polypropylene. Typical TPV applications in the automotive industry include hose coverings, gaskets, seals, convoluted boots, vibration dampeners, air inlet duct covers, bushings, strut covers, ignition components, and window seals. Cost is the biggest advantage, with TPVs being 10-30% lower than EPDM, coupled with lower weight, improved design flexibility, and recyclability. Furthermore, the light weight of TPV enables more fuel-efficient vehicles. Every 10% reduction in vehicle weight is estimated to result in a 5-7% reduction in fuel usage.

Superabsorbent polymers are used as an absorbent, as they can absorb up to 300 times of their weight in aqueous fluids. Owing to characteristics, such as protecting the skin against drying, irritation, and infections, the largest use of superabsorbent polymers is in personal hygiene products, which include feminine hygiene products, diapers, and adult incontinence products. The governments in different countries are continuously collaborating with various NGOs, media center, and various companies, to educate people about personal hygiene management. The motive behind these initiatives is to keep the environment cleaner and safer and to avoid the spread of various diseases. According to the World Health Organization, every year, around 15 million babies are born in the world and this number is increasing. With the rising infant born rate and increasing awareness toward hygiene of a baby, the demand for superabsorbent polymers is increasing.

Historically, there have been instances of men and women using hair wigs and extensions for several purposes including trying out different hairstyles, using colored hair to change their appearance, and covering bald patches of the head. Currently, hair loss is a serious health issue. Hectic lifestyles and improper consumption of essential nutrients have adverse effects on the human body. From invisible effects such as general weakness, reduced stamina, sleep problems, and hectic lifestyles can cause several hair problems. Alopecia, receding hairline, and pattern baldness are more common in men while hair thinning is more common among women.
