ExxonMobil Chemical Polymers Help Protect Crops in a Variety of Agricultural Applications

Sustainability Challenge:

A growing global population needs access to a plentiful, healthy food supply.

Chemistry Solution:

Durable agriculture films made from polyethylene polymers help extend growing seasons, promote crop growth and reduce food waste and spoilage.

Sustainability Benefit:

Farmers can produce a range of crops to address global food needs.

With the global population expected to expand by 2 billion people over the next 25 years, enhanced agricultural efficiencies are vital to help feed people all around the world.

To help meet this challenge, Exceed™ XP performance polymers, developed by ExxonMobil Chemical, can help protect a broad range of crops in a variety of demanding agricultural applications:

  • Agriculture films made using Exceed XP can preserve agricultural harvests through changing weather conditions and seasons, helping farmers protect and grow their crops. By maintaining integrity in demanding conditions, these films help prevent damage to crops in the field and during handling, reducing the risk of waste and spoilage.

  • Greenhouse cover films made from Exceed XP improve moisture retention, provide temperature management and protect crops from the environmental elements, to help extend growing seasons for fruits, vegetables and flowers. These greenhouse films can help farmers economically increase their efficiency to feed more people, while also helping to conserve resources such as water, nutrients and fertilizers.

  • On farms, long-lasting mulch films can help increase crop production rates and allow farmers to spend time on more productive activities rather than collecting mulch film that has broken down.

  • In addition, durable, crack-resistant films made with Exceed XP help create flexible food packaging like stand-up pouches (SUP) and bags that can withstand demanding environments, such as freezers, or be capable of holding larger and heavier contents. This includes packaging for frozen food, dry food, and meat and cheese products, so brand owners can protect and preserve their food products from production to the table.

Polyethylene Orthopedic Implants Developed by Celanese Can Help People Stay Active & Healthy

Sustainability Challenge:

With an aging global population, the need for high-quality orthopedic implant materials is growing.

Chemistry Solution:

Orthopedic implants developed by Celanese made from ultra-high molecular weight polyethylene can provide high-quality knee and hip replacements.

Sustainability Benefit:

People can continue to stay active longer, enhancing their health and wellness.

Today, people are living and remaining active longer than ever, and they often want to keep enjoying active hobbies and exercise into their 70s and 80s, and beyond.

According to the American Academy of Orthopedic Surgeons, more than 7 million Americans are living with an artificial knee or hip today, and that number is expected to increase. Joint replacement surgery is done primarily to relieve the symptoms of osteoarthritis and to treat fractures, with the goal of enabling patients to resume their normal activities with less pain and stiffness and enjoy a higher quality of life.

ultra-high molecular weight polyethylene (UHMWPE)Each year, about 3 million joint replacement procedures are performed globally, the majority of which incorporate ultra-high molecular weight polyethylene (UHMWPE) as the articulating bearing surface to cushion prosthetic parts in hips, knees and other joints.

GUR® ultra-high molecular weight polyethylene, developed by Celanese, is a premium grade material that is often a choice in orthopedic implants for artificial hips, knees and other large joints for more than 40 years.

UHMWPE is a bio-compatible, chemically inert, strong, tough polymer with good load bearing resistance. It is self-lubricating, mimicking the natural lubricity between the cartilage and the joint. With a significantly higher molecular weight than standard polyethylene, UHMWPE exhibits high performing impact strength for energy absorption and excellent abrasion/wear resistance, enabling artificial knees and hips to last longer, so seniors can continue participating in the activities that they enjoy.

Today, most implants are treated by modern irradiation techniques for sterilization and performance improvement. To further enhance safety of implants, Celanese technology innovations include Vitamin E (anti-oxidant) filled grades that help prevent oxidation and degradation in the mechanical properties of the implants.

The extensive clinical history of UHMWPE materials continues to expand beyond its original end use in orthopedics into new potential applications.
