1st Producer of Natural Rubber Latex in the USA

With its Guayule natural rubber farm in Arizona, Yulex became the first producer of Natural Rubber Latex in the United States. Today, Guayule natural rubber is being scaled up for global production by the world’s largest tire companies.

Patagonia steps up

After several years in development, Patagonia launched their first natural rubber wetsuit for surfers with Yulex Guayule natural rubber. To meet Patagonia’s needs and market demand, Yulex switched to producing Yulex Foam from the Hevea rubber tree, another renewable source.

The First Certified Natural Rubber Supply Chain

Yulex pioneered the introduction of FSC-certified natural rubber into the supply chain for consumer brands, and now we are introducing PEFC-certified supply chains. Still today, certified natural rubber is only about 3% worldwide. Yulex is committed to increasing this number.

The Rubber Production Experts

Yulex displays expertise in all areas of natural rubber including agriculture, materials science and processing, product prototyping, regulatory issues, sales and developing products and transparent supply chains for our customers.

Responsibility

Yulex was founded on the principle of producing responsible, sustainable, renewable plant-based products from natural rubber. Our mission is to do our part by providing a renewable, deforestation-free, traceable, replacement for toxic and harmful neoprene, and other oil-based, non-renewable, unsustainable products.

Pragmatism

We measure our impact, and respond to the data to make sure all our products perform at a high level, while minimizing environmental impact. We are forward looking and have been compliant with the EU deforestation-free products regulation.

Social Equity

We believe that all people who work in our supply chains should derive a social benefit. Through our Equitable Ag, smallholder profit-sharing program, we share profits with the our natural rubber supply chain including importantly, the smallholders.

Performance without Compromise

You should never need to choose between performance and planet. We are dedicated to providing our clients with the ability to develop high performing products with less to the environment and people.
