Answers to our most commonly asked questions.

Is Yulex better then Neoprene?

In its review of Patagonia’s Yulex Wetsuit, Business Insider reports that Yulex is equal to or better than Neoprene in performance, flexibility and durability and warmth. Learn more in our Rubber Chronicles.

Is Yulex better than Geoprene?

Geoprene is created from limestone, which is a non-renewable resource drilled, mined and extracted. Yulex is equal to or better than Geoprene in performance in all applications.

What are alternatives to Neoprene?

Yulex is the first sustainable, plant-based alternative to Neoprene that performs equally or better on all applications.

What is Chloroprene?

Chloroprene is another name for Neoprene, the petroleum-based wetsuit material that is fast falling out of fashion due to its harm to the planet, and its cancer-causing toxic emissions during production.

What is Acetylene?

Acetylene is made from natural gas and/or petroleum-based hydrocarbons and/or carbothermic process from limestone. It is used to make Geoprene, a non-renewable limestone-based wetsuit material.

Is Yulex solid natural rubber hypoallergenic?

Yulex natural rubber is a solid and has not been shown or known to produce any type 1 latex allergic reactions.

Is Yulex plant-based?

Yes, Yulex is produced from natural rubber trees / plantations.

What is “PEFC certified”?

Programme Endorsement Forest Certification (PEFC) provides global independent verified assurance that the certified forest-based material (e.g. natural rubber) contained in a product originates from sustainably managed forests. Learn more here.

What is “FSC certified”?

Forestry Stewardship Council (FSC), also provides global verified assurance that the certified forest-based material (e.g. natural rubber) contained in a product originates from sustainably managed forests. Learn more here.

What is YULEX PRIME?

Yulex Prime is a certified natural rubber solid grade used to make Yulex foam, yoga mats and other closed cell foams.

What is YULEX PURE?

Yulex Pure is a natural rubber latex that is up to 99% purified of non-rubber particles impurities like dirt, oils, minerals and proteins.

What is Yulex Foam?

Yulex Foam is a direct replacement for petroleum-based neoprene and geoprene. It is made from renewable natural rubber sourced from FSC & PEFC certified plantations.

Can Yulex natural rubber latex be used in place of water-based synthetic?

Yes, in most situations Yulex natural rubber latex can be used in place of synthetic water-based elastomers.

Is Yulex natural rubber solid and natural rubber latex biodegradable?

Yes, all natural rubber made from tree latex is biodegrade. Once the natural rubber is vulcanized (cured) it strengthens the natural rubber for durability, longevity and performance, and may not biodegrade in a reasonable time.

We have biodegradable screening testing pending.

Are Yulex Prime and Yulex Pure biodegradable?

See the answer above.

What is the difference between Yulex Prime and Yulex Pure natural rubber?

Both Yulex Prime and Yulex Pure are PEFC and/or FSC certified. YULEX PURE is further processed using a Yulex proprietary method to purify and remove non-rubber particles such as dirt, oil and proteins.

What is the European Deforestation-free Regulation aka “EUDR”?

The European Union to help fight climate change and biodiversity loss, now requires companies to ensure that cattle, cocoa, coffee, palm oil, rubber, soya and wood products sold in the EU and exported from the EU have not led to deforestation and forest degradation.

Frequently Asked Questions - Deforestation Regulation (europa.eu)
What do YULEX products have to do with the EU Deforestation Regulation ("EUDR")?

What is the carbon footprint if I convert from a sythetic (petroleum) to natural rubber?

Using natural rubber, especially natural rubber produced from certified smallholders, there is a reduction of over 80% CO2e emissions as compared to neoprene and even higher CO2e emission reductions for geoprene.

What is YULEX2.0?

YULEX2.0 is the name given to our new wholly-Yulex controlled supply chain and independent of other Yulex foam producers like Sheico. If you have been working with us directly, then you have been working with YULEX2.0.
