For environmentally friendly rubber products, Natural Rubber is the obvious choice

Manufacturer: We are continuously under pressure from the market to make the so-called environmentally friendly rubber products. We have been told that natural rubber is the better choice compared to synthetic rubber. Your comment please.

Also, can natural rubber be made to have a different degree of biodegradability according to compounding formulation?

JohnWoon: Natural rubber is indeed a more biodegradable rubber compared to most synthetic rubbers. It is therefore both environmentally and ecologically more friendly. Several bacteria (micro-organism) in the soil and untreated water have been identified to be responsible for the biodegradation of natural rubber, the most common one being Nocardia asteroids. See picture below.


The environment best suits the activity of the micro-organism is normally one that ecologically has a balanced presence of oxygen, moisture, warmth, and various minerals and salts.

The thinner the rubber articles, the faster would be the degradation. Thin products such as toy balloons, condoms and medical gloves are expected to undergo biodegradation more quickly.

Yes, to a certain extent compound formulation could enhance or retard the rate of biodegradation. In my earlier posting, I recommended the EV-system to retard the biodegradation. Please click HERE.

As agreed more in-depth and detailed advice is being sent to you separately.

REACH: Redefining Supplier-Customer Relations

With the EU’s REACH legislation set to come into effect this June, suppliers and customers in the chemical industry will have to make major adjustments in their business operations to effectively navigate the new regulatory environment.

The European Union’s (EU) controversial scheme for the registration, evaluation and authorization of chemicals (REACH), will now start to come into effect in June this year with the prime aim of improving safeguards to human health and the environment.

However its implementation is likely also to have a major impact on relations between suppliers and customers..................

Approximately 30,000 chemicals or substances will have to be registered with safety data under the REACH scheme....................................... Some of the most hazardous substances will have to be replaced by safer alternatives.......
