FAQ

Frequently asked questions

Can I use Bio-MPG directly instead of conventional MPG?

Yes. Bio-MPG is chemically identical to petrochemical propylene glycol. Existing antifreeze and heat transfer formulations can remain unchanged.

Which documents do I receive?

Technical data sheet, safety data sheet (DE/EN) and certificate of analysis per batch. Sustainability and CO₂ evidence is provided per product where available from the manufacturer.

Which quantities and packaging are available?

From drums and IBCs to ISO tank containers. Pack sizes depend on density and product – details are given on each product page.

Can I request a sample?

Yes. Send us the product, application and planned annual volume – we will get back to you with a sample, data sheets and a quote.

Which glycol fits your circuit?

Tell us the application, temperature range and annual volume – we reply with a recommendation, sample and quote.
