Cheapo plastic cooler ok for mashing?

[Deus Ex Mashina]

Brewers,
I have build a mash tun out of a 22 l picknick cooler. I bought it online, and was quite cheap, so not the best quality as the famous igloo. It works pretty ok, but I am wondering is it safe to mash in that plastic reaching temps up to 70-75C? I am afraid of the plastic when heated would give weird taste to the beer!

That’s about what i’ve been using for years. I’d bet most folks here with DIY mash tuns are using cheap old coolers.

It will make beer. Good beer.

What type of plastic is it made from (HDPE or LDPE)?
