Peroxides – some chemicals are activated with high temperatures, creating free radicals. The radical removes a hydrogen atom from the carbon atom in the chain of polyethylene, leaving the D-radical. This active molecule can connect with and form a similar relationship, ie crosslinks.
The most popular peroxide – 2,5-dimethyl-2 ,5-di-(butylperoxy) hexane. At room temperature – in [...]

This technique of accelerated laboratory tests designed to characterize the effect of mold on the properties of PEX materials. This method also allows to evaluate the effectiveness of antimicrobial additives introduced into the plastic.
Test procedure is that the suspension is prepared spores from cultures that are most active when exposed to polymers. This method, if [...]
