Hello,
Please tell me how influence the mechanical properties of PBT presence of PEHD or PELD.
Thank you.

Probably ruin both materials. How do you intend to dry PBT at 120C with PE?



Politicians like to panic, they need activity. It is their substitute for achievement.
 
The two polymers are very dissimilar in polarity so compatibility is poor. You will get droplets of one polymer inside the other leading to bad mechanical properties, especially impact resistance and elongation to break.
