EP-YH 31 U

EP-YH 31 U

EP-YH 31 U is a high fluidity heterophasic copolymer. The product is particularly suitable for injection moulding items that require a superior mechanical properties balance over a wide temperature range. The easy flow. of EP- YH 31 U provides outstanding processability and reduced cycle times. Items moulded with EP- YH 31 U feature excellent impact strength and good stiffness.
The mechanical properties at low temperature and dimensional stability are excellent.
EP-YH 31 U has been designed for injection moulding large items with significant impact requirements: boxes.
crates, pails and large household articles.Other applications include toys, appliance components, battery cases and some smaller items such as caps, closures and flower pots.
