HDPE & UHMWPE bars and sheets
HDPE plastic is the most environmentally stable of all plastics – giving off no harmful fumes into the environment. Manufacturing HDPE plastics requires only a fraction of the energy required to produce steel from iron ore, further contributing to its classification of being Eco-friendly & Multi Use.
