LDPE, HDPE, HMWPE, UHMWPE
Polyethylene is resistant to chemicals, greases and oils, and is a dimensionally stable plastic that absorbs very little water. Colours are natural, white or black.
Low density form (LDPE) – 70°C in air: This can be used where corrosion and erosion resistance are required but if an application needs stiffness, high temperatures and structural strength then this is not the best material. LDPE is used for guide rails, impact plates and fenders.
High density form (HDPE) - 80°C in air: This grade offers excellent impact resistance, low moisture absorption and high tensile strength. HDPE is non-toxic and meets with the FDA approval for food processing. Suitable for parts including wear strips in conveyor system and ROV protection pads.
HMWPE - Ultra-high-molecular-weight polyethylene.
UHMWPE - Ultra-high-molecular-weight polyethylene, sometimes shortened to UH.
