Material: HDPE,Nylon

Features:

1.High intensity, wear-resistance, corrosion-proof, with longer life span than steel buckets.
2.Light weight, extend the life span of the bucket, reduce the energy consuming of the elevators.
3.Good pliability , low product damage percent of only 1.
4.No spark caused in operation, avoid the possibility of dust exploration.
5.Clean discharge, wide temperature applications.

Technical Index:

1.Method of Manufacture : Injection molded.
2.Drilling: Free of charge. Special drilling is offered according to customers demand. (For detailed drilling specifications, pls refer to the related specification chart)
3.Bucket Spacing : Minimum bucket spacing has historically been nominal projection plus+50mm
4.Installation:Norway flat head elevator bolts, flanged bolt, sabre-tooth bolt, and belt bolt.
5.Sanitary Standard: FDAapprovalnon toxic and no causticity itselt, suitable for food industry.

Physical and Chemical Properties of HDPE

ADensity: 0.9350.960 g/cm2
BMechanical properties: Rupture strength: 900 N/cm2 Extensibility at break: 300%
