Polyethylene Sheets
Tivar polyethylene is the brand name of Quadrant Engineering Plastic Products. Tivar is an extensive range of Virgin, partially reprocessed, coloured or modified Ultra High Molecular Weight Polyethylene (UHMW) stock shapes, manufactured by compression moulding or extrusion.
In less demanding applications with respect to wear and impact resistance, PE 500 grade polyethylene may present an economical alternative for the Tivar standard grades.
There are many variations of Tivar 1000 polyethylene that have been created to meet specific market requirements. Tivar proprietary Polyethylene grades offer improved sliding and wear properties, static dissipative characteristics, enhanced release properties or improved engineering characteristics.
