Polyethylene: HDPE, HMWPE & UHMWPE
Bay Plastics offers a superb selection of polyethylene sheet and rod in three different grades with custom sizes available.
High density polyethylene is commonly abbreviated as HDPE and also referred to as PE300. HDPE is used in a variety of applications and industries where excellent impact resistance, high tensile strength, low moisture absorption and chemical and corrosion resistance properties are required. HDPE in the natural colour finish also meets the FDA/USDA food handling guidelines.
High Molecular Weight Polyethylene is commonly abbreviated as HMWPE and also referred to as PE500. HMWPE is commonly used as wear parts and abrasion resistant components in the conveyor and materials handling industry. HMWPE is used in food preparation and chopping boards because its slightly softer than UHMWPE - PE1000 grade and better for the cutting equipments. Also, HMWPE offers a better consistent and durable cutting surface than HDPE.
Ultra High Molecular Weight Polyethylene is commonly abbreviated as UHMWPE and also referred to as PE1000. Polyethylene PE1000 grade offers exceptional and unique combination of low friction surface, great impact strength and wear and corrosion resistance. UHMWPE retains key physical properties and high impact strength, even at low temperatures down to -30°C. This excellent general-purpose plastic with self lubricating properties offers noise reduction and low friction surface. UHMWPE offers good chemical resistance and low moisture absorption. UHWMPE (natural) is an outstanding solution for food handling components, and meets FDA, USDA and 3-A Dairy guidelines for food processing and handling.
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 (UHMWPE) 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.
