HDPE Sheet (Polystone G)

High-Densisty Polyethylene (HDPE) Sheet (Polystone® G)

Polystone® G can be efficiently machined with all known tools used in wood and metal processing.

Sawing: Fast-running circular and band saws are suitable.  Smooth surfaces can be achieved when the teeth are lightly set.  Saw blades with teeth more than 5/8" apart are sug-gested.  Especially with PP, fast chip removal is essential to prevent melting.

Milling: Fairly high feed rates and revolutions work best with atten-tion to reduce heat generation.  Suggested 9,000-12,000 rpm with a feed rate of 250-350 inches per minute.

Welding: Quality welds are achieved with the appropriate tempera-ture setting and air pressure.  The welding rod must be compatible, and along with the joint surfaces, both should be clean before starting.

Thermoforming: A controllable heating system is required that is designed to provide even heat to each point of the sheet. Typical heat time is 10 minutes per 1/8" sheet thickness.

Polystone® G (HDPE)
Extrusion welding melt temperature: 395˚F - 440˚ F
Hot gas welding temperature: 608˚F
Thermoforming temperature range: 285˚F -  300˚F

Polystone® G (HDPE) defines dependability and versatility in a wide variety of industries. A polyethylene with outstanding impact resistance and tensile strength making it the perfect choice for a wide range of applications such as:
• tanks and vessels
• food cutting boards
• light-duty tank, chute and bin linings
• playground structures
• restroom partitions
• boat accessories
