Polyethylene (PE)

Polyethylene (PE) is a thermoplastic with almost limitless applications. Read more about the different forms of PE, including marine grade high-density PE, below.

What is Polyethylene (PE)?

 

Polyethylene is a thermoplastic polymer, meaning that it responds to heat for moulding and shaping. Its versatility makes it the most widely produced plastic in the world.

Low Density Polyethylene (LDPE), the low density version of PE is is a very flexible material. Popular applications include packaging film, bin liners, single-use shopping bags, wire insulation, squeeze bottles and toys.

 

High Density Polyethylene (HDPE), the high density version of PE, is commonly used in food packaging and household items, including blow-moulded milk bottles, buckets, cleaning product bottles and lids.

Ultra High Molecular Weight Polyethylene (UHMW) is even tougher, making it the plastic of choice for high-abrasion applications, such as chain guides, marine dock fender pads and even bulletproof vests.

Marine grade HDPE supplier Gold Coast

Marine Grade HDPE (Seaboard™, Starboard®, Marine Board™)

Specialist marine formulations of HDPE, such as Seaboard™, are designed to meet the specific requirements of marine and other outdoor environments. In addition, special post-production treatment enhances the material's ability to withstand the effects of salt water, moisture and direct sunlight.

Benefits of marine grade HDPE

  • Excellent scratch resistance

  • High impact resistance and stiffness

  • UV stabilised for excellent weatherability - great wood substitute because it will not delaminate, chip, rot or swell

  • Wide range of colours, sizes and thicknesses
