Polyethylene Injection Moulding

We work with both High density polyethylene (HDPE) and Low density polyethylene (LDPE) thermoplastics.

HDPE is resistant to many different solvents and has a wide variety of applications, including:

• Water & Gas Applications
• Food
• Pipe fittings
• Wear plates
• Hinges
• Cutting boards

High density polyethylene (HDPE) is not easily glued being better suited to ultrasonic welding which is offered inhouse.

Other properties include good impact resistance, light weight, very low moisture absorption, Good chemical resistance, excellent machineability and high tensile strength

LDPE offers Excellent resistance (no attack) to dilute and concentrated Acids, Alcohols, Bases and Esters; Good resistance (minor attack) to Aldehydes, Ketones and Vegetable Oils; Limited resistance (moderate attack suitable for short term use only) to Aliphatic and Aromatic Hydrocarbons, Mineral Oils and Oxidizing Agents and Poor resistance (not recommended) to Halogenated Hydrocarbons.

LDPE is often used for molded laboratory apparatus including wash bottles, pipette washing equipment, general purpose tubing, bags and small tanks. Available in both translucent or opaque, it is quite flexible, and tough to the degree of being almost unbreakable.

Typical applications include:

• Containers
• Food
• Corrosion-resistant work surfaces
• Laboratory bottles and glassware
