In an earlier blog we talked about DaRo’s plastic manufacturing and plastic vacuum forming sections but it is interesting for our customers to know a bit more about the extensive range of high quality plastics we use and their individual properties.

Below is a brief description of some of our most frequently used materials although this listing is by no means exhaustive.

Acrylonitrile Butadiene Styrene (ABS)

Properties:

One of the most widely used plastics in vacuum forming, it is an easily formed and machined, tough, low cost rigid thermoplastic with high impact strength, recyclable, ideal for moulding, turning, drilling, milling, sawing, die-cutting, shearing. Readily available in a wide range of colours and surface finishes.

Used where:

When aesthetics and dimensional accuracy are essential and for applications where a product needs to be tough and shock absorption is critical such as in automotive parts and enclosures.

 

High Impact Polystyrene (HIPS)

Properties:

HIPS is a cost-effective material that is relatively easy to form, machine and fabricate, paint and glue. It has excellent dimensional stability and is readily available in a wide range of colours, gloss and Matt finish but without the impact strength of ABS.

Used where:

As HIPS is FDA compliant it is used widely in the food, dairy, and medical packaging industries. Also commonly used for point of sale displays.

 

High-density polyethylene (HDPE)

Properties:

Easy to vacuum form and stronger than standard polyethylene, HDPE plastic is resistant to acids, alcohol, oils and grease. A tough, durable material that can withstand an extreme temperature range.

Used where:

Highly suitable for manufacturing processes such as vacuum forming, injection moulding and blow moulding, HDPE is found in many applications such as food packaging, cleaning product containers, meter and valve boxes and garden furniture. Due to its strength and chemical resistant properties it is an Ideal material for vacuum formed transit trays for the manufacturing industry.

 

Polycarbonate (PC)

Properties:

Polycarbonates are strong, stiff, tough, hard, transparent engineering thermoplastics that can maintain rigidity up to 140°C and toughness down to    -20°C. The material displays excellent mechanical properties and high dimensional stability, is thermally resistant up to 135°C and rated as slow burning. Special flame retardant grades exist which pass several severe flammability tests.

Used where:

Due to its transparency and excellent toughness, Polycarbonate (PC) is one of the most widely used engineering thermoplastics ideal for vandal proof glazing, riot shields, baby feeding bottles, safety helmets and light lenses.

 

Polyethylene Terephtalate Glycol-modified (PETG)

Properties:

Lightweight and transparent, PETG is a thermoplastic sheet material with outstanding thermo-formability and good impact resistance. It also makes a good gas, alcohol and solvents barrier.

Used where:

Typical applications include, packaging such as blister and clam packs, Point-of-Sale displays, merchandising displays, transit trays, prototype models, machine guards and housings.

 

Polyvinylidene difluoride (PVDF)

Properties:

PVDF is used most often in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat. It can also withstand exposure to harsh thermal and chemical conditions and is unaffected by long-term exposure to ultraviolet radiation.

Used where:

Applications include chemical tank liners, semiconductor equipment components, pump and valve parts and flanging.
