Plastazote Foam Pads

Advanced Seals & Gaskets Ltd pride itself on being able to work with a multitude of reputable material manufacturers and suppliers, enabling us to offer pads cut using a range of materials in many grades, densities and colours. Our more popular materials include various types of Polyethylene (PE) foam, one of which is Low-Density Plastazote foam in densities ranging from 15kg to 70kg (referred to as LD15, LD33, LD45, LD60 or LD70 respectively). 

This material is a closed-cell, cross-linked polyethylene foam which is incredibly lightweight, and free from chemical agents which enable customers to use this material in highly sensitive environments.  Plastazote PE foam is manufactured and stocked in block form from which we can convert sheets and rolls of various thicknesses from which pads can be cut.  

Our pads are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification.  Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one-off samples to multiple batches runs, which can be supplied as loosely cut parts, or kiss-cut on rolls where a high quantity is required or for use on fast-paced assembly lines.

What are Plastazote Foam Pads?

Plastazote foam is a cross-linked, closed-cell polyethylene foam, man-made using crude oil into which nitrogen is blown and the foam is expanded. This manufacturing process produces a tough and flexible material. 

When the plastazote foam has compressed each nitrogen-filled cell acts like a balloon, causing the foam to bounce back to its original shape. Being a closed-cell structure of plastazote means it is impenetrable to air and moisture and will not allow liquids to pass through or be absorbed making it an excellent choice for cutting into pads.  

Plastazote foam pads are cut from rolls or sheets of material and are often used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities.  Our pads can be produced as squares or rectangles with the option of radius corners, and also as circular or oval-shaped pads or ‘discs’,  in a range of thicknesses. 

Manufacturing pads in-house even means we can supply them in a plain or self-adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.

    Why use Plastazote Foam Pads?

    Plastazote is a very low-density foam that can be easily split, cut and shaped.  Even with such low density, it still offers excellent compression following compression and impact.  It offers resistance to a range of chemicals, solvents, acids, alkalies and some oils, meaning it can be utilised in many applications. 

    All Plastazote materials are lightweight and free from chemical agents, therefore can be used in many ‘clean’ applications such as food, pharmaceutical and science. Plastazote foam pads are used to fill gaps and irregularities between uneven surfaces and to provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving parts to reduce friction and damage to components and equipment.

    Advantages of using Plastazote Foam Pads

    Using Plastazote foam offers countless advantages and is highly utilised in numerous industries and applications,  Plastazote foam is a man-made material, designed to suit a range of requirements and is available in a choice of grades, densities and colours to suit.  Plastazote foams are odourless, lightweight, buoyant, non-toxic and offer resistance to many oils, solvents, acids and alkalis.  

    Its closed-cell surface does not allow the absorption of liquids and is easy to keep clean, as well as being weatherproof and UV stable.  Plastazote foams are usually the preferred choice for protective packaging such as case inserts, but also popular for the production of pads as the material has excellent recovery from repetitive impact, vibration reduction and abrasion resistance.  

    Using these materials for pads offers customers cost-saving benefits as there is a reduction in damage to products and equipment from unwanted movement, vibration or the intrusion of water and dust.

    Typical Applications for Plastazote Polyethylene foam

    Plastazote polyethylene foam is most commonly found used in packaging applications, being low density, plastazote can be easily cut and manipulated to fit around delicate or fragile products. Other applications can include:

    • Making costumes or props
    • Displays
    • Used in the manufacture of sports equipment 
    • Water repellent and buoyant for use as floatation or buoyancy aids
    • Used for surface protection and components for medical and healthcare applications
    • Footwear lining
    • Electronics packaging

    Benefits of using Plastazote foam
