Platinum Cured Silicone Washers

ASG are leading converters and suppliers of components many of which are made using a diverse range of sponge and silicone rubber materials, these include Platinum Cured Silicone Washers.   

Platinum Cured Silicone Rubber is manufactured as continuous rolls of material usually in widths of 1.2 or 1.4meters and roll lengths of 5meters or 10meters depending on the material thickness which range from 0.5mm to 2mm, but as this solid rubber can be extruded, bespoke thicknesses to order, all of which can be cut down into washers. Using high quality material and state of the art machinery, our in-house conversion facilities produce a range of Platinum Cured Silicone Washers,  all made to order and produced by using samples or drawings as a template to ensure the final product perfectly fits the application - even offering a small sample batch if required for testing. 

Depending on the size and quantity of washers required, our production team will select from our range of atoms, autos, travelling head, kiss cut presses or for very large or thick washers, we can programme our CNC (oscillating knife) to produce the washers in the most efficient way to keep quality high, whilst keeping costs competitive and lead times as low as possible.

    What are Platinum Cured Silicone Rubber Washers?

    Platinum Cured Silicone Washers are a flat ring  comprising of an outer diameter (OD), inner diameter  (ID) and the thickness,  cut from a sheet or roll of material, which is placed between two surfaces creating a level surface, acting as a spacer or between a nut and bolt to spread the pressure when tightened or to create a better fit for fittings such as screws and bolts.

    Manufacturing washers in-house means we can offer the option to supply them in a plain or self adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.   Unlike many traditional Peroxide cured materials and rubber products, during the formulation of Platinum Cured Silicone, peroxides aren't used as part of the catalysing process.  

    When using peroxides, traces can often remain in the raw material causing contamination and so silicone manufactured using Platinum Curing and the washers cut from them are a more popular choice in industries including medical, food, drink or dairy applications as it is considered a cleaner/purer product.  Platinum Cured Silicone Washers are also translucent in colour and appearance - again perfect for the food and drink industries where visibility is crucial, it is also non-toxic and non yellowing.

    Why use Platinum Cured Silicone Washers?

    Platinum Cured Silicone Washers are a safe and versatile, popular for use in the food, drinks and pharmaceutical industries.  The rolls of material itself are easy to convert into a range of products including washers for use in various applications.  

    Platinum Cured Silicone Washers can be used with applications where there is exposure to extreme temperatures offering an operating temperature range of -40°C to +200°C, radiation, corona, moisture and steam. 

    Platinum Cured Silicone Rubber is peroxide free, non toxic and non yellowing.  It’s an extremely flexible and durable material offering good weathering, UV and Ozone resistance.  Platinum Cured Silicone Washers are used as a type of seal, where they can create air or liquid tight seals, as gap fillers for uneven surfaces.  They can also be used to reduce friction between moving parts.

    Different Grades

    Advanced Seals & Gaskets Ltd have a network of material manufacturers and suppliers, giving our customers more choice, our most popular grades of silicone rubber include:

    • High Temperature Silicone - FDA approved and suitable for working conditions up to 300°C
    • FDA Approved Silicone - all general purpose silicone are certified for use within food, drink &  pharmaceutical applications
    • Metal Detectable Silicone - used to detect metal fragments 
    • Fluorosilicone - this material offers the same mechanical properties as standard silicone, but with an improved fuel and mineral oil resistance. 
    • Conductive Silicone is a carbon filled silicone which conducts a low electrical amperage

    Flame retardant offers a more superior flame retardance, meeting  the following standard for railways BS6853 Cat1A and French Norm NFF 16-101 (now superseded by TS EN 45545-2)

    Benefits of Platinum Cured Silicone Rubber

    • Peroxide Free
    • Non-Toxic
    • Non-Yellowing & excellent translucency so more visibility
    • Durability with a high tear strength 
    • Lightweight
    • Easy to cut 
    • Highly hydrophobic

    Advantages of Using Platinum Cured Silicone Rubber Washers

    Platinum Cured Silicone Washers are used for a number of reasons and are especially popular within the food, beverage and medical industries due it being peroxide free, non-toxic and offering excellent purity. 

    Platinum Cured Silicone Washers are translucent in colour and non-yellowing which makes it perfect for use in sensitive environments as it will not contaminate any food, medicines or liquid it comes into contact with.   Platinum-cured silicones other properties include chemical inertness, higher levels of tensile strength, elongation, and tear strength.  

    These washers have an operating temperature range of -40°C to +200°C,  and can be used in applications where a resistance to radiation, corona, ozone exposure, moisture, and/or steam is desired. 

    The curing process for producing Platinum Cured Silicone materials is not only peroxide free, but also emits the use of talc - a mineral which has been known to cause health issues.  Platinum Cured Silicone can be taken in full rolls or sheets of material or alternatively converted here at ASG into a range of other products including  washers, gaskets, strips pads and other seals.
